Abstract

THE METALLIC YIELD OF A STEEL PLANT IS ONE OF THE MOST IMPACTFUL THEMES ON PRODUCTIVITY. ENERGY CONSUMPTION, COSTS, AND ENVIRONMENTAL IMPACT DUE TO CO2 EMISSIONS, ARE THE MAIN CAUSES, WHICH REQUIRES THE REDUCTION OF THESE METAL LOSSES AND ENSURING MAXIMUM YIELD. THIS WORK IS BASED ON A NEW CONCEPT ALREADY IMPLEMENTED IN STEEL PLANTS, WHOSE PRINCIPLE IS THE MODIFICATION OF THE STEEL LADLE BOTTOM DESIGN. THE TECHNOLOGY IS HIGH YIELD DESIGN. THIS WORK AIMS TO PUBLISH THE KNOWLEDGE LEARNED IN THE USE OF A NEW CONCEPT OF BOTTOM DESIGN OF STEEL LADLE COMBINING WITH OF CARBON-FREE STEEL LADLE REFRACTORIES, THROUGH AN ELABORATE PROFILE, WHICH ALLOWED THE REDUCTION BY 57% (PHYSICAL MODEL) AND 93% (INDUSTRIAL TEST) THE METALLIC LOSSES IN THE STEEL LADLES (WHICH CORRESPONDS TO A 0.8 TO 1.5% GAIN IN METAL YIELD), DEMONSTRATING THAT THEIR USE CAN BE AN IMPORTANT ALLY NOT ONLY IN ENERGY SAVINGS, HIGH-COST REDUCTION BUT ALSO A MAJOR FACTOR AT POLLUTING EMISSIONS DECREASE
