The upgraded solution will further improve the OpEx of a competitive EAF.
Danieli will supply Magnitogorsk Iron & Steel Works -MMK with a new Q-MELT technological package for the existing, 180-ton EAF#2 at Magnitogorsk, Chelyabinsk region, Russia. The Danieli Q-MELT package will allow a further decrease in OpEx for an already performing EAF, which is being charged with up to 40% of hot metal. The order also includes an oxygen injector and a set of post-combustors for optimized chemical energy utilization.
The expected savings for the MMK EAF will be more than 2.5 USD per ton of liquid steel guaranteed, for a payback of 8 months only. The package will be installed during a planned EAF maintenance shutdown in Summer 2020. The Danieli Q-MELT EAF package consists of a Danieli Q-REG electrode regulator, Lindarc laser off-gas analysis tool and Danieli Melt Model heat optimization package.
After the first industrial installation in 2016, Danieli Q-MELT has upgraded more than 15 EAFs in USA, Europe, Russia, China, Far East, Africa and Middle East. Based on regional electricity costs, electrodes and carbon costs, Q-MELT installations recorded production savings up to 4 USD/ton.
