Product Details
Silica brick is made of silicon as raw material with high temp firing ,which silicon oxide is above93%, used in hot blast furnace,coke oven,glass kiln,these brick have good volume stability at high temperature, high refractoriness under the load,small rate of shrinkage in working condition.
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
Applications Of Silica Brick
Hot-blast furnace
Coke oven
Glass kiln
Specifications Of Silica Brick
Silica contents range from 94% to 96%
Widely used throughout Hot-blast furnace .coke oven.Glass kiln
