Production method of zinc base alloy thin-wall pipe

Abstract

The invention relates to a production method of a zinc base alloy thin-wall pipe, comprising steps of: (1) induction-heating a semi-continuous casting ingot of zinc alloy, and hot-extruding by a split-flow combination die to obtain a pipe blank which is close to finished product in size; (2) performing cold machining to obtain the thin-wall pipe; (3) cleaning and heat-treating; and (4) and then straightening to obtain the finished pipe. The invention provides a novel processing method for zinc base alloy thin-wall pipe, which has the advantages of short process, low cost,high production efficiency and high additional value in the produced zinc base alloy thin-wall pipe; and the processing technology of the zinc base alloy thin-wall pipe provided by the invention is suitable for mass production, and the produced zinc base alloy thin-wall pipe can substitute part of brass pipes, thus helping to solving the problem of scant brass resource in our country, and having obvious economic benefit and social benefit.

Description

technical field

[0001] The invention relates to a preparation method of a zinc-based alloy thin-walled pipe, belonging to the field of nonferrous metal processing and forming. Background technique

[0002] With the popularization of copper applications, copper resources are in short supply worldwide, and high-performance zinc alloy materials have the characteristics of light specific gravity, moderate strength, high hardness and low cost, and are known as new materials in the 21st century. Its strength, hardness, friction and other properties are similar to those of copper alloys. Therefore, research and development of new zinc alloys, replacing expensive copper with cheap zinc, has significant economic and social benefits, and is also the most effective way to alleviate the shortage of copper resources in China. Promising solution. A search of prior art documents found that there are few patents related to the preparation of zinc-based alloy thin-walled pipes.
