Manufacturing process for green harmless precise wires used for household appliances

Abstract

The invention relates to a manufacturing process for green harmless precise wires used for household appliances. The manufacturing process comprises the following steps of S1, preparing an electrolytic cathode copper plate; S2, loading the electrolytic cathode copper plate to a shaft furnace for smelting so as to prepare copper liquid; and S3, filtering slag of the copper liquid is drained througha slag box and then guiding the filtered copper liquid to a holding furnace for holding so as to keep the copper liquid in a liquid state The manufacturing process has the beneficial effects that: 1,through the process, grain crystallization of a product parent material is better controlled, and crystallized grains are thoroughly crushed so as to achieve better extension performance; 2, harmfulimpurities in the copper liquid are removed to reduce the content of the impurities in crystals of a copper billet, and a high-precision spectrometer is employed to detect the component of a copper bar so as to ensure the demands of high voltage and high current; and 3, generation of copper powder is strictly controlled on the product parent material from a blank material to a rolling and calendering process, and the content of the copper powder on the surface of the copper bar is reduced by cleaning.

Description

Technical field: [0001] The invention relates to the field of bare copper wires, in particular to a manufacturing process of precision wires for green and harmless household appliances. Background technique: [0002] In recent years, my country's wire and cable industry has developed rapidly and has become the second largest industry in the machinery industry after the automobile industry. It is an indispensable main supporting raw material for products such as motors, electrical appliances, household appliances, electronics, communications and transportation. It has made an important contribution to the development of the national economy and is known as the "vessel" and "nerve" of the national economy. At present, my country has become a big country in the production and use of cables, and its production and sales volume ranks first in the world. The sales and consumption of its main raw material copper have also surpassed that of the United States and Japan. Electromagnet...
