METHOD OF PRODUCTION OF LIQUID CARBONACEOUS IRON BASED METAL

摘要

This invention is about a method of production of liquid carbonaceous iron based metal including the preparation of iron-carbon materials - pellets or briquettes - from finely dispersed complements, inserting them unto a closed induction electric furnace, post-combsution of evolving gas by oxygen or air in the volume over the bath and the transmission of the heat of burning to the reaction zone by radiation of dome, while in the components for the preparation of iron-carbon materials are dosed calculating to get the metal containing not more than 3 % C and the grain size of these materials less than 5 sm. To realize the claimed method it is offered to use induction crucible electric furnaces of the industrial frequency with the new destination, as aggregates for producing the metal from primary raw materials not for only melting, as they exploited now. Simultaneously with the main production the method permits to realize the utilization of secondary raw materials on a large scale. It satisfies the ecology demands too.
