Aluminum Dross Separating Drossing Flux is a highly efficient slag remover specifically designed for the die-casting and recycled aluminum processing industries. This flux is primarily utilized to facilitate the separation of oxide slag—accumulated on the surface of molten aluminum—from the liquid metal itself. The recommended addition rate is 0.2% to 0.4% of the total melt weight; however, users may flexibly adjust the dosage based on actual operating conditions. When used under high-temperature conditions exceeding 700°C, the product fully maximizes its slag-aluminum separation efficacy, thereby significantly reducing the loss of valuable aluminum metal typically entrained during the manual skimming process. In terms of packaging, the product is available in three distinct bag sizes—1 kg, 2.5 kg, and 5 kg—to facilitate convenient and precise dosing across various production batch sizes. Overall, with its precise dosage range, proven high-temperature adaptability, and targeted application scenarios, this product serves as a practical auxiliary material for aluminum processing enterprises seeking to enhance aluminum recovery rates and improve melt quality.

**Key Advantages**
Aluminum Dross Separating Drossing Flux demonstrates several core advantages during aluminum slag separation operations. First, the addition rate is flexible and controllable; the base recommended ratio of 0.2%–0.4% covers the vast majority of operating conditions encountered in die-casting and recycled aluminum smelting. Furthermore, the product supports on-site fine-tuning "as needed," allowing operators to freely optimize the dosage based on factors such as slag volume and aluminum melt quality—thereby preventing waste while ensuring effective separation. Second, the product exhibits outstanding high-temperature adaptability; it is specifically designed for use when the melt temperature exceeds 700°C. Within this temperature range, the flux reacts rapidly with the oxide slag, causing the slag layer to become dry, loose, and naturally buoyant. Unlike products that may suffer from clumping or incomplete separation at lower temperatures, this flux ensures the smooth and efficient execution of the slag-skimming process. Third, the packaging system offers exceptional practicality: the 1 kg small bags are ideal for precise manual dosing or trial testing; the 2.5 kg bags meet the requirements of standard furnace batches; and the 5 kg large bags are compatible with automated dosing systems or large-scale furnace operations. These three distinct sizes seamlessly cover the entire spectrum of applications, ranging from laboratory-scale experiments to full-scale industrial production. It minimizes dust generation and material loss associated with on-site repackaging. Finally, the product focuses on two core sectors—die casting and recycled aluminum production—addressing common critical pain points inherent to these processes, such as severe oxidation of molten aluminum and high aluminum content within the dross. By effectively reducing the proportion of residual metallic aluminum trapped in the dross and enhancing melt purity, the product minimizes slag inclusion defects in castings and boosts metal recovery efficiency for recycled aluminum enterprises.

**Product Application**

Aluminum Dross Separating Drossing Flux is specifically designed for slag-aluminum separation operations during the smelting of aluminum and aluminum alloys, making it particularly suitable for die-casting workshops and recycled aluminum processing facilities. In practical application, once the temperature of the molten aluminum has stabilized above 700°C, operators should uniformly sprinkle the slag remover over the floating dross layer on the melt surface at a ratio of 0.2% to 0.4% (or at the optimal dosage determined via on-site small-scale trials). Leveraging the product's high-temperature reactive properties, the typically viscous oxide dross—which often encapsulates significant amounts of molten aluminum—gradually transforms into loose, dry solid granules that naturally detach from the pure molten aluminum beneath. At this stage, operators need only use a skimming tool to gently scrape away the dross; the clean molten aluminum flows back into the furnace bath, thereby significantly reducing the metal loss typically associated with dross removal. For the die-casting industry, using this product effectively enhances the quality of the molten aluminum, thereby reducing defects in die castings—such as porosity and shrinkage looseness—that are often caused by slag inclusions. For recycled aluminum enterprises—which frequently process scrap aluminum feedstock characterized by complex compositions and high degrees of oxidation—this slag remover consistently facilitates efficient slag-aluminum separation, helping companies boost their aluminum recovery rates and lower production costs. Regarding packaging, 1 kg, 2.5 kg, and 5 kg bags are available to accommodate varying furnace batch sizes: 1 kg bags are recommended for small-scale trial furnaces or manual addition; 2.5 kg bags are suitable for medium-sized smelting furnaces; and 5 kg bags are the preferred choice for large-scale centralized smelting operations or automated feeding systems, ensuring operational convenience and minimizing waste. Through the judicious use of this product, aluminum processing enterprises can achieve cleaner, more cost-effective production operations while simultaneously maintaining high smelting efficiency.

Sodium-free refining agent is a treatment aid specifically designed for the purification of aluminum and aluminum alloy melts. Its core feature is that it is completely free of sodium. The recommended addition amount is 0.1%-0.4% of the weight of the aluminum alloy charge, but companies can adjust this flexibly based on the actual melt conditions and process requirements. The operating temperature must reach 700-740℃ and above; within this range, the refining effect is stable. The product is supplied in bags, available in 1 kg/bag, 2.5 kg/bag, and 5 kg/bag sizes, facilitating charging operations and inventory management for smelting furnaces of different sizes. Its sodium-free formula makes it particularly suitable for high-end aluminum alloys sensitive to sodium content, balancing refining efficiency and material safety.

Main Advantages

Sodium-free formula, avoiding sodium embrittlement risk: The product contains no sodium, fundamentally eliminating the increased embrittlement caused by sodium segregation at aluminum alloy grain boundaries. It is particularly suitable for aluminum alloys requiring high plasticity and toughness (such as aluminum-magnesium-silicon alloys and aluminum-magnesium alloys) and workpieces requiring subsequent anodizing treatment.

Wide addition range and high operational flexibility: An addition ratio of 0.1%-0.4% can be used as the standard refining dosage, or adjusted temporarily according to the actual impurity content in the molten aluminum. Technicians can handle batch-to-batch melt quality variations without frequently changing the refining agent type.

Suitable for mainstream melting temperatures: Temperatures of 700-740℃ and above cover the actual operating window for most aluminum alloy melting, holding, and refining processes. There is no need to deliberately change the existing furnace temperature regime to use this product; it can be directly integrated into the existing production rhythm.

Diverse packaging specifications and convenient feeding: Three small bag packaging options are available for single or multiple feeding needs in small-batch trials (1kg), medium-sized furnaces (2.5kg), and large furnaces (5kg). The bags can be directly added to the furnace or blown out after opening, reducing scattering losses and weighing errors.

Highly versatile and compatible with various processes: It can be used with a powder sprayer to inject powder into molten aluminum as a carrier gas, or manually added with stirring when no powder spraying equipment is available, adapting to aluminum alloy production workshops with varying equipment levels.

Product Applications

Sodium-free refining agent is primarily used in the refining and purification process of molten aluminum alloys. In practical applications, when the temperature of the molten aluminum rises to above 700-740℃, operators add a sodium-free refining agent to the furnace at a ratio of 0.1%-0.4% (this can be achieved by dispersing the agent with a powder sprayer or manually sprinkling it onto the surface of the melt and pressing it below the liquid surface). At high temperatures, the product rapidly reacts with or physically adsorbs hydrogen and non-metallic inclusions (such as alumina film, carbides, etc.) in the molten aluminum, causing these impurities to aggregate and float to the surface of the melt, forming easily removable dry scum. Because the formula does not contain sodium, the refining process does not introduce additional sodium ions into the molten aluminum, thus avoiding the negative impact of sodium on the mechanical properties (such as elongation and impact resistance) and corrosion resistance of aluminum alloys. This product is widely applicable to the pre-smelting and refining processes of aluminum processing products with strict sodium content restrictions, such as cast aluminum alloys (e.g., wheel hubs, engine parts), wrought aluminum alloys (e.g., extruded profiles, plates, bars), and high-purity aluminum foil and can stock. Simultaneously, for smelting enterprises using recycled aluminum as raw material, the sodium-free refining agent can remove impurities while preventing sodium accumulation, thus improving the quality stability of recycled aluminum products. Each bag of product is packaged by weight, facilitating direct calculation of usage by furnace batch by shift personnel, reducing on-site weighing steps, and improving production efficiency.

Product Applications

**Calcium Impurity Removal in Recycled Aluminum Alloy Smelting**
When producing aluminum alloys using recycled raw materials such as scrap aluminum and old aluminum, impurities with high calcium content (such as certain coatings and inclusions) are often present in the raw materials, leading to excessive calcium content in the melt. Aluminum Alloy Calcium Remover No. 1 can be added before or after the regular refining process or during a dedicated calcium removal step to effectively reduce the calcium content to within the allowable range for the target grade, improving the purity and market value of recycled aluminum products.

**Composition Fine-tuning for Specific Aluminum Alloy Grades**
Some high-requirement aluminum alloy grades (such as certain 5-series and 6-series alloys) have strict upper limits on calcium content. If excessive calcium is accidentally introduced during smelting or batching, this product can be used as a remedial measure, selectively removing calcium without affecting the content of other beneficial elements (magnesium, silicon, copper, etc.), helping the melt quickly return to the standard composition range.

**Prevention of Casting Defects and Improvement of Machining Performance**
For processes such as die casting, sand casting, and low-pressure casting, excessive calcium content reduces the flow properties of aluminum alloys, leading to poor filling and increasing the risk of hot cracking and mold sticking in castings. Adding this product at 710-740℃ significantly improves melt purity, enhances filling capacity, and reduces shrinkage porosity, gas pockets, and microcracks, resulting in castings with higher density and better machinability.

Flexible Use in Melting Processes: This product can be added after the aluminum alloy has completely melted but before refining, utilizing the reaction time to allow for thorough calcium separation; it can also be used in conjunction with refining agents and covering agents to achieve synergistic treatment of calcium removal, degassing, and slag removal. The 5 kg/bag packaging facilitates multiple or batch additions, allowing for flexible adjustment of the total dosage based on furnace capacity (from hundreds of kg to tens of tons).

Removal of Calcium Residue During Regular Furnace Maintenance: In smelting furnaces and holding furnaces operating continuously for extended periods, calcium deposits may gradually accumulate on the furnace walls or bottom, causing repeated contamination of new melt. Regular "furnace cleaning" with this product effectively dissolves and removes these stubborn calcium residues, extending furnace lining life and ensuring batch-to-batch compositional stability.

Utilizing a scientifically formulated active system, this product rapidly identifies and reacts with free calcium within the melt—specifically within the temperature range of 710–740°C. This reaction generates compounds that are insoluble in liquid aluminum; these compounds subsequently float to the surface to form a slag layer, thereby achieving an effective reduction in calcium content. The product offers flexible and controllable application: users first determine the excess calcium level within the furnace, then calculate the required dosage based on a ratio of 7–8 kilograms of Decalcifier No. 2 needed to remove every 1 kilogram of calcium—adhering to the principle of "adding exactly what is needed to compensate for the deficit." The product is supplied in sealed 5-kilogram bags, allowing for convenient, on-demand dispensing and batch-wise addition; this makes it suitable for use in both small-scale experimental furnaces and large-scale industrial production furnaces. Through the application of this product, the purity and mechanical stability of aluminum alloys are significantly enhanced, laying a solid foundation for subsequent casting and processing operations.

Key Advantages
Clear Ratios, Precise Dosage Control
Calcium Remover Flux 2# Multi Effect Cleaning Purifying Flux establishes a clear practical reaction stoichiometry: "7–8 kilograms of decalcifier corresponds to the removal of 1 kilogram of calcium." Process engineers need only calculate the mass of excess calcium—based on analytical results such as spectroscopic analysis—to quickly determine the exact weight of decalcifier required. This approach eliminates the waste and incomplete removal issues often associated with empirical, rule-of-thumb dosing methods. This data-driven dosing model is particularly well-suited for aluminum alloy production environments where strict compositional control is a critical requirement.

Excellent Temperature Adaptability; Does Not Disrupt Normal Smelting Rhythm
The recommended operating temperature range of 710–740°C aligns perfectly with the typical smelting temperatures for common aluminum alloys (such as A356, ADC12, and 6063... ...etc.)—specifically within the standard temperature ranges for melting, holding, and refining. Its application requires no separate heating or cooling cycles, nor does it necessitate extending the holding time; the decalcification process can be seamlessly integrated with slag skimming, modification, or grain refinement treatments, thereby having a negligible impact on the existing production rhythm.

**Gentle Reaction: Protecting Furnace Linings and Tools**
Upon contact with molten aluminum, this product does not generate violent exothermic reactions or excessive fumes. The reaction is stable and controllable, minimizing splashing risks and ensuring a high level of operational safety. Furthermore, its chemical properties exhibit low corrosivity toward graphite rotors, ladles, and furnace lining materials, thereby helping to extend the service life of in-furnace tools and reduce the frequency of equipment maintenance.

**Yielding Higher-Quality Molten Aluminum; Reducing Scrap Losses**
Excessive calcium content directly leads to reduced fluidity in aluminum alloys, an increased propensity for hot tearing, and a deterioration in surface quality. By utilizing "Decalcifier No. 2" to maintain calcium levels within acceptable limits, the castings' gas tightness, elongation, and impact resistance can be restored to optimal levels. This effectively minimizes the generation of defective products caused by calcium-related flaws, thereby boosting the overall material yield rate.

**Practical Packaging: Adapted for Multi-Batch Production**
The standardized small-package design—5 kg per bag—facilitates easy handling, weighing, and incremental addition. Whether the treatment volume for a single furnace is 500 kg or 5 tons, operators can flexibly select the required number of bags, thereby preventing any remaining product from being exposed to moisture for prolonged periods after a bag has been opened. The bag material itself possesses inherent moisture-proof and tear-resistant properties, making it ideal for both warehouse storage and on-site usage.

**Product Applications**

**Targeted Removal of Calcium Impurities in Recycled Aluminum Melts**
Recycled aluminum scrap often carries residual calcium (e.g., from calcium-containing coatings or metal attachments), resulting in elevated calcium levels within the recycled aluminum melt that fail to meet the stringent requirements of high-end alloy grades. By adding this product to the melt at temperatures between 710°C and 740°C, calcium impurities are selectively concentrated into the slag phase and subsequently removed during slag skimming. This process brings the chemical composition of the recycled aluminum melt closer to that of primary aluminum, thereby enhancing the product's market value and competitiveness.

**On-Line Composition Correction for Aluminum Alloy Foundries**
During the production of high-performance aluminum alloy components for the automotive sector (such as wheels, engine blocks, and steering knuckles) or aluminum profiles for rail transit systems, calcium content must be strictly controlled—typically maintained at or below 0.05%. ...continued below. Should an abnormal calcium level be detected in a pre-furnace sample, a calculated amount of "Calcium Remover No. 2" can be rapidly introduced into the holding furnace. After a brief period of stirring, a new sample is taken for verification, enabling rapid corrective action and preventing the entire batch of molten aluminum from being scrapped.

**Preventing Typical Defects in Die Casting and Sand Casting Processes**
Excessive calcium significantly increases the tendency of aluminum alloys to stick to molds while simultaneously reducing melt fluidity, often leading to defects such as cold shuts, hot cracks, and surface tearing. Treating the melt with this product prior to mold filling effectively mitigates the risk of abnormally high surface tension in the molten metal. This improves the molten aluminum's ability to fill complex mold geometries, thereby reducing internal shrinkage porosity and hot cracking in castings, and boosting the yield rate for complex, thin-walled components.

**Periodic Cleaning of Melting Furnaces (Calcium Removal/Furnace Washing)**
In melting furnaces used for the continuous, long-term processing of calcium-containing scrap, calcium compounds gradually accumulate on the furnace walls or hearth. This accumulation can lead to passive contamination, causing the calcium levels in subsequent batches of fresh molten metal to exceed permissible limits. Periodically performing a "furnace washing" operation—utilizing this product in conjunction with mechanical stirring—effectively strips away and removes these calcium deposits, restoring the cleanliness of the melting environment and extending continuous production cycles.

**Flexible Application Across Melting Equipment of Varying Capacities**
Calcium Remover Flux 2# Multi Effect Cleaning Purifying Flux is supplied in convenient 5 kg bags, allowing for flexible, on-demand dosing directly at the production site. For instance, to remove 0.5 kg of calcium from a 500 kg furnace, one would use approximately 3.5–4 kg of the product (a partial bag may be used if the required amount is less than a full bag). Similarly, to remove 2 kg of calcium from a 3-ton furnace, one would use 14–16 kg (equivalent to 3 or 4 bags). This simple, intuitive dosing method eliminates the complications associated with controlling precise quantities when working with large-format packaging once it has been opened.
