Abstract
IN COKE-BASED STEELMAKING, COAL HAS AN IMPORTANT FUNCTION IN THE PRODUCTION OF METALLURGICAL COKE, WHICH WILL BE USED IN BLAST FURNACES FOR THE PRODUCTION OF HOT METAL. COKE IS PRODUCED FROM BLENDS OF COALS WITH DIFFERENT PROPERTIES, FORMULATED TO ATTEND THE OPERATIONAL REQUIREMENTS OF THE COKING PROCESS AND TO ENSURE THE QUALITY OF THE HOT METAL, WHICH WILL BE PRODUCED IN THE BLAST FURNACES. IN ADDITION, THIS MIXTURE SHOULD HAVE THE LOWEST POSSIBLE COST, SINCE MOST OF THE METALLURGICAL COAL USED IN BRAZIL IS IMPORTED THUS REPRESENTING A GREAT PART OF THE STEEL COST. THE GREAT CHALLENGE OF THE SECTOR IS TO OBTAIN MIXTURES OF COALS THAT ATTEND THE COKING PLANT AND PRODUCE COKE WITH HIGH QUALITY AND LOW COST. THEREFORE, IT IS NECESSARY TO OPTIMIZE SEVERAL PROCESSES, FROM THE PURCHASE AND TRANSPORTATION OF THE COAL TO ITS STORAGE, FORMATION OF THE BLENDS AND SUPPLY OF THE COKING PLANT. THE AIM OF THIS WORK IS TO OPTIMIZE AND PLAN THE COAL MIXTURE FOR THE COKING PLANT WITH THE USE OF RAW MATERIALS OF LOWER ADDED VALUE IN THE MIX THAT ALLOW THE PRODUCTION OF COKE WITH LOWER COST AND WITH THE QUALITY REQUIRED IN THE STEELMAKING PROCESS.
