ABSTRACT:
A runner for hot metal as from a blast furnace is formed of a series of interconnected modular units which are prefabricated from consumable combustible, and/or disintegrable materials of desired densities resulting in a calculated exposure life determined by the amount, the time and the temperature of the molten metal handled by the runners. The modular runners are formed of a mixture including clay, wood chips, paper pulp and/or any combustible material, which when mixed or blended with any refractory produces a consumable, disintegrating combustible mixture that has a disintegration or combustion rate dictated by the density of the compaction of the material in the finished product.
