Embodiment approach 1

[0007] The production method of the high-purity boron-copper alloy of this embodiment is to mix 50-55 parts by weight of boron carbide, 35-45 parts by weight of metal copper and 0-30 parts by weight of carbon-containing additives, and then pass through a vacuum resistance furnace at 2000 ° C to 2400 ° C. It is prepared by electric melting and smelting at a temperature of ℃ for 4 to 5 hours. The carbon-containing additive is charcoal, graphite, petroleum coke or any combination thereof.

Embodiment approach 2

[0009] The production method of the high-purity boron-copper alloy of the present embodiment is to mix 50-55 parts by weight of boron carbide, 35-45 parts by weight of metallic copper, and 0-15 parts by weight of charcoal and / or graphite, and then pass through a vacuum resistance furnace at 2000 ° C. It is produced by electromelting at -2400°C for 4 to 5 hours.

Embodiment approach 3

[0011] The production method of the high-purity boron-copper alloy of this embodiment is to mix 50-55 parts by weight of boron carbide, 35-45 parts by weight of metal copper and 0-30 parts by weight of petroleum coke, and then heat the mixture in a vacuum resistance furnace at 2000°C-2400°C.

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 [0001] The invention relates to a production method of high-purity boron-copper alloy. Background technique [0002] High-purity boron-copper alloy is a deoxidizer, an important intermediate alloy for improving corrosion resistance and strength, and is used for the manufacture of self-fluxing alloys, high-temperature brazing alloys, amorphous soft magnetic alloys, amorphous resistance alloys, and boron alloys. Core materials for steel, engines, generators and other equipment. At present, the self-propagating combustion method is used at home and abroad to produce high-purity boron-copper alloys. This method has large pollution and low safety factor, and requires advanced chemical production technology and advanced production equipment to ensure environmental protection. Undoubtedly Will greatly increase production cost, moreover, there is unstable product quality in the product that obtains by this method, the shortcoming of easy volatilization oxidation. ...
