Silica Brick for Coke Oven

Silica bricks for coke oven are special bricks with complex types and sizes that used for coke oven and other thermal equipment with complex structures as refractory lining.

Product Description

What's coke oven bricks

Silica Refractory Brick is short for silica brick, it belongs to acid refractory brick and is suitable for lining material of high temperature kiln with acid atmosphere or solution. It is a kind of quality refractory products with more than 94-96% SiO2 content. Silica Refractory Brick has excellent resistance to acid corrosion, excellent heat conductivity and high refractoriness.

Silica bricks for coke oven is made of natural quartz stone with high SiO2 content (94%). Silica brick is used for coke oven's basic parts such as regenerator, chute, carbonization chamber, combustion chamber, coking chamber, furnace bottom and top, etc. The brick quality is one of the main factor that affect the service period of coke oven. With the enlargement of coke oven, the temperature in the main burning area has been rising, which requires higher quality bricks for oven.

Refractory coke oven bricks are coke oven bricks with tridymite as the main crystalline phase, used for building coke ovens. Modern coke ovens are large-scale heating equipment made of thousands of refractory materials and 10,000 tons of refractory materials.
