Silica brick /Silica powder/ Silica hot repairing mix

Silica brick is the main refractory bricks widely used in glass melting furnace;
Silica brick for glass melting furnace is used in building checker chamber, chute, combustion chamber, coking chamber and furnace arch.
Quantity:
  • CSR/04
  • CHENSHI

Characteristic:

1. Good acid and erosion resistance, powerful anti high-temperature strength.

2. Soften melting temperature is 1680 °C.

3. Low thermal shock resistance.

4. Natural silica as raw material, plus regular mineralizer.

5. Ensure good bonding and structural strength of furnace.

6. Good heat resistance and long service life.

Application:

1. Silica brick is the main refractory bricks widely used in glass melting furnace;

2. Silica brick for glass melting furnace is used in building checker chamber, chute, combustion chamber, coking chamber and furnace arch.
