Silicon carbide (SiC) is made from quartz sand and petroleum coke or coal tar, wood chips and other raw materials by smelting in high temperature electric resistance furnace . In the high technology non-oxide refractory raw materials , such as C, N, B ,ilicon carbide is the most widely used and one of the most economic material. It can be called corundum or refractory sand.
Rongsheng Refractory has professional sales and after-sale service team who provide customers all-around service about product application, construction installation and operation technology training etc.
Low cement refractory castable mainly includes three types: high alumina refractory castable, mulite refractory castable, corundum refractory castable.
Product Description Of Low Cement Castable
Low cement castable is the castable whose CaO content less than 3%, usually the refractory cement dosage is from 3-8%, but high grade cement is needed to ensure the strength of the castable. Comparing to common refractory castable, low cement castable has better performance in high temperature, and require less water, it makes the castable has lower porosity and higher density.
CHARACTERISTICS
1.small thermal expansion
2.high thermal conductivity
3.not easy to have thermal stress
4.good thermal shock resistance
5.corrosion resistance
6.extreme cold or heat
7.high temperature creep resistant ability
Applications for black silicon carbide
1. as an abrasive, it can be used as a grinding tool, such as grinding wheel,oilstone,grinding head, sand tile, etc.
2. As a metallurgical deoxidizer andexotic material.
3. High-purity single crystal, which can be used for manufacturing semiconductors and manufacturingsilicon carbide fiber.
4.It can be used as deoxidizer for steelmaking and modifier for cast iron structure, and as raw material for manufacturing silicon tetrachloride.
5.It can be used as high temperature indirect heating material.
