Annealing furnace and annealing process for copper wire production

Abstract

The invention belongs to the technical field of annealing furnaces, in particular to an annealing furnace for copper wire production, which seriously affects production due to imperfect design of existing annealing furnaces, imperfect design of steam protection, imperfect design of anti-oxidant cooling circulating water devices, etc. For the problems of efficiency and quality, the following scheme is proposed now, which includes the annealing furnace body, cooling water tank, copper wire and antioxidant water tank, and it also discloses the annealing process. In the present invention, the inlet of the annealing furnace body is lowered and the outlet is slightly higher through the backing plate, so that the angle of passing the wire is parallel to the wire, the resistance is small, and the interruption of the copper wire during production is reduced, and the steam at the inlet of the furnace tube is used to protect the copper wire through the steam assembly. That is, there is steam at the entrance, and the air cannot enter, which improves the appearance of the copper wire. The antioxidant cooling water is circulated and filtered through the anti-oxidation component and the cooling component to reduce the surface dirt of the copper wire. Finally, it is dried by the drying component, which improves the production efficiency and Product qualification rate, reduce production costs.

Description

technical field [0001] The invention relates to the technical field of annealing furnaces, in particular to an annealing furnace and an annealing process for copper wire production. Background technique [0002] Heat treatment furnaces are divided into annealing furnaces, quenching furnaces, tempering furnaces, normalizing furnaces, and quenching and tempering furnaces. They are mainly used for annealing of large carbon steel and alloy steel parts; tempering of surface quenched parts; heat treatment processes such as stress relief annealing and aging of weldments. Heating methods include electric heating, oil, gas, coal, and hot air circulation. Annealing furnace is a new type of heat exchange equipment. The annealing furnace is an energy-saving periodic operation furnace with a super energy-saving structure and a fiber structure, saving 60% of electricity.

Problems solved by technology

[0003] For the pure copper fine 0.03-0.05mm production process currently on the market, the copper wire passes through the existing production process (imperfect design of annealing furnace, imperfect design of steam protection, imperfect design of anti-oxidant cooling circulating water device, etc.), which seriously affects Production efficiency and quality are no longer suitable for the production process requirements of the copper industry, so we propose an annealing furnace and annealing process for copper wire production to solve the above-mentioned problems
