FIRE CLAY BRICKS

FIRE CLAY BRICKS

Fire Clay Bricks 

Fireclay bricks are alumina silicate bricks with the refractoriness of SK 32-34 and contain 35- 40% alumina. The bricks are made from various raw materials of fire clay, calcined chamotte, soft clay. We manufacture chamotte bricks using thorough quality control. Shapes and properties depend upon service conditions. Because the bricks have low porosity, high strength, good resistance to thermal spalling and to abrasion and to creep, they are applied for the linings of Various Incinerators, reheating Furnaces etc.
