Refractory Brick (SK36 for blast furnace)

Detailed Product Description

The picture shows refractory brick for blast furnace. The type is SK36.

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 has wide applications, mainly used in metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.
