Hard 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,Jucos fireclay brick are applied for the
linings of Coke Ovens,Glass furnace,Cement Rotary Kilns,Lime Kilns,Various Incinerators,Reheating
Furnaces etc..
Features Of Fireclay Brick
Good performance in high temp refractoriness under load
Lower thermal line expansion in high temp
Lower impurity content
Good thermal shock resistance performance
Excellent resistance in slag abrasion
Good cold crush strength
