Continuous production device and manufacturing process of arc-striking-preventing alloy copper

Abstract

The invention discloses a continuous production device for arc-striking-preventing alloy copper and a manufacturing process of the arc-striking-preventing alloy copper. The continuous production device comprises a melting furnace, a heat preservation furnace, an electromagnetic stirring device, a continuous extruding machine and a drawing machine which are sequentially arranged. The electromagnetic stirring device comprises a shell, an electromagnetic inductor and a cooling water path, the electromagnetic inductor is arranged outside the shell, one end of the shell is connected with the cooling water path, the cooling water path comprises a cooling water inlet and a cooling water return port, the cooling water inlet is connected with the lower end of the shell, and the cooling water returnport is connected with the upper end of the shell. By applying an electromagnetic stirrer, continuous production of a tellurium-copper rod is achieved, grains of the smelted copper rod are refined, the surface of the copper rod is smooth, continuous production of tellurium-copper products is achieved, the stability of the tellurium-copper products in the production process is guaranteed, the production cost of the tellurium-copper products is greatly reduced, and the product quality and the production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of production of copper alloys, in particular to a continuous production device and a production process of arc-proof alloy copper. Background technique [0002] With the country's vigorous promotion of new energy vehicles in recent years and the vigorous construction of charging piles, there are new indicators for the contact materials of charging piles, such as arc resistance, service life and safety performance. Since 2010, tellurium copper due to its excellent electrical The characteristics of performance and easy processing have been successfully applied in the field of high-current connectors for new energy vehicles. [0003] Arc-resistant tellurium-copper alloys are also widely used in precision electronic and electrical components that require high conductivity, high conductivity, and corrosion resistance, advanced electromechanical parts, forgings and thread cutting parts, plumbing fittings, electri...

AI Technical Summary

Problems solved by technology

[0004] Most of the techniques used in the prior art use down-drawn semi-continuous casting of tellurium copper ingots for the production of tellurium copper products. The cross-section of the produced copper alloy is dendrite, which is easily broken by extrusion during the subsequent extrusion process. Therefore, the existing High technical efficiency, high cost and low yield, unable to achieve continuous production
