Method for improving component uniformity during casting production of C19210 copper alloy

The invention belongs to the technical field of continuous production of copper alloy strips, and particularly relates to a method for improving component uniformity during casting production of C19210 copper alloy, which comprises the following steps: firstly, screening conventional component C19400 offcut, conventional component TKA offcut and re-cast ingot offcut, mainly using C19400 and TKA head and slice old materials and re-cast ingots with specific weight and fixed components; in the smelting process of the C19210 copper alloy, the prepared conventional component C19400 rim charge, the prepared conventional component TKA rim charge, the prepared remelting ingot rim charge, the C19210 rim charge and electrolytic copper are put together according to the proportion, the components are qualified at a time after smelting is completed, and only secondary component fine adjustment of individual batches is conducted on small metal. According to the method, the problems that due to nonuniform and segregation of
