Embodiment 1

[0022] Such as figure 1 As shown, the preparation equipment for tungsten-copper alloy includes an electron beam melting furnace 1, an electron gun assembly 2 is arranged on the top of the electron beam melting furnace 1, a raw material placement mechanism 6 is arranged at the bottom, and a feeding mechanism 7 is arranged on the side wall. The discharge end of the feeding mechanism 7 is connected to the raw material placing mechanism 6 .

[0023] The electron gun assembly 2 includes an electron gun and a rotating seat on which the electron gun is installed. The electron gun is a cold-cathode electron gun with a maximum power of 600kw and a melting temperature of up to 10,000°C. The rotating seat can rotate within a certain range so that the electron gun can perform circular scanning. The raw material placing mechanism 6 is used to place the raw material, and a crucible can be used, and its position corresponds to that of the electron gun, so as to ensure that the electron beam ...

Embodiment 2

[0031] Such as figure 2 As shown, the preparation equipment for tungsten-copper alloy includes an electron beam melting furnace 1, two electron gun assemblies 2 are arranged on the top of the electron beam melting furnace 1, two raw material placement mechanisms 6 are arranged on the bottom, and two Feeding mechanism 7 , the discharge end of each feeding mechanism 7 is connected with a raw material placement mechanism 6 , and each raw material placement mechanism 6 is located below an electron gun assembly 2 . The structures and functions of the electron gun assembly 2, the raw material placing mechanism 6 and the feeding mechanism 7 are the same as those in the first embodiment.

[0032] When preparing copper-tungsten alloy, put the copper raw material and the tungsten raw material into the two raw material placement mechanisms 6 of the electron beam melting furnace 1 at the same time, and there is a certain distance between the two raw material placement mechanisms 6, so th...

Abstract

The invention provides a preparation method of a tungsten-copper alloy, which comprises the following steps: vacuumizing an electron beam smelting furnace, and emitting electron beams to a copper raw material by using an electron gun assembly to liquefy and evaporate copper to form copper steam; using the electron gun assembly to emit the electron beams to a tungsten raw material, liquefying and evaporating tungsten,and forming tungsten steam; and mixing the tungsten steam and the copper steam to obtain copper-tungsten mixed steam, and after rapid cooling, solidifying the copper-tungsten mixed steam into the copper-tungsten alloy. The invention further provides preparation equipment of the tungsten-copper alloy, the preparation equipment comprises the electron beam smelting furnace, the electron gun assembly is arranged at the top of the electron beam smelting furnace, a raw material placing mechanism is arranged at the bottom of the electron beam smelting furnace, a feeding mechanism is arranged on the side wall of the electron beam smelting furnace, and a discharging end of the feeding mechanism is connected with the raw material placing mechanism. The electron beam melting has purification and refining effects, so that the copper raw material and the tungsten raw material can be low-cost recycled materials, and the cost is reduced by more than 15% compared with that of only powder metallurgy.

Description

technical field [0001] The invention relates to the technical field of tungsten-copper alloy preparation, in particular to a preparation method and equipment for tungsten-copper alloy. Background technique [0002] Tungsten-copper alloy is an alloy composed of tungsten and copper, and the copper content of commonly used tungsten-copper alloy is 10% to 50%. Tungsten copper alloy has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At a very high temperature, such as above 3000°C, the copper in the alloy is liquefied and evaporated, absorbing a large amount of heat and reducing the surface temperature of the material. So this kind of material is also called metal sweating material. Since the melting points of tungsten and copper are different, the preparation efficiency is low and the cost is high. The present preparation methods include powder metallurgy method, injection molding method, copper oxide method, tungsten and moly...
