Description
Summary:The purposes of the work are elaboration of theoretical statements and technology for steel's reduction melting that is based on the usage of solid carbon, because at present time it is lack of theoretical and experimental data to make correct decisions, consider new technical requirements and raw material condition. So there are many reserves to conduct deeper and accurate investigations. Research methodology is worked out and is used for sequential-phase interaction between solid carbon and metal oxides. Replacement of hot reduction gases by solid carbon allow to reduce of specific gas outlet for mass unit of metal till 6-8 times, reduce of large metallurgical divisions for charge mixture preparation, implement of high-technology of steel's reduction melting with capability for direct alloying. Technological scheme of production chain is proposed. The samples of alloyed steel by manganese and chromium are obtained.
