Manufacturing method of low-tin brass strip for replacing phosphor copper

The invention discloses a manufacturing method of a low-tin brass strip for replacing phosphor copper, which comprises the following steps: (1) melting: putting a low-tin brass strip raw material into melting equipment for melting, and condensing molten steel into a blank through a crystallizer; (2) semi-continuous casting: carrying out semi-continuous casting work on the blank-formed steel through a blank drawing machine; (3) sawing: sawing the steel subjected to semi-continuous casting through a sawing machine; (4) hot rolling: performing hot rolling work on the sawed steel through hot rolling equipment; and (5) intermediate annealing, wherein the hot-rolled steel is subjected to primary annealing work through annealing equipment. According to the manufacturing method of the low-tin brass strip for replacing the phosphor copper, the manufacturing method of the phosphor copper is replaced by the manufacturing method of the low-tin brass strip, so that the strength and hardness of the copper strip are effecti
