The invention discloses a production process of semi-hard soft
copper belts. The process comprises a coarse rolling work procedure, an annealing work procedure, a middle rolling work procedure, an annealing work procedure, a fine rolling work procedure, a normal annealing work procedure, a cleaning work procedure, a bending pulling straightening work procedure, a
cutting work procedure and a packing work procedure. Compared with the prior art, the production process has the advantages that the normal annealing is adopted. Compared with the low-temperature annealing process, the production process has the advantages that soft
copper belt products can be obtained, in addition, the bending pulling straightening work procedure is added, the bending pulling straightening is mainly used for improving the belt form quality of hard belt materials, the process is equivalent to once rolling at an ultralow
processing rate, and the belt materials can generate certain plastic deformation after the bending pulling straightening, so the products are processed into the semi-hard soft state from the soft-state
processing, the product performance regulation is reached through controlling the elongation rate and the tension, the obtained
copper belt products have uniform performance, in addition, the belt form quality of products is greatly improved, the product grade is improved, and the use requirements of customers are met.
