Abstract

ACINDAR A STEEL COMPANY WITH TWO 110 T ELECTRIC ARC FURNACE (EAF) FOCUSED ON TO INCREASE EFFICIENCY AND COST REDUCTION OF THE STEELMAKING PROCESS, PLANNED TO REVAMP THE CHEMICAL ENERGY PACKAGE CHANGING THE EQUIPMENT OF OXYGEN AND CARBON INJECTION ON THE TWO EAFS WITH THE GOAL OF DECREASE THE CONSUMPTION OF INJECTED CARBON, OXYGEN AND BETTER SLAG FOAMING. THE TWO EAF USE TO CHARGE SCRAP AND DRI CONTINUOUSLY FEEDING WITH THREE PORTS OF BURNER/OXYGEN AND CARBON INJECTION. THIS PROJECT CONSISTED IN REPLACING THE EXISTING THREE PORTS OF BURNER/OXYGEN AND CARBON INJECTION FOR A NEW EAF CHEMICAL PACKAGE, COMPOSED BY COPPER BLOCKS, BURNERS AND INJECTORS OF OXYGEN AND CARBON. SEARCHING FOR THE BEST TECHNOLOGY CURRENTLY AVAILABLE IN THE MARKET, THEY CHOSE THE CHEMICAL PACKAGE DEVELOPED BY LUMAR TO EAF, COMPOSED BY PROTECT BLOCK, FLEXOX AND POWER CARBON (TO THE NEEDY CARBURIZATION POINTS). IN THIS PAPER WILL BE PRESENTING THE CHEMICAL PACKAGE EQUIPMENTS IMPLEMENTED IN THESE EAF’S REVAMP, AS WELL THE INSTALLATION PROJECT, BESIDES THE OPERATIONAL RESULTS OBTAINED DURING STARTUP. THE MAIN RESULTS WERE THE REDUCTION OF THE CONSUMPTION OF THE CARBON, OXYGEN, IMPROVEMENT OF THE FORMATION OF FOAMING SLAG AND REDUCTION OF ENERGY CONSUMPTION OF THE FURNACES.
