refractory material weight function

  • 11.5 Refractory Manufacturing

    Refractory materials used as furnace linings require a certain minimum strength and creep resistance to ensure that they do not rupture or creep under their own weight. A high thermal resistance or refractoriness under load are further prerequisites for the required dimensional stability, i.e. creep and subsequent sintering of the refractory materials are not permissible.

  • Adaptation of Odolewu Clay for Use as Refractory Material

    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.
