Zhengzhou Kewei Silica Bricks For Coke Ovens

Silica Bricks For Coke Ovens

Refractory bricks for coke ovens are predominantly silica bricks, accounting for about 70% of the total refractory materials. They are currently known as the most suitable refractory bricks for carbonization chamber walls.

Product Details

Performance & Advantages:

  • High refractoriness under load (RUL: 1,620–1,660°C), approaching its melting point;

  • Excellent thermal conductivity;

  • Resistance to acidic corrosion;

  • Poor thermal shock resistance (prone to cracking below 600°C), minimal residual expansion.


Applications:

Silica bricks for coke ovens are mainly used in industries such as glass, metallurgy, cement, carbon, and steel.Deployed in core high-temperature zones including combustion chambers, carbonization chamber walls, and flue ducts.
