Casting process description
The aluminum ingot casting process uses aluminum liquid to inject into the mold. After cooling to form the billet and taking it out, the injection process is the key step for the quality of the product. The casting process is also a physical process in which liquid aluminum crystallizes into solid aluminum. The technological process of casting aluminum ingot is as follows:
Discharging, slagging, weighing, batching, charging, refining, casting, remelting aluminum ingot, finished product inspection, finished product weighing, warehousing.
Aluminum discharging, slag raking, Jining, batching, charging, refining, casting, alloy ingot, casting alloy ingot, finished product inspection, Jining of finished product, warehousing.
The common casting methods are continuous casting and vertical semi continuous casting.
Production process
The production of aluminum ingot is composed of bauxite mining, alumina production, aluminum electrolysis and other production links.
The bauxite is extracted first, the bauxite powder is produced by water washing, grinding and other processes, and then the aluminum oxide is obtained by four complex processes such as roasting. There are three types of bauxite used to produce aluminum oxide: gibbsite, diaspore and boehmite.Due to the different characteristics of three kinds of bauxite, different alumina production enterprises adopt different production processes, mainly including Bayer process, alkali lime sintering process and Bayer sintering combined process. Generally, high-grade bauxite is produced by Bayer process, while medium and low-grade bauxite is produced by combined process or sintering process. Because of its simple process and low energy consumption, Bayer process has become the most important method in alumina production. Its output accounts for about 95% of the total alumina production in the world.
Aluminum oxide in the role of strong current, electrolytic aluminum metal, this process is called electrolytic aluminum
