refractory materials used in furnaces service life

  • Refractory Material for Furnaces in Smelting Industry

    Furnaces are built of refractory materials —heat resisting substances often in the form of bricks of standard shapes made from selected clays and other rocks blended, moulded to shape and fired at high temperature. These bricks are assembled within a steel or cast iron framework or shell to form the furnace, flues and other accessory parts which reach high temperatures.
