Steel wire pellet heat treatment is an important process in the production of steel wire ropes, and few merchants or manufacturers explain to customers the process characteristics of heat treatment and its impact on the quality of steel wire ropes. In order to help everyone better understand and use steel wire cutting pellets, the following provides a detailed introduction to the heat treatment process of steel wire cutting pellets.
The purpose of steel wire pellet heat treatment is to regain favorable conditions for cold drawing after heat treatment, that is, after cold drawing, the molecular structure of the wire or steel pellet changes. Although the strength increases, it is more prone to brittle fracture, and after reaching a certain degree, it cannot be pulled smoothly and may break instead. After heat treatment, the internal structure can be restored again, making it easy to stretch again, less prone to fracture, and able to achieve the required strength.
The entire process of cutting steel wire shot is completed by a shot blasting machine, which is called shot blasting. The editor has compiled the functions of steel wire shot blasting, as follows:
Shot blasting is the use of high-speed rotating impellers to throw small steel wires or iron balls, which collide with the surface of the part at high speed, thereby removing the oxide layer on the surface of the part. Steel wire shot blasting cutting or high-speed impact of iron balls on the surface of parts can cause lattice distortion and increase surface hardness, which is a method of cleaning the surface of parts. Shot blasting is commonly used to clean the surface of castings or strengthen the surface of parts.
Steel wire is shot blasted and cut on the surface of the workpiece to achieve a certain roughness, making the workpiece beautiful, or converting the welding tensile stress of the workpiece into compressive stress, thereby improving the service life of the workpiece.
Reduce blade and impeller wear, with a dull and angular appearance. At the beginning of use, the hardness is relatively low (around HRC40), but after several collisions, it gradually becomes circular and becomes thicker with high hardness (above HRC50). After the impact and fragmentation of white iron pellets (around HRC55), there is significant wear on the blades and impellers, while steel wire pellets become rounder and less worn on the blades and impellers.
Reduce dust pollution and alleviate labor for workers. Secondly, the economic benefits are enormous. It has the advantages of good toughness, high strength, and no breakage. According to the manufacturer of steel wire cutting pellets, its service life is more than 15 times that of cast iron pellets.
Improving the quality of cleaning is due to the fact that the steel wire cutting pellets do not break and have a relatively high impact force, resulting in good cleaning effect and high quality of the workpiece.

The above is the heat treatment work for steel wire cutting pellets. Its heat treatment can eliminate the work hardening in the previous cold drawing process, which is conducive to continuing cold drawing and making the hot-rolled wire rod have a structure suitable for drawing, and can be drawn normally. It has a special structure and good performance after cold drawing.
