Resumo

INTEGRATED IRON AND STEELMAKING PRODUCTION REPRESENTS THE GLOBALLY PREDOMINANT TECHNOLOGY. GLOBAL REQUIREMENTS FOR CO2 REDUCTION WILL HAVE IMPACT ON NEEDED CHANGES IN IRON AND STEELMAKING PHILOSOPHY USING NEW TECHNOLOGIES WHICH GENERATE LESS CO2. BASED ON FORECAST, HYDROGEN APPLICATION IN PRIMARY STEELMAKING AND SCRAP MELTING PROCESS WILL HAVE HIGHER SHARES IN PART OF WORLD WHERE INTEGRATED IRON AND STEELMAKING PROCESS IS CONSIDERED AS TRADITIONAL. TRANSITION FROM TRADITIONAL AND WELL-ESTABLISHED PROCESS TO THE PROCESS BASED ON DRI / HBI PRODUCTION TOGETHER WITH SCRAP MELTING IN ELECTRIC ARC FURNACE MUST BE FOLLOWED BY CAPABILITY TO PRODUCE HIGH QUALITY GRADES FROM CONTENT OF RESIDUALS ELEMENTS POINT OF VIEW. REQUIRED TRANSITION FROM INTEGRATED TO ELECTRICAL STEELMAKING PHILOSOPHY COULD HAVE IMPACT ON EXISTING SECONDARY METALLURGY PROCESS AS WELL. THIS ARTICLE PRESENTS WAY HOW TO KEEP CAPABILITY TO PRODUCE HIGH QUALITY GRADES WITH LOW CONTENT OF RESIDUAL ELEMENTS USING DIFFERENT CHARGED MATERIAL AND USING DIFFERENT SECONDARY METALLURGY CONFIGURATION.
