An oxygen-free copper rod

Abstract

The invention discloses an oxygen-free copper rod, which includes a rod body, which is continuously rotated and twisted during the process of upward continuous casting, and the two sides of the rod body are covered with a first protective sleeve and a second protective sleeve. The two ends of the abutting side of the first protective sleeve and the second protective sleeve are respectively fixedly connected with a first connecting edge and a second connecting edge, and the side of the first connecting edge facing the second connecting edge is fixedly connected with a connecting rod, so There are a plurality of connecting rods, and the plurality of connecting rods are arranged at equal intervals. By setting the first protective sleeve and the second protective sleeve, the first protective sleeve and the second protective sleeve will wrap the rod body and play a protective role on the rod body, so that The rod body will not be worn when moving and transporting, and the bending degree of the rod body is limited by the shuttle-shaped notches on the outside of the first protective cover and the second protective cover, which facilitates the coiling of the rod body and reduces internal damage caused by excessive bending of the rod body, ensuring The quality of the rod body is stable, which is convenient for subsequent wire drawing processing.

Description

technical field [0001] The invention relates to the technical field of oxygen-free copper rods, in particular to an oxygen-free copper rod. Background technique [0002] Oxygen-free copper rod as the main material of the cable core is currently divided into low-oxygen copper rod for continuous casting and rolling and oxygen-free copper rod for upward continuous casting. The quantity and appearance are different. The copper rod produced by Shangyin has an oxygen content below 20ppm, which is called oxygen-free copper rod. Copper rods produced by continuous casting and rolling are hot-rolled under protected conditions. The oxygen content is in the range of 200-500ppm, but sometimes it is as high as 700ppm or more. Generally, the copper produced by this method is bright in appearance, commonly known as bright rods. [0003] After the oxygen-free copper rod is produced through a series of process steps, it will not be directly processed into the rod shape of the cable, but the ...
