Pyrothermic Slag-Aluminum Separation Flux is a high-efficiency aluminum ash treatment aid specifically designed for the aluminum smelting and recycled aluminum industries. Leveraging its unique pyrolysis reaction characteristics, this flux significantly promotes the rapid separation of molten aluminum and oxide slag during aluminum ash treatment. The recommended addition ratio is 0.2%-0.4% of the total aluminum ash or melt volume, but users can adjust the dosage flexibly according to actual on-site process requirements. During use, it is essential to ensure the system temperature is stable above 720℃, at which point the flux can be fully activated and achieve optimal separation efficiency. The product is packaged in standard 25 kg/bag sealed packaging, facilitating storage, transportation, and on-demand feeding. It is an ideal functional auxiliary material for improving aluminum recovery rates and reducing aluminum content in slag.
Main Advantages: Highly efficient aluminum recovery and significantly reduced residual aluminum in slag: In high-temperature environments above 720℃, this product can rapidly penetrate the aluminum ash layer, disrupting the encapsulation structure of aluminum and oxide films, causing fine aluminum droplets to efficiently aggregate and settle, significantly improving aluminum recovery rates and reducing metal loss.
Exothermic reaction enhances penetration: The formula exhibits pyrolysis and moderate heating characteristics, locally strengthening the thermal field and improving slag fluidity, making it easier to separate molten aluminum from viscous slag. It is particularly suitable for processing secondary aluminum ash with fluctuating aluminum content.
Flexible dosage and wide adaptability: The standard recommended dosage is 0.2%-0.4%, clearly marked "according to actual needs," allowing technicians to optimize the ratio based on the source of aluminum ash, compositional differences, and target recovery rate, avoiding waste or insufficient dosage.
Easy operation, environmentally friendly and slag-reducing: No additional toxic gases are generated during use, helping to reduce the amount of subsequent cold slag treatment and lowering solid waste emission pressure. The finished aluminum molten aluminum has higher purity, and the slag is loose and easily peeled off, making subsequent processing more convenient.
Standard packaging, precise feeding: The 25 kg/bag specification is compatible with most smelting workshop metering tools. The moisture-proof and sealed design ensures long-term storage stability of the product. It is ready to use upon opening, reducing on-site dust.
Product Applications: Extraction of metallic aluminum from aluminum ash: Primarily used in the hot aluminum ash treatment process in aluminum foundries, recycled aluminum enterprises, and aluminum processing workshops. Add this product at a ratio of 0.2%-0.4% to an aluminum ash mixer or ash-frying pot (temperature guaranteed >720℃), combined with mechanical stirring, to quickly achieve the separation effect of "aluminum liquid sinking and slag floating," directly extracting high-purity aluminum liquid.
High-temperature separation of aluminum and slag: Suitable for pretreatment before slag removal in aluminum smelting furnaces or for aluminum ash recovery after slag removal. Pyrothermic Slag-Aluminum Separation Flux effectively breaks down the alumina shell covering the surface of aluminum droplets, breaking the physical structure of "aluminum encasing slag, slag encasing aluminum," allowing the aluminum liquid to flow out in a concentrated manner, and the remaining dry slag to be easily removed.
Improving overall yield in recycled aluminum processes: For smelting processes using composite ingots, crushed aluminum scrap, etc., adding Pyrothermic Slag-Aluminum Separation Flux can optimize the slag composition, reduce aluminum entrainment caused by excessively thick slag layers, and is especially suitable for controlling the aluminum content in slag during continuous production operations, thereby reducing raw material costs.
When used with ash roasting machines or rotary kilns: Pyrothermic Slag-Aluminum Separation Flux is highly compatible with mechanical aluminum ash processing equipment. Under operating conditions above 720℃, it can shorten the single-furnace processing cycle, reduce energy consumption, and help factories achieve a more efficient closed loop for aluminum resource recycling.
