  • Refractory Material - an overview | ScienceDirect Topics

    Refractory materials are used to line smelting furnaces. The most usual lining configuration in North America is one that consists of a thin layer of insulation castable protected from the liquid metal by a monolithic material with nonwetting additives. European practice is to use fired bocks and bricks.
