Reducing energy demand and environmental emissions in secondary steel processing by using modular dry mechanical vacuum pumping systems

摘要

Steel production remains an energy-intensive industry in a world where there is an ever-increasing emphasis on lowering energy costs,reducing greenhouse gas emissions,ensuring environmental compliance,and improving production rates.As the growth in demand for speciality steels continues its steady increase,and new market opportunities for ever higher steel performance appear,significant global attention is focused on secondary steel processing,and on the VD,VOD and RH processes.One new technology is able to address all of these issues and concerns together-the integrated ladle tank vacuum degassing station equipped with the new modular mechanical vacuum pumping systems.This paper will examine the economic and environmental benefits, operational characteristics,and recent results provided by such steel degassing installations.
