Silicon Carbide Castable

1. High refractoriness: Silicon carbide has high refractoriness and can maintain stable performance for a long time in high temperature environments above 1600°C.

2. Oxidation resistance: Silicon carbide castables have good antioxidant properties at high temperatures and can resist the erosion of oxidizing media such as oxygen and water vapor.

3. Corrosion resistance: Silicon carbide has excellent acid and alkali resistance and can effectively resist erosion by corrosive substances such as slag and metal oxides.

4. Wear resistance: Silicon carbide has high hardness and excellent wear resistance, and can resist wear under harsh conditions such as high temperature, high pressure and flowing media.

5. Good thermal conductivity: Silicon carbide has high thermal conductivity, which is beneficial to the rapid transfer and uniform distribution of heat in the furnace, and improves the thermal efficiency of the furnace equipment.

6. Easy to construct: Silicon carbide castable has good fluidity and can be poured, sprayed or tamped easily, simplifying the construction process.

Silicon carbide castables mainly use silicon carbide as the main raw material, add water reducing agent and ultrafine powder, and use pure calcium aluminate cement as the binding agent, which can greatly reduce the number of skinning times and is suitable for preheater unloading of large and medium-sized dry cement kilns. Slopes, rising flues, decomposition furnace cones and other parts.
