Standard Size Good corrosion resistance Silicon Carbide Refractory Bricks
Introduction:
Silica brick is an acid refractory material, which has good resistance to acid slag erosion. The softening temperature of the load is as high as 1640 to 1700°C. The long-term use volume at a high temperature is relatively stable.
Silicon carbide brick features:
1. Good thermal conductivity,
2. Good high temperature strength,
3. Wear resistant and erosion resistant,
4. Good thermal shock resistance,
5. Good corrosion resistance,
6. Good oxidation resistance.
Silicon carbide stopper brick application:
1. It is mainly used in precision casting.
2. used at the bottom of the stopper rod
3. It’s tightly matched with nozzle brick.
