fire brick(SK37)

Detailed Product Description

The photo shows fire brick with Al2O3 65%. This type is used for blast furnace.

 

Double Egret is the specialized manufacturer and exporter of refracotry and insulation material in north of China. Our products mainly include refractory brick, refractory castable, insulating brick, ceramic fiber products. For refractory brick, the production capacity is 500tons per month, primarily export to USA, AUSTRALIA, ITALY, JAPAN etc.

Refractory brick is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, refractory brick is the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.
Refractory brick for blast furnace is mainly used in stack, bosh, bellly and bottom of blast furnace.
