Abstract

See full text

An unfired, refractory molded body (1), includes a binding agent matrix (2) containing at least one set, permanent binding material and aggregate grains (3) with and/or of biogenic silicic acid, preferably with and/or of rice husk ash, which grains are incorporated into the binding agent matrix (2), for thermal isolation of a molten metal, especially of molten steel, and/or of a metal ingot solidifying from the molten metal, and also the use of the molded body (1) for thermal isolation of a refractory lining, in particular in a multiple-layer brick wall or in a heat-treatment furnace, or as a corrosion barrier, e.g. against alkali attack, or as a fire protection lining or as filter material for hot gases.
