Resumo
HIGHEST PRODUCTIVITY AND COST-OPTIMIZED PRODUCTION ARE THE KEY COMPONENTS FOR INTEGRATED BOF STEELMAKING TO BE COMPETITIVE AND PROFITABLE IN THE LONG RUN. FOR THIS REASON, STEELPLANTS, - ESPECIALLY IN THE AMERICAS AND IN EUROPE, FOCUS ON REVAMPS, UPGRADES AND MODERNIZATION TO ENSURE HIGHEST PRODUCTIVITY, AVAILABILITY WITH MINIMUM MAINTENANCE EFFORT. THIS PAPER IS PRESENTING AN OVERVIEW OF SOME OF THE CURRENT REVAMP PROJECTS, LATEST TECHNOLOGY FEATURES AND AN OUTLOOK TOWARD A GREENER BOF OPERATION FUTURE. EXAMPLES FOR SUCCESSFUL CONVERTER REVAMPS WILL BE SHOWN BASED ON THE ONGOING PROJECTS AT TERNIUM 340T BOF AND ARCELOR MITTAL MONLEVADE 135T BOF. LATEST TECHNOLOGY FEATURES FOR PROCESS IMPROVEMENTS WILL INCLUDE, THE VAICON LINK CONVERTER SUSPENSION SYSTEM, THE VAICON SUBLANCE 2.0 FOR HIGHEST ACCURACY, SHORTER PROCESS TIME AND THE VAICON SLAG STOPPER FOR CONTACTLESS AND FULLY AUTOMATIC SLAG RETENTION, AS WELL AS A NEW RELINING MACHINE WHICH MAKES BOF RELINING PROCESS MUCH FASTER AND SAFER. IN THE LAST CHAPTER, AN OUTLOOK WILL BE PROVIDED WHICH ROLE THE BOF CONVERTER WILL PLAY IN FUTURE GREEN STEEL MAKING PROCESS SUCH AS DIRECT REDUCTION AND SMELTER AND SOLUTION TO REDUCED CO2 EMISSION WITH INCREASED SCRAP RATE.
