LMF Fume Extraction System at Corus-Teesside Cast Products

摘要

When looking for operational improvements that reduce costs in any area of steelmaking, it is rare to find a change that produces benefits with no drawbacks. The implementation of a new LMF roof design incorporating peripheral fume extraction not only addressed all the problems and inefficiencies suffered by Corus, but it has also yielded additional benefits. Improved efficiency of fume extraction has resulted in: Power savings. Extraction equipment savings. Environmental benefits. Redirection of a majority of the fumes has resulted in: Potential graphite savings. Quality benefits. Having a roof free of slag has resulted in: Downtime and repair savings. Safety benefits. Improved roof cooling has resulted in: Refractory consumption savings. Increased roof life. The roof of success for any capital expenditure in a steel plant is the purchase of another unit of the same design. Corus purchased and installed its second LMF roof with this new design approximately six months after installation of the first one.
