Steel grit has the best performance among current metal abrasives. It is mainly used for sand cleaning of large and medium-sized castings, removal of oxide scale from forgings and heat-treated parts, and rust removal and surface strengthening of steel plates, steel sections and steel components.
Steel grit is made from high-carbon cast steel shot by crushing it into sand particles, and then tempered into three hardnesses (GH, GL, GP) to suit different needs. The processed steel sand is sorted by a screen into 10 grades that comply with SAE standards to meet the needs of sandblasting. Products of different sizes and hardness are used in different situations, such as drum engraving, granite cutting, etc. The raw material of steel grit is scrap steel of high carbon steel or alloy steel. Steel grit application range:
1. As metallurgical deoxidizer and high temperature resistant material.
2. It can also be used for polishing and grinding hardware, glass, gemstones, jade, etc. Silicon carbide has four main application areas, namely: functional ceramics, advanced refractory materials, abrasives and metallurgical raw materials. At present, silicon carbide rough materials can be supplied in large quantities and cannot be regarded as high-tech products. However, the application of nano-scale silicon carbide powder with extremely high technical content cannot form economies of scale in a short time.
3. As an abrasive, it can be used to make abrasive tools, such as grinding wheels, whetstones, grinding heads, sand tiles, etc.
4. High-purity single crystal can be used to manufacture semiconductors, silicon carbide fibers.
