In the process of aluminum smelting and recovery, due to the impurities or insufficient reactants contained in the raw materials, as well as the oxidation and reduction reaction during the melting process, will produce insoluble impurities in aluminum liquid, that is, aluminum slag, these impurities will float on the surface of aluminum liquid, of which aluminum content accounts for more than 60%, so, It is necessary to use dross press, sow mold, dross pan, skim pot and other equipment to effectively improve the utilization rate of resources to reduce waste.
● Dross press is a very important equipment for aluminum slag treatment. Aluminum slag usually contains a lot of metal aluminum, but mixed with oxides and impurities, the traditional manual treatment method will cause a lot of aluminum loss. The principle of Dross Press is to extrude the metal aluminum in the aluminum slag through pressure, so as to separate more pure aluminum, which not only improves the recovery rate of aluminum, but also reduces the difficulty of follow-up treatment.
The operation of dross press is simple, according to the type of aluminum slag to choose the mode, the slag tray with hot aluminum slag into the slag press, through the mechanical force of the slag press metal aluminum and residue separation, the treated residue usually contains a small amount of aluminum, can be used for secondary recovery using rotary furnace and similar equipment.
● sow mold is used to collect liquid aluminum and form aluminum ingots, which are usually transported or stored over long distances to facilitate subsequent reprocessing or sales. Sow mold is available in different sizes for casting needs.
In the aluminum slag treatment process, after melting and degassing treatment, the liquid aluminum is poured into the sow mold, and after cooling, the aluminum ingots can be removed from the mold for quality inspection and treatment.
● Dross pan is a special container for collecting and transporting aluminum slag. During the aluminum smelting process, there will be scum on the surface, and it is necessary to remove the aluminum slag from the furnace and screen out the slag and aluminum.
Dross pan is usually made of high-temperature resistant materials and is designed to facilitate the collection and dumping of aluminum slag, allowing for the convenience of using forklifts to transport aluminum slag to a slag press or other processing equipment.
The dross press, sow mold and dross pan are very important equipment in the aluminum slag recycling process and are an efficient aluminum recycling system. Increase aluminum recovery with Dross Press, Sow Mold stores liquid aluminum and casts it into ingots, and dross pan collects and treats aluminum slag. The use of equipment can not improve production efficiency, but also can maximize the recovery of aluminum, effectively reduce the smelter's operating costs, but also reduce environmental pollution, reasonable and effective use can bring more economic benefits.
