Metallurgy of steel: specifics of production in the XX century, problems and prediction of future development

摘要

Major stages of development of metallurgical production of steel in the XX century are described and geopolitical factors defining its progress are formulated. Determinant role of energy consumption of aggloblast production is shown in energy balance of the integrated works. Alternative processes of steel production are considered. A significant reduction in power consumption can be attained in combination several technologies. Melting of steel and generation of conventional heat and electric power using the technologies of plasma electrometallurgical complex are challenging. Ways of metallurgy progress in the XXI century are outlined.
