Dolomite-dunite mixture as a patching material for steel melting furnaces

Abstract

Production tests have been made of a dolomite-dunite mixture in the 250–650 ton open hearths of the Makeevka, Krivoi Rog, and Kommunarsk Metallurgical Combines in patching the rear walls, banks, and front bulkheads. The tests established no differences in use of the mixture in comparison with fired dolomite and no differences were established in the process.
