Steel-making process employing an auxiliary composition
Abstract
Abstract A COMPOSITION FOR CHARGING TO A METALLURGICAL FURNACE, SUCH AS AN OCYGEN STEEL FURNACE WHICH IS A HEAT- AND FLUXPRODUCING AGENT CONSISTING ESSENTIALLY OF A GRANULAR ADMIXTURE OF FROM 5% TO 95% CALCIUM CARBIDE AND FROM 95% TO 5% SILICON CARBIDE. BOTH COMPONENTS PROVIDE FUEL TO ENABLE THE USE OF HIGHER AMOUNTS OF SCRAP METAL; AND IN ONE EMBODIMENT THE SILICON CARBIDE AND CALCIUM CARBIDE ARE ADMIXED IN A RATIO TO GIVE AN EVENTUAL SLAG OF SUITABLE LIME-SILICA RATIO. THE ADMIXTURE OF SILICON CARBIDE AND CALCIUM CARBIDE IS ADVANTAGEOUSLY ADMIXED WITH A MINOR AMOUNT OF A HYDROCARBON BONDING AGENT WHICH IS AT LEAST SEMI-SOLID AT ORDINARY ROOM TEMPERATURES, SUCH AS TAR OR PITCH, AND FORMED INTO COMPACTS, E.G. PELLETS OR BRIQUETTES. POWDERED ALUMINUM METAL CAN ALSO BE INCORPORATED.
