Features Of Silica Brick:
Lower impurity content
Excellent resistance in slag abrasion
No shrink in burn repeatedly
Super higher cold crush strength character
Good performance in high temp refractoriness under load
Higher temperate resistant with good refractoriness
Application:
1. Specification:Standard&special shape;
2. Well resist acid slag erosion;
3. Refractoriness under load is close to refractoriness ;
4. Nondeformable under high temperature using
