Embodiment Construction

[0024] Such as Figure 1 to Figure 5 as shown,

[0025] The principle is: use selected raw material scrap steel, add rare metals and alloys with the best ratio, smelt in an electric furnace, and transform it into steel wire through modern equipment production, and undergo multiple electric heat treatments, drawing, cutting shots, rounding passivation, automatic Screening, during the process of forming steel particles from liquid metal, its chemical composition and particle size are strictly controlled to ensure that its mechanical properties are suitable for various purposes. There is the most stringent quality management in each production link. The steel shot produced has a tight internal structure, is not easy to break, has a uniform particle size distribution, has appropriate hardness, strong impact resistance and long service life.

[0026] It is described in detail in conjunction with the technological process below:

Abstract

Provided is a high-hardness and long-service-life steel wire cut shot producing method and production line. The high-hardness and long-service-life steel wire cut shot producing method is characterized by comprising the following steps of coarsely drawing and annealing steel wires, finely draying the steel wires and cutting, rounding, passivating and sieving the steel wires. The steel wire cut shots produced in the method are high in hardness, the hardness of the steel wire cut shots can reach 58-60 HRC, the steel wire cut shots are low in broken rate and long in durability, and the durability is more than 4000 times. The producing method is high in processing speed and can meet the requirements of domestic shot blasting industries.

Description

technical field [0001] The invention relates to a production method of cut steel wire shot, in particular to a production method of cut steel wire shot with high hardness and long service life. Background technique [0002] At present, domestic metal abrasives for shot peening mainly include cast steel shot, steel wire cut shot, stainless steel shot and cast iron shot. The cast steel shot is cast, and shrinkage cavity or looseness is easy to form in the center of the cast steel shot, which reduces the performance of the cast steel shot; the hardness of the stainless steel cut shot is very low, and it can only process stainless steel and aluminum parts with low hardness. The Owen life of cast iron shot is the lowest, with an average of only about 600 times, and the pollution is serious, the production cost is high, and it is now facing elimination; the cut steel shot is made of steel wire, and the structure of the cut steel shot is very dense. Owen has a long life, high hard...
