  Iron cast steel grit this product is a kind of local unique natural iron ore, the main component is iron oxide,cast steel grit is widely used, the effect is ideal. It is not only wear-resistant, compression resistant, impact resistant, but also has the properties of moisture resistance, acid and alkali corrosion resistance, high temperature resistance and so on. The cast steel grit is the preferred material for sand blasting, and is also an ideal new wear-resistant material for building materials. In the construction, the cast steel grit is used to make the wear-resistant layer of iron cast steel grit concrete or iron cast steel grit mortar. Its compressive strength, splitting tensile strength, friction coefficient and other aspects are better than the wear-resistant layer of iron dust mortar. The iron dust is easy to rust off, but the iron cast steel grit is not, the iron cast steel grit is the same Compared with diabase cast stone, the cost is low and the construction is simple. Its impact strength and brittleness value are about two times higher than diabase cast stone. Therefore, in the past 30 years, the wear-resistant layer of concrete or mortar is widely used in coal mine, electric power, chemical metallurgy and other industrial infrastructure projects.

  Emery and silicon carbide are synonyms that have been merged.

  Its hardness is between corundum and diamond, and its mechanical strength is higher than corundum. It can be used as abrasive and other industrial materials. Silicon carbide for industrial use was successfully developed in 1891. It is the earliest man-made abrasive. Although a small amount of silicon carbide exists in meteorite and crust, no ore source for mining has been found so far.

  Silicon carbide is a semiconductor with high hardness and excellent thermal conductivity. It can resist oxidation at high temperature.

  1.As an abrasive, it can be used to make abrasive tools, such as grinding wheel, Whetstone, grinding head, sand tile, etc.

  2.As metallurgical deoxidizer and high temperature resistant material.

  Silicon carbide has four main application fields, namely: functional ceramics, advanced refractories, abrasives and metallurgical raw materials. At present, a large amount of raw SiC can be supplied, which can not be regarded as high-tech products. However, the application of nano SiC powder with high technology content can not form scale economy in a short time.

  3. High purity single crystal can be used to make semiconductor and silicon carbide fiber.

  Main application: 3-12 inch single crystal silicon, polycrystalline silicon, potassium arsenide, quartz crystal, etc. Solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry engineering processing materials.
