Problems solved by technology

[0003] The purpose of the present invention is aimed at the problems existing in the background technology: the contact surface of the connecting end of the existing copper rod is single, and the copper rod cannot be connected stably and effectively, so there will be a situation where the joint is detached, which will affect the normal use of the copper rod; The quality of waste miscellaneous copper treatment is low, so the performance of the prepared copper rod is also relatively poor. A high-quality low-oxygen copper rod and its preparation method are proposed

Abstract

The invention belongs to the technical field of copper rod preparation and relates to a high-quality low-oxygen copper rod and a preparation method thereof. The invention mainly aims at the problems that an existing copper rod is poor in connection stability, complex in preparation process, high in cost, low in quality and the like. According to the technical schemes, the high-quality low-oxygen copper rod includes a copper rod body, a connecting groove is formed in a center shaft at one end of the copper rod body, and a connecting column is arranged at one end of the copper rod body. The invention further provides a preparation method of the high-quality low-oxygen copper rod. The preparation method comprises the following steps that: 1, raw materials are treated; 2, c copper liquid is casted and crystallized; 3,machining a copper casting blank; and 4, a low-oxygen copper rod is obtained. According to the prepared low-oxygen copper rod connector, the connecting face is enlarged, the connecting stability of the copper rod is improved, the conductivity and tensile strength of the low-oxygen copper rod are improved, the oxygen content in the copper rod is reduced, the tensile strength and the conductivity of the low-oxygen copper rod are improved, waste copper is utilized, the production cost is reduced, resources are saved, and the low-oxygen copper rod is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of copper rod preparation, in particular to a high-quality low-oxygen copper rod and a preparation method thereof. Background technique [0002] Low-oxygen copper rods refer to copper rods with an oxygen content of 200 (175)-400 (450) ppm. Generally, when drawing copper wires with a diameter > 1mm, the advantages of low-oxygen copper rods are more obvious. With the development of the electrical industry, the demand for materials such as cables and wires and the purity requirements are getting higher and higher. Low-oxygen / oxygen-free copper rods are widely used to guide electrical cables, especially low-oxygen copper rods with a diameter of 8mm. Its high purity, low oxygen content, and less impurities are favored by the market. The production of existing low-oxygen copper rods mainly adopts the continuous casting and rolling process. After the raw copper is melted, oxidized, reduced, and copper is produc...
