Luxembourg-based Paul Wurth, part of the SMS group, has been charged with the task of overhauling Russian steelmaker MMK’s blast furnace number two.
According to Paul Wurth, “After fundamental renewal and modernisation, the blast furnace will appear as a structure without a lintel ring. Paul Wurth will help MMK define the profile of the modernised furnace by considering the raw materials base and process conditions of the customer.”
It said that detail engineering will be provided for the high-heat loaded bosh and belly areas, cooling elements and primary cooling system. The company will also supply horizontally arranged copper cooling plates, highly conductive graphite refractory bricks and ramming mass.
“A complete set of EIC equipment for the dedicated pump house with heat exchangers and the related cooling circuit will be part of the deliverables,” Paul Wurth said, adding that on-site supervision will be performed during pre-shutdown and shutdown periods until commissioning.
At the moment, MMK’s blast furnace number two is ‘a typical furnace’. It was developed by AO ‘Magnitogorskiy Gipromez’ with an inner volume of 1,380 cubic metres, two tapholes and a daily production of 3,800 tons of hot metal. It was equipped with a compact-type BLT, developed by Paul Wurth, in March 2010, and in total has six original Paul Wurth Bell Less Top charging systems operated by MMK’s ironmaking facilities.
