It was learned from relevant parties that the oxygen-free copper rod production line independently developed by China has been officially put into production in the Zhengzhou Hi-tech Development Zone. This can produce an oxygen-free copper rod production line with a diameter of 8mm, producing high-quality copper rods at a traction speed of 3.2m/min. The traction speed is higher than that of similar international equipment. The performance of the products meets or exceeds that of similar international products. Level. Experts believe that the student
