Abstract
A forced cooling, metallic, refractory coated, high strength, modular, extreme heat withstanding, long life lining element for partial or total lining of metallurgical furnaces above the hot metal and slag levels, in particular melting Electric Arc and Plasma Arc Furnaces, with automatic coolant flow control, is disclosed. In accordance with the invention the forced cooling lining element consists of at least three (3) seamless, heavy wall boiler type pipes, arranged in generally parallel, eccentrically spaced non-contacting relation, with circular spacers, neighboring pipes being interconnected by welded mitres and elbows to create series or series-parallel serpentine and zig-zag structural pattern. The hot face of the pipes is provided with protective refractory anchoring system consisting of multitude coaxially and diagonally to the pipes arranged intermittent protuberances. Positive retention of the protective refractory-slag layer is controlled by means of heat extracting liquid coolant, flowing at high velocities and high pressure through the pipes structural pattern. The discharge flow of the liquid coolant such as water is controlled by an automatic flow control device which is an integral and constituent component of the element.
