The high-efficiency non-sodium refining agent has the functions of covering, removing slag, degassing, deterioration, and refinement, and can purify molten aluminum. Compared with ordinary refining agents, the amount of sodium-free refining agent is reduced by 40-60%. Because the aluminum content in the aluminum ash is reduced due to the thorough slag removal, the purity of the aluminum liquid is improved, and the ash output of the aluminum ash is reduced by 25-35%. Improve the recovery rate of secondary aluminum, reduce energy consumption and the cost of subsequent aluminum ash treatment.
The use of high-efficiency non-sodium refining agents without smoke reduces the environmental impact and improves the work intensity of workers. The molten aluminum impurity only needs to be added once, the operation is simple, there is no violent reaction during the reaction process of the molten aluminum, no black disgust, no irritating odor, compared with other molten aluminum solvents, the slag removal and degassing effect is good, which reduces the worker’s labor intensity, improve the working environment, increase work efficiency, because this product does not contain sodium ions, it is also suitable for use in high magnesium alloy cast aluminum alloy.
Because the non-sodium refining agent has the effect of deterioration and refinement, it can improve the organization and physical and mechanical properties of aluminum products after application, enhance the tensile strength of the product, stabilize the elongation, increase the surface brightness and product qualification rate. The scope of application is suitable for the smelting of deep-processed raw materials such as casting aluminum alloys, plates, rods, pipe rods, die castings, aluminum plates, strips, and foils.
The amount of non-sodium refining agent is 0.-0.20%, and the actual amount of the user can appropriately increase or decrease the melting amount according to the impurities in the aluminum water. When the temperature of the molten aluminum is more than 680°C, a nitrogen blowing device is used to blow the refining flux into the depth of the molten aluminum to cause a reaction, so that the bubbles will absorb hydrogen atoms during the floating process to achieve degassing, slag removal, and grain refinement purpose. Packing and storage 2kg or 5kg/bag, 20kg/carton. Ventilated and dry, the bag must be used immediately after opening, and it must be sealed if it is not used up. The shelf life is 12 months from the date of production. All unpacked products must be used up within 4 hours. If the packaging is intact, even if it exceeds 12 months, as long as there is no agglomeration and moisture, the effect will not be affected.
