Process for producing rare earth copper alloy

Abstract

The invention relates to a process for producing a rare earth copper alloy. The process comprises the following steps: adding and refining an alloy element in a melting pot, and degassing by using a hexachloroethane degassing agent; standing for 50 minutes, then injecting into a second pot, adding rare earth, and then degassing and removing slag. The process particularly comprises the following steps: (1) heating and cleaning a melting furnace device; (2) weighing 1000 kg of copper ingots, and preheating; (3) after the copper ingots are melted and the temperature of the melting furnace is increased to 1100-1200 DEG C, adding manganese chloride, then increasing the temperature of the melting furnace to 1300-1400 DEG C, and installing a mechanical stirring device for stirring; (4) adding a fusing agent; and (5) degassing, and then manually removing the slag. The rare earth copper alloy produced through the process disclosed by the invention has excellent abrasion resistance and anti-extrusion capacity, is a high-quality choice of an automobile king pin bushing material, is simple in production process, and is easy to popularize, and the utilization ratio of rare earth resources is increased.

Description

technical field [0001] The invention relates to the technical field of production of new metal alloy materials, in particular to a production process of a rare earth copper alloy. Background technique [0002] With the rapid development of the global economy, the use of automobiles is increasing year by year, and the competition among major automobile manufacturers is becoming more and more intense. Therefore, the service life requirements for the hinge parts of automobiles are getting higher and higher. The service life is about one year, and the disassembly process of replacing the steering pin bushing is extremely cumbersome, and it increases the maintenance cost of the majority of truck users. Therefore, there is an urgent need for a new technology to improve the wear resistance of the materials used in the steering pin bushing, reduce maintenance costs and prolong the service life.
