METHOD FOR PRODUCTION OF INTERMEDIATE PRODUCT FOR METALLURGY PROCESS Russian patent published in 1997 - IPC

Abstract RU 2075516 C1

FIELD: nonferrous metallurgy, particular, production of charge materials (intermediate product) for steel making. SUBSTANCE: method for production of intermediate product for metallurgy process includes formation of intermediate product from solid filler and liquid iron-carbon alloy. Intermediate product is formed by loading onto the surface of liquid iron- carbon alloy of solid filler preliminarily filled into mold, immersion of solid filler into liquid phase under the action of the force exceeding lift Archemedean force not less than by 5%. Solid filler is used in form of oxidizer with total quantity of oxygen required for oxidation of 5-95% of carbon and full oxidation of the other components possessing affinity to oxygen higher than that of carbon. EFFECT: higher efficiency. 2 cl, 1 tbl
