A kind of copper rod production method

Abstract

The invention discloses a copper rod hot rolling system which comprises hot rolling machines provided with rollers. The copper rod hot rolling system further comprises at least two installation boxes provided with installation ends, wherein the installation boxes are installed in sequence, and every two installation boxes are fixedly connected with each other through the installation ends. Each installation box is provided with at least four hot rolling machines in sequence, wherein the number of the hot rolling machines is an even number. The minimum distance between the roller of one hot rolling machine in one installation box and the roller of one hot rolling machine in another installation box adjacent to the one installation box is greater than the distance between the rollers of the two hot rolling machines in the same installation box. The invention provides a copper rod production method. The copper rod production method comprises the following steps that copper smelting is performed, wherein electrolytic copper boards are smelted into molten copper; rod casting is performed, wherein the molten copper is cast on the surfaces of core rods to form cast rods; cooling is performed, wherein the cast rods are cooled; hot rolling is performed, wherein hot rolling is carried out on the cooled cast rods through the copper rod hot rolling system to form copper rods; winding is performed, wherein the copper rods are wound into rolls.

Description

Technical field [0001] The invention relates to the technical field of copper rod production, in particular to a copper rod production method. Background technique [0002] Copper wire rod is a necessary blank for the production of copper wire such as wire and cable, enameled wire, electronic wire, etc., and copper wire is one of the important basic materials for electronics, electrical and communications industries. [0003] The production of oxygen-free copper rod by dip coating method is to smelt the copper plate into copper water, use the ability of cold copper rod to absorb heat, and use a thinner cold pure copper core rod (or seed rod), which can maintain certain The liquid level of the copper pool makes the copper water and the copper on the surface of the moving core rod fuse together, and gradually solidify and combine to form a thicker cast rod, and then cool, hot-roll, and wind into a circle, thereby producing electrical Bright oxygen-free copper rod. [0004] In the cop...

Problems solved by technology

In order to improve production efficiency, the number of hot-rolling mills can be increased to expand the specifications of the hot-rolling mills. When the number of hot-rolling mills is large, it will be installed sequentially in this way, which will take a long time and is not convenient for the installation of the hot-rolling mills.
