MMK Commissions Heavy-Plate Mill
August 7, 2009
Russia’s Magnitogorsk Iron & Steel Works (MMK) commissioned a heavy-plate mill designed and built by SMS Siemag. The core elements of the equipment are the mill housings, which weigh over 500 tons and make the roll stand – with a rolling force of 120 MN – one of the world’s most powerful heavy-plate mills. Designed for an annual capacity of 1.5 million tons, the mill will produce plates up to 4,800 mm (189 inches) wide. Production will focus on pipe grades as starting material for large-diameter pipes for use in the gas and oil sector. The order covered the complete process line for plate production with two walking-beam furnaces, the mill stand, plate cooling system, hot leveler, cooling and inspection bed, shear line, finishing area with cold leveler and heat-treatment facilities.
