Fireclay bricks are alumina silicate bricks with the refractoriness of SK 32-34 and contain 35- 45% alumina.The bricks are made from various raw materials of fire clay, calcined chamotte,mullite etc.they are highly resistant to abrasion,spalling and corrosion.Because the bricks have low porosity,high strength, good resistance to thermal spalling and to abrasion and to creep, Shengjie fireclay brick are applied for the linings of Coke Ovens,Glass furnace,Cement Kilns,Lime Kilns, various Incinerators, Reheating Furnaces etc.
Advantage:
Good performance in high temp refractoriness under load
Lower thermal line expansion in high temp
Good thermal shock resistance performance
Excellent resistance in slag abrasion
Good cold crush strength
Large stocks to meet prompt delivery
Strict Quality Control. Meet clients' quality requirement.
