Copper alloy antivacuum adding Zircomium engineering technology equipment and technological process thereof

Abstract

The invention discloses a device for non-vacuum zirconium doping engineering in a copper alloy and the process thereof. The device comprises an induction melting furnace (1), a seal mechanism (2), a casting tube (3), a protective cover (4) and a crystallizer (5). The seal mechanism (2) is fixed on one side of the upper part of the induction melting furnace (1) through bolts. The casting tube (3) is fixed at the bottom at the other side of the seal mechanism (2). The crystallizer (5) is inserted into the lower end of the casting tube (3) through the protective cover (4). The process includes the following steps: loading, sealing, melting, refining, argon gas introduction, Zr doping, casting and testing, wherein the casting step is implemented by using the furnace, the casting tube and the crystallizer.

Description

Technical field [0001] The invention relates to the technical field of non-ferrous metal materials and processing, in particular to a copper alloy non-vacuum zirconium-added engineering technical equipment and a process method thereof. Background technique [0002] Zirconium-containing copper products, which are added with zirconium and other elements to copper alloys, have rapidly increased demand in the fields of electronic materials, welding electrode materials, and crystallizer materials due to their excellent comprehensive properties such as electrical conductivity, thermal conductivity, and high-temperature softening resistance. In particular, Cu-Cr-Zr alloy materials are the most attractive high-strength and high-conductivity alloys, which are the focus of research and development by industrial countries in the world to meet the development of large-scale integrated circuits. The outstanding technical difficulty in the production of this type of alloy is to solve the ...

AI Technical Summary

Problems solved by technology

[0006] (1) Serious environmental pollution

Cast iron molds must be painted and baked. Generally, cast iron molds are smoked with benzene to form a layer of heat-resistant coating to insulate the corrosion of high temperature copper liquid on cast iron molds. Benzene is volatile, poisonous to the human body and causes serious pollution to the surrounding environment.

Although other coatings have been developed at present, due to problems such as difficulty in uniform coating, difficulty in baking and drying, and difficulty in storage of coatings, many companies mainly use the benzene fumigation method in actual production.

[0007] (2) Low yield rate

Mold casting must be fed at the end. The larger the size of the mold, the corresponding size of the insulation cap will also increase, and the geometric waste caused by the insulation cap will be more. The surface quality of the ingot produced by the cast iron mold is generally poor, and many enterprises deliberately design the size of the mold to be larger. , adopting ingot wagons to supply qualified billets also results in geometric waste; the surface of billets is prone to defects such as voids and inclusions, causing the entire ingot to be scrapped

[0008] (3) Low production efficiency

[0009] (4) The production operation is cumbersome

Every time the casting mold is used, it must be painted and effectively baked. It is also necessary to bake the insulation cap, mold pad and other tools and molds. Every time it is cast, it must be accurately positioned and placed in the furnace again. The series of supporting tools and molds that have been baked in advance , many production procedures

[0010] The production of foreign Cu-Cr-Zr alloy materials has begun to use new non-vacuum production technology, but due to factors such as foreign technology blockade and intellectual property protection, little is known about the non-vacuum production technology of foreign Cu-Cr-Zr alloy materials Few, and no relevant reports were found
