Zirconium Corundum Castable

Zirconium corundum castables are constructed of refractory materials with an Al2O3 content of more than 90%, corundum as the primary crystal phase, mixed with the proper amount of coagulant, dispersion, and stainless steel fiber, and compounded in accordance with a precise formula. Refractory substance that is unformed

Steel fiber castable with good thermal stability and strong wear resistance can be created by adding a certain amount of steel fiber and additives to the castable. Zirconium corundum castables can then be used for heating furnace hearth, tapping troughs, the mouth of cement rotary kilns, and other parts.
Castables in corundum Fused corundum serves as the primary raw material for corundum refractory castables, which are then combined with various superfines and additives. The primary characteristics are high strength, great corrosion resistance, good volume stability, and resistance to reducing gases like H2 and CO.

Product Advantages:
1. Excellent high temperature performance: Zirconium corundum castable has excellent high temperature performance and can withstand erosion and thermal shock at high temperatures.
2. Good chemical stability: It has good chemical stability and will not be corroded by chemicals such as acids, alkalis, and salts.
3. High hardness: Zirconia corundum castable has high hardness and can be used to make high-strength, high-wear-resistant casting parts, such as nozzles, turbine blades, etc.
4. Strong impact resistance: It has good impact resistance and is not prone to cracking and other damage.
5. Good wear resistance: Zirconia corundum castable has high hardness and good wear resistance, and can be used to make wear-resistant cast parts.

Disadvantages of zirconium corundum castable:

1. Expensive: The raw material price of zirconia corundum castable is relatively high, and the processing technology is also more complicated, so it is more expensive.
2. Susceptible to thermal shock: Although zirconia corundum castable can withstand high-temperature thermal shock, it is prone to thermal shock under rapid temperature changes.

Zirconium corundum castables are mainly used for the lining of carbon black reaction furnaces and coal-water slurry gasification furnaces, and the operating temperature is generally above 1700 degrees.

It mainly used in furnaces in the glass industry, and have strong resistance to glass erosion.

Brown fused alumina castables have good wear resistance, and are generally used for coal injection pipes in power plants, boiler linings, and steel rolling heating furnace slide rails.

Composite corundum castable is a composite corundum castable made by adding specific materials according to different operating temperatures and environments. It is generally used in cement rotary kilns, non-ferrous metal melting furnaces, and steel industries.
