Product Description

Product Description

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.Applications

Blast Furnace

Various Incinerator

Reheating Furnace

Cement Rotary Kiln,Various Rotary Kiln

General Industrial Furnace etc.

Glass Furnace

Specifications
