With the improvement of technology requirements in all walks of life, the surface treatment technology of products has attracted more and more attention, and the shot blasting machine came into being under such a background. A large number of shot blasting machines have been put into the market, making the use of projectile materials more and more, and there are many types of projectile materials, such as cast steel shot, stainless steel shot, steel wire cut shot and steel wire abrasive shot, etc., so what are their respective characteristics? Next, let's take a look down with the editor, and let's learn about their respective characteristics.
1. Steel wire cut shot
Steel cut shot is cut to make steel cut shot. The ratio of length and diameter is equal, and the hardness and density are uniform. It is an ideal metal shot blasting material for shot blasting and shot peening strengthening. There are no pores, cracks, etc. in the shot, and the density is high. , Strong spraying power, widely used in aviation, automobile industry, foundry industry, steel structure manufacturing industry, etc.
2. Stainless steel shot
Stainless steel shot is divided into ball milled stainless steel shot and atomized stainless steel shot. Among them, the ball-milled stainless steel shot is exquisitely made by wire drawing, cutting, and rounding. The appearance is bright and rust-free, and it is cylindrical (cut shape, round cut). It is widely used in surface cleaning, deburring, strengthening and blasting treatment of copper, aluminum, zinc, stainless steel and other workpieces. It will have a matte effect on the processed workpieces, highlighting the characteristics of the metal's true color and no rust. The workpiece does not need to be pickled and derusted. The wear resistance of this type of steel shot is 3-5 times that of cast steel shot, which can reduce the production cost of the manufacturer. At present, this series of products are widely used in the strengthening process treatment of non-ferrous metal casting industry, automobile, motorcycle, shipbuilding, aviation, steel plate, steel cylinder, steel structure, metallurgical machinery and other fields.
Atomized stainless steel shot is refined by the atomization industry. It has a bright appearance, no rust, and is round. It is generally suitable for surface shot blasting of non-ferrous metal workpieces such as aluminum alloys and zinc alloys. It can show the true color and luster of metal materials. , will not cause rust and discoloration on the casting surface. The service life of the atomized stainless steel shot is long, and the wear on the equipment is relatively small. The surface of the workpiece after treatment is smooth and clean, and there is no need to pickle again.
