Detailed Product Description
The picture shows refractory brick SK34, Al2O3 42%. This brick is mainly used for hot-blast stove.
DOUBLE EGRET is the specialized manufacturer and exporter of insulation and refractory material in north of China with more than 10 years' history. The products include refractory brick, refractory casable, insulating brick, ceramic fiber etc. For refractory brick Double Egret primarily exports to UK, 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.
Fireclay refractory brick for hot-blast furnace is mainly used as lining brick in the low and medium tempertature area and checker brick of hot-blast stove. High Alumina refractory brick for hot-blast stove is mainly used in the high temperature zone, such as arch roof, burning chamber bridge wall, checker brick etc.
