Fireclay Refractory brick for blast furnace is used in the part of throat, stack, hearth, bottom for a small blast furnace and the stack for a big blast furnace. NRCL manufactuer a compelete ranges fireclay bricks for blast furnaces.

Firebricks are composed from a blend of usually two or more clays. The use of flint and kaolin clays imparts refractoriness, calcined clays (chamottes) control the drying and firing shrinkages and plastic clays facilitate forming and bonding strength.
