ABSTRACT:
A runner for hot metal as from a blast furnace is formed of a series of interconnected modular units, each of which is prefabricated from materials usable as conventional fire bricks, the body of said runner being a unitary mass formed of successive layers of said material, each of said layers being coalesced under the influence of physical force not under thermal influence to a different density with no reinforcement thereby providing a known life and a visible indication of the degree to which the runner is worn away by the passage of hot metal therethrough.
