Process for preparing powder metallurgy material

Abstract

The invention belongs to the technical field of powder metallurgy, and particularly relates to a process for preparing a powder metallurgy material. The process comprises the following specific steps that S1, a rotating shaft is rotated through a large servo motor, and when the rotating shaft rotates, a circular plate and a stirrer are driven to rotate, so that the rotating circular plate moves a smelting box body to a position below a feeding hole, and a plurality of groups of materials are correspondingly put into a crucible; and S2, when the materials are put into the smelting box body, the materials in the crucible are molten through a first induction coil and a first magnet yoke until the materials in the crucible are changed into liquid, so that the different materials are separately molten, and after the materials are changed into the liquid, a rotating plate on a rotating shaft is rotated through a small servo motor. According to the process, alloy particles are prepared through a granulation structure, so that the alloy has the effect of being small in size, the rolling efficiency can be improved, and the quenching and tempering efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to a process for preparing powder metallurgy materials. Background technique [0002] Powder metallurgy is a process technology for preparing metal powder or using metal powder, or a mixture of metal powder and non-metal powder as raw materials, after forming and sintering, to manufacture metal materials, composite materials and various types of products, powder metallurgy method and production of ceramics There are similarities, all belong to powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving the problem of new materials. In the development of new materials Playing a pivotal role, the current powder metallurgy process mainly includes the following steps: powder preparation, molding, sintering...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the object of the present invention is to provide a process for the preparation of powder metallurgy materials by separate melting of different materials by means of a smelting structure, and preparation of granules by a granulation structure and quenching and tempering of the granules by a quenching structure and a tempering structure treatment, and then by rolling the treated particles, it can solve the problem that most of the powder metallurgy materials prepared by the above-mentioned existing process are of poor quality and the preparation time is long
