Fused Silica Brick for Coke Oven FCO-99
Features
■ Excellent thermal shock resistance; nearly zero thermal expansion;
■ Applied for hot repair of coke oven walls and soles; it could also be adopted for modular repairs of aged coke oven which is seriously damaged;
■ No long-term drying oven required, no preheating required, quick repair and more efficient;
■ High hot bending strength and hot crushing strength, longer service life.
