Today Magnitogorsk Iron and Steel Works has signed the contract for the supply of the equipment to be used in the construction of the secondary metallurgy plant for CCM No.6 of the basic oxygen furnace shop.
The commissioning of the Plate Mill Complex and Cold-rolling Complex in 2009-2010 will allow to broaden the range of steel grades produced by the BOF and will call for the increase in capacity of secondary metallurgy plant and ability to treat the steel using state-of-the-art technology.
The technology of making steel for producing premium quality automotive sheets and large diameter pipes imposes rigid requirements for steel quality. Almost all steel of the above-mentioned grades has to be vacuum-treated. The construction of the secondary metallurgy plant will ensure serial casting of steel by CCM No. 6 up to Х120 strength class to be used in producing premium quality automotive sheets for exterior automobile parts and broaden the range of steel grades and secondary metallurgy capacities of the BOF designed to desulfurize and perform deep decarburization of treated steel; increase the volume of steel vacuum-treated in the BOF.
The production of crude steel will amount to at least 2 million tons per year. The facilities will be fitted with the state-of-the-art equipment ensuring the processing of any steel grades produced in the BOF Shop including the steel grades used for production of automotive steel sheets, large diameter longitudinal welded pipes of enhanced hydrogen-sulfide resistance and corrosion resistant pipes of X80 and higher strength classes; special steel grades; shipbuilding and high pressure vessels steel grades; steel grades used in automotive industry (ultra low carbon steel, high strength steel, dual phase steel, multi-phase steel and TRIP steel).
The process equipment of the secondary metallurgy plant will include the following machinery: twin ladle-furnace, twin circulation-type vacuum degasser, slag removal stand for the casting ladle and homogenization unit for soft blowing the steel in the ladle.
The contract for the equipment supply has been awarded to SMS Mevac.
