Abstract
The invention relates to a production method of a high-purity boron-copper alloy. The high-purity boron-copper alloy is produced from the following materials in parts by weight: 50-55 parts of boron carbide, 35-45 parts of metal copper and 0-30 parts of carbon-containing additive. The production method comprises the following steps: mixing the materials; and smelting in an electric melting way in a vacuum resistance furnace at the temperature of 2000-2400 DEG C for 4-5 hours to obtain the finished product, wherein the carbon-containing additive is charcoal, graphite, petroleum coke or any combination of charcoal, graphite and petroleum coke. The invention has the advantages of low production cost and environment conservation, and the high-purity boron-copper alloy produced by the method has stable quality and is difficult to volatilize and oxidize.
Description
Technical field
The present invention relates to the production method of high purity boron copper alloy.
Background technology
The high purity boron copper alloy is a reductor, be to improve solidity to corrosion, improve the important master alloy of intensity, be manufacturing self-melting alloy, high-temperature brazing alloy, amorphous soft magnetic alloy, non-crystalline state resistance alloy, be the core material of making equipment such as boron steel, engine, generator.At present, what adopted the home and abroad is that this chemical process of self-combustion process is produced the high purity boron copper alloy, this method is polluted greatly, safety coefficient is little, need the advanced person's of advanced Chemical Manufacture technology and assurance environmental requirement production unit, to improve production cost greatly undoubtedly, moreover according to said method there is unstable product quality in the product of Huo Deing, the shortcoming of volatile oxidation.
Summary of the invention
Technical problem to be solved by this invention is: the production method that the high purity boron copper alloy of the low and environmental protection of a kind of production cost is provided.
Technical solution of the present invention is: it is after norbide 50～55 weight parts, metallic copper 35～45 weight parts and carbon-contained additive 0～30 weight part are mixed, made in 4～5 hours by vacuum resistance furnace electrofuse smelting under 2000 ℃-2400 ℃ temperature, described carbon-contained additive is charcoal, graphite, refinery coke or its arbitrary combination.
Technique effect of the present invention is: it has the advantage of the low and environmental protection of production cost, adopts the high purity boron copper alloy steady quality of this method processing, not volatile oxidation.
