  If the steel grit is too soft, it will reduce the cleaning speed and work efficiency. During the sandblasting process, too soft steel grit cannot produce suitable residual stress, and the force of low hardness sand cannot be compensated by increasing the impact time. If the hardness is too high, it will produce unsatisfactory surface morphology, increase the chance of broken sand, make the consumption too high, cause greater wear and tear on equipment, and increase equipment maintenance costs, so proper hardness is also very important. The carbon content should be moderate, silicon and manganese add strength and hardness to the steel grit, so it should be as high as possible. Sulfur and phosphorus are harmful elements, which can easily lead to the brittleness of steel grit and cause premature fracture, so the content of sulfur and phosphorus should be reduced as much as possible.

  The use of steel grit: 1. As a metallurgical deoxidizer and high temperature resistant material; 2. It can also be used for polishing and grinding of hardware, glass, gems, jade, etc. Silicon carbide mainly has four major application areas, namely: functional ceramics, advanced refractories, abrasives and metallurgical raw materials. Coarse silicon carbide has been supplied in large quantities, so it cannot be regarded as a new technical product, and the application of nano-scale silicon carbide powder with extremely high technical content cannot form economies of scale in a short period of time; 3. As an abrasive, it can be used to make abrasives Tools, such as grinding wheels, oil stones, grinding heads, sand bricks, etc. ; 4. High-purity single crystal, which can be used to make semiconductors and silicon carbide fibers.

  Steel grit is widely used in the pretreatment of steel workpieces before painting. In this process, the most widely used method is a sandblasting room with a recovery device. The angular shape and associated hardness of the grit allow for quick cleaning and efficient recovery. Steel grit is also widely used in the sand cleaning process of castings. Sometimes, when the workpiece temperature is too high, foundry sand can become embedded in the casting, which exceeds the cleaning ability of steel shot. At this time, only steel grit can be used.

  Steel sand is a new type of metal composite material. It is made of pure natural iron ore, and the main component is iron oxide. High temperature and other characteristics, iron sand is used in engineering construction to make iron sand concrete wear-resistant layer or iron sand cement mortar wear-resistant layer, its tensile strength, split compressive strength, friction resistance and other aspects are better than iron nail cement mortar wear-resistant. Steel sand is not only cheap in construction cost, but also simple in construction, and its impact strength and ductility are also very good. Iron and steel sand is mainly used in construction, such as the construction of medium mines and coal washing mines: wear-resistant layers in the inner cavities of various coal mines, Buchner funnels, launders, etc.; wear-resistant layers on the surfaces of coal pillars and coal beams; steel and coking infrastructure : Wear-resistant layer, such as mining tank, coal pit, coke tank, Buchner funnel; thermal power station infrastructure; water conservancy and hydropower engineering infrastructure; metallurgical industry, chemical plant infrastructure and its wear-resistant layer, such as various mineral processing plants and Buchner funnels, funnels and launders in chemical plants.
