Short stage preparation technics of overlength copper alloy line staff

Abstract

The invention provides a preparation process for the short flow of an ultra-long copper alloy wire rod. The process includes the following steps: alloy melting, continuous casting, pulling, and a wire rod finished product, an atmosphere protective induction melting furnace is adopted to melt under the non-vacuum condition, the induction melting furnace is provided with a down-drawing, a horizontal, and an up-drawing continuous casting crystallizers which have different specifications, and the preparation is formed through continuously casting the wire rod. The invention can realize the expansion of a Cu-Cr-Zr alloy wire rod on the length through the down-drawing, horizontal, and up-drawing continuous casting, to meet the production requirement of the ultra-long Cu-Cr-Zr alloy wire rod; the protective atmosphere can protect oxidable elements, thereby obtaining Cu-Cr-Zr alloy wire rod materials which meet the requirement of alloying components, and produced wire rods uniformly are bright rods, the surface is not required to perform the scalping treatment. In addition, through changing the down-drawing, the horizontal, and the up-drawing continuous casting crystallizersw, continuous casting wire rods with various cross sections can be produced, and the rod material organization is better, thereby having the excellent plastic processing performance.

Description

technical field [0001] The invention relates to a short-process preparation process for an ultra-long copper alloy wire rod, in particular to a short-process preparation process for an ultra-long Cu-Cr-Zr alloy wire rod, and belongs to the technical field of nonferrous metal processing. Background technique [0002] Due to the high strength and electrical conductivity of Cu-Cr-Zr alloy, its rod-shaped wire products are widely used in electronics, electric power, automobile, light industry, transportation and other industries, especially the ultra-long Cu-Cr-Zr alloy wire rod The realization of production makes it more market application prospect. The short-process production method can realize energy saving, consumption reduction and environmental protection, and has excellent social benefits. Cu-Cr-Zr alloy wire rods, especially ultra-long wire rods produced by non-vacuum methods are typical high value-added copper alloy products. [0003] Cu-Cr-Zr alloy is very easy to o...

AI Technical Summary

Problems solved by technology

[0004] The traditional production process has the following problems: ① Vacuum smelting and casting consumes a lot of energy, low efficiency, and high production costs; ② Vacuum smelting and casting cannot achieve continuous production, and the size and specification of the ingot are limited. The produced Cu-Cr -Zr alloy wire rods are limited in length, and cannot produce ultra-long Cu-Cr-Zr alloy wire rods; ③There are many production processes and long production cycles, and at the same time, the yield of finished products is reduced due to many production processes
