high quality fire clay brick for furnace

Introduction of the fire clay brick

High strength refractory clay brick series used for the electric furnace are made by adoption of fused magnesite, high purity magnesium sand and graphite as principal raw material, through high pressure molding and low temperature treatment. This product is mainly used for electric furnace lining, which enjoys advantages including high temperature resistance strength, corrosion and spalling resistance. According to the smelting conditions and the kind of smelting steel, different brands refractory brick are available.

Characters of the fire clay brick

1). high strength

2). anti corrosion

3). abrasion resistance

4). washout resistance

5). long service life
