Method for producing copper rod and copper rod wiredrawing device

Abstract

The invention discloses a method for producing a copper rod. The method comprises the following steps of 1) in the copper melting working procedure, melting a copper plate into molten copper; 2) in the casting rod working procedure, casting the molten copper on the surface of a core rod to generate a casting rod; 3) in the hot rolling working procedure, carrying out hot rolling treatment on the cooled casting rod to generate a copper rod; and 4) in the winding working procedure, winding the copper rod into a ring. The casting rod working procedure comprises copper rod wiredrawing operation, wherein the copper rod is drawn to become a core rod by adopting the copper rod wiredrawing device. Heat on one side of a wiredrawing furnace is transferred into a winch through circulating helium gas,and meanwhile, the winch is cooled by using cooling oil. The method solves the problems that in the prior art, cooling water is used for directly cooling a winch, a high-temperature copper rod entersthe winch, the temperature difference between the copper rod and the winch is too large, the copper rod shrinks rapidly, stress is easy to generate, and the final quality is influenced.

Description

technical field [0001] The invention relates to the field of copper rod production, in particular to a method for producing copper rods and a copper rod wire drawing device. Background technique [0002] In the production process of preparing copper rods by the dip coating method, it is necessary to wire-draw and peel the copper rods to produce qualified copper rods used as seed rods in the casting rod step. The peeling device is used to remove the oxide layer on the surface of the copper rod. Because the copper rod is soft, it is difficult to achieve the required surface finish after peeling the copper rod directly. Therefore, a wire drawing machine is required to draw the copper rod before peeling to improve The surface hardness of the copper rod facilitates the completion of the peeling operation. However, due to the increase in the running speed of the wire drawing machine in recent years, a large part of the heat generated during the wire drawing process is brought to ...

Problems solved by technology

[0003] In view of the above problems, the present invention proposes a method for producing copper rods, which solves the problem that the existing equipment directly cools the capstan with cooling water, and the high-temperature copper rod enters the low-temperature capstan. The temperature difference between the two is too large, and the copper rod shrinks rapidly. , it is easy to produce stress and affect the final quality; in addition, if the cooling effect of the winch is poor, the high-temperature copper rod in the winch will also enter the air, and the copper rod will shrink rapidly due to the large temperature difference, resulting in the problem of stress
