Aluminum Smelting Process controlled for high-quality castings
The smelting of aluminum alloy is a very important process in the production of castings. Years of production experience has proved that the smelting process is not strictly controlled, and the castings are prone to pinholes, oxidized slag inclusions, shrinkage and other defects that directly affect the quality of the castings.

Smelting is a process of applying heat to ore in order to extract a base metal. [1] It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag ...
