Brown corundum Production process

Why use emery and glass beads for sandblasting of carbon steel and stainless steel?

Corundum is a general term for a large class of corundum materials. Brown corundum , white corundum, black corundum, zirconium corundum, etc. can all be called corundum. Corundum (also known as silicon carbide) can be divided into natural corundum and artificial corundum, and silicon carbide has black corundum. There are two types of silicon carbide and green silicon carbide. Among them, black silicon carbide is made of quartz sand, petroleum coke and good silica as the main raw materials through high-temperature resistance furnace smelting. Is there any difference between emery and brown corundum? Brown corundum is made of industrial

Industrial silicon carbide is a semiconductor whose electrical conductivity varies with the type and amount of impurities introduced into the crystal, and its resistivity is between 10Ω·cm.

White corundum is an artificial abrasive. White corundum is made by melting industrial alumina powder in a high-temperature arc of more than 2,000 degrees and then cooling. It is crushed and shaped, magnetically separated to remove iron, and screened into various particle sizes. Its texture is dense, hardness is high, and the particles form sharp corners. Suitable for ceramic ceramics, resin consolidation abrasives, grinding, polishing, sandblasting, precision casting (special corundum for precision casting), etc.

The most commonly used white corundum powder for the production of oilstone, fused alumina powder 800 mesh 1000 mesh 1200 mesh 1500 mesh 2000 mesh.

Products made of grinding tungsten steel should be used Boron carbide 150#、800 #

Glass powder is often used in the filling of coatings. On the one hand, it improves the wear resistance of coatings, and on the other hand, it increases the refractoriness and high temperature resistance strength of coatings.
