Silicon carbide castables are mainly 75~98% of silicon + carbide as the main raw material, adding high-efficiency water reducer and ultrafine powder, with pure calcium aluminate cement as the binder, thus made into amorphous refractory material. which is the first choice for non-ferrous metal melting furnaces, blast furnace ironmaking grooves, cupolas, and other high-temperature record materials. The performance indicators of silicon carbide castables are similar to silicon carbide bricks and can be used for the on-site casting of kilns.

The performance indicators of silicon carbide castables are similar to silicon carbide bricks and can be used for the on-site casting of kilns. During construction, it can also be made into refractory prefabricated parts and prefabricated blocks, which can be used directly after drying and moisture.
Silicon carbide castables can greatly reduce the number of skidding with the advantages of fast heat conduction, compact volume, good oxidation resistance, good wear resistance, strong resistance to erosion, erosion, permeability, and so on. The service temperature of silicon carbide castables is generally 1500-1700℃.

The biggest advantage of silicon carbide refractory castables is that it has high thermal conductivity, low thermal expansion, and does not react with slag. It has been used as a slag reaction and high-temperature spalling kiln parts very early.
1. Silicon carbide castables have high thermal conductivity.
2. Silicon carbide castables have good resistance to flaking.
3. Silicon carbide castables have resistant to erosion and erosion.
4. Silicon carbide castables have a small thermal expansion coefficient.
5. Silicon carbide castables have high-temperature environment wear resistance.
It is widely used in kilns, furnaces, and thermal equipment of metallurgy, petroleum industry, chemical industry, building material, machinery, etc.
Cr2O3 in chrome corundum castables has very low solubility in molten slag, as Cr2O3 can enhance the viscosity of molten slag, then the dissolution erosion rate of chrome corundum castables is reduced. So chrome corundum castables are important refractory materials used for oxidizing atmosphere-melting furnace working lining.
The more SIC content, the better the anti-skinning function of the refractory material, and the better the alkali resistance.
Silicon carbide castables have high thermal conductivity and a small thermal expansion coefficient. SIC refractory castables are difficult to penetrate with molten steel and slag. High-temperature oxidation is a protective oxidation, and oxygen resistance is significantly better than carbon materials.
Based on the SIC body, silicon carbide is wear-resistant and silicon carbide has high hardness.
