Due to the advancement of science and technology, various industries have higher and higher demand for the quality of metal products, and more and more attention is paid to the smelting and processing technology of metal materials. Generally speaking, aluminum casting is the process of converting liquid aluminum into aluminum ingots, bars or other shapes, semi-finished products, by means of mixing, stirring, static setting, refining, acid slag, etc. Casting manufacturing is a very important process in the production of aluminum and aluminum alloy products. The quality of ingot products also affects the production and processing yield, product quality and performance of later profile products.

At present, the raw materials used by enterprises that manufacture aluminum strips in the market are mainly two kinds of pure aluminum ingots and recycled aluminum. As a very important industrial raw material, aluminum ingots are used in large quantities by many material production enterprises every day, and aluminum ingots are also the main factor affecting the production cost of such enterprises. The production of aluminum profiles begins with aluminum ingots, which are dissolved, cast, and homogenized into aluminum rods. Therefore, the price of aluminum rods is correspondingly higher than that of aluminum ingots. Both aluminum ingots and aluminum rods are the main materials for the production of aluminum profiles. . The aluminum rod becomes a profile after extrusion, and then after oxidation, electrophoresis, spraying and other process procedures, it becomes a profile that everyone sees in daily life.

The aluminum bar made of aluminum has many characteristics such as moisturizing, constant storage temperature, power saving and environmental protection, convenient assembly, and long service life, so it is widely used in cold storage. The pure aluminum ingot in the aluminum ingot factory is also called electrolytic aluminum and original ecological aluminum, which refers to the primary aluminum produced by the electrolytic cell. Therefore, the aluminum bar products produced with it can better ensure the cooling effect of the refrigerator. On the market, the price of pure aluminum ingots is much more expensive than recycled aluminum.
