Abstract

AS THE BACKBONE OF THE LARGEST INDUSTRIAL ECONOMIES, THE STEEL INDUSTRY WILL CONTINUE TO IMPROVE ITS ENERGY EFFICIENCY WITH A VIEW TO MEETING THE NEW AMBITIOUS CO2 EMISSION REDUCTION TARGETS SET BY MANY GOVERNMENTS AROUND THE WORLD. HIGH PRESSURE DESCALING IS A MAJOR CONSUMER OF ELECTRICAL ENERGY IN THE HOT ROLLING PROCESS; IN ADDITION, THE TREND TOWARDS EVER-INCREASING WATER PRESSURES IN DESCALING HAS LED TO INCREASED PUMP CAPACITIES AND A CORRESPONDING RISE IN ENERGY CONSUMPTION AND COSTS. LECHLER’S INNOVATIVE SCALEMASTER ECO+ NOZZLE CAN HELP TURNING AROUND THIS TREND AND REDUCE ENERGY CONSUMPTION IN HOT ROLLING CONSIDERABLY, LOWER CO2 EMISSIONS AND SAVE OPERATION COSTS. FURTHERMORE, CERTAIN NEW CONCEPTUAL IDEAS OF NOZZLE ARRANGEMENTS UTILIZING THE OPTIMIZED DESCALING NOZZLES ENABLE THE SURFACE QUALITY OF ROLLED MATERIAL TO BE CONSIDERABLY IMPROVED COMPARED TO EXISTING INSTALLATIONS. THE PAPER WILL ELABORATE ON RESULTS OF LABORATORY AND FIELD TESTS, PRODUCT DETAILS AND APPLICATION ENGINEERING ASPECTS FOR BOTH THE DESIGNER OF SYSTEMS AND THE USER OF DESCALING SYSTEMS
