Stainless steel special cutting piece

Stainless steel special cutting slice is a kind of cutting slice, as the name implies, it is used to cut stainless steel cutting slice. There are many materials for this kind of cutting piece. Here is a brief introduction for you.

1. White corundum: It is made from industrial alumina powder, which is melted in arc at high temperature above 2000 degrees, and then cooled. It is crushed and shaped, removed iron by magnetic separation, and sifted into many kinds of granularity. Its texture is compact and hardness is high. It is suitable for manufacturing ceramics, resin-bonded abrasives, grinding, polishing, sand blasting, precision casting (corundum for precision casting), etc. It can also be used for manufacturing. Making high-grade refractories.

2. Brown corundum: Made of bauxite and coke (anthracite) as the main raw materials and smelted at high temperature in the electric arc furnace, the abrasive tools made of it are suitable for grinding metals with high tensile resistance, such as various general purpose steels, malleable cast iron, hard bronze, etc., and also for manufacturing high-grade refractories. It has the characteristics of high purity, good crystallization, strong fluidity, low linear expansion coefficient and corrosion resistance.

3. Silicon carbide: It is made from quartz sand, petroleum coke (or coal coke) and sawdust by high temperature smelting in resistance furnace. Among the non-oxide high-tech refractory materials such as C, N and B, silicon carbide is the most widely used and economical one. It can be called gold-steel sand or refractory sand.
