Description

technical field

[0001] The invention relates to the technical field of aluminum rod melting and casting, in particular to an aluminum rod melting and casting process. Background technique

[0002] In the past 20 years, with the rapid development of the construction industry, my country's civil construction aluminum profile industry has grown from scratch, and has advanced rapidly from weak to strong. So far, Guangdong Province's construction aluminum profile products have accounted for about two-thirds of the country's total. The production capacity of aluminum profiles exceeds the needs of the society. How to improve product quality and reduce costs is the key to winning market competition.

[0003] Aluminum rod melting and casting includes melting, purification, impurity removal, degassing, slag removal and casting process. The main process is:

[0004] Ingredients: According to the specific alloy grades that need to be produced, calculate the addition amount of various ...
