AI Technical Summary
Technical Problem
In traditional ingot casting processes, phosphorus precipitation from molten copper leads to segregation defects on the ingot surface. Existing methods are inefficient, costly, and result in poor working conditions.
Method used
By detecting and adjusting the composition of molten copper, and employing a pull-stop casting method, the crystallization process of the melt is controlled, including the pulling and stopping actions, combined with a protective cover to isolate air contact, thus forming a high-quality ingot.
Benefits of technology
It effectively inhibits phosphorus precipitation, improves the surface quality of ingots, reduces subsequent processing problems, saves costs, improves the working environment, and increases product qualification rate.
