MMK picks Paul Wurth for erection of new blast furnace

Paul Wurth has signed a contract with PJSC Magnitogorsk Iron and Steel Works (MMK) for a new major investment project – the construction of the new blast furnace No. 11.

As part of MMK Group’s development strategy and its strive for continuous improvements in production and ambitious environmental goals, the Russian steelmaker awarded Paul Wurth with an EP contract for the construction of its new blast furnace No. 11 at its Magnitogorsk works, Chelyabinsk region.

Paul Wurth was contracted to provide engineering, technological equipment supply of the blast furnace proper and important sub-plants for the new BF11. The new blast furnace, with a hearth diameter of 13.5 m, will have a working volume of 3 845 cubic meters and a production capacity of 3.7 million tonnes of hot metal per year. Paul Wurth will also provide supervision services for the erection work and commissioning. 

The construction of this new blast furnace complex will allow MMK to decommission three operating, but outdated furnaces (BF4, BF7 & BF8) and will integrate the most advanced technologies in terms of environmental protection. Along with substantial productivity improvements, MMK will thus be able to reduce harmful emissions by 6 600 tonnes per year and cut CO2 emissions by 1 123 tonnes per year.

Paul Wurth’s scope includes in particular:

  • the stockhouse, including raw materials receiving stations and conveyor systems;
  • four top-fired hot blast stoves;
  • the blast furnace proper with 4 tapholes, including TMT-type blast furnace probes, all refractory lining, cooling system and cooling elements (copper & cast iron staves);
  • Paul Wurth Bell-Less Top© charging system;
  • the blast distribution with cardan-type tuyere stocks and the tuyere phenomena detection system;
  • the casthouse with TMT-type casthouse machines
  • a dry gas cleaning system;
  • a Top gas Recovery Turbine (TRT);
  • stockhouse and casthouse dedusting;
  • two INBA slag granulation plants, serving 2 tapholes each.

The project schedule foresees a construction duration of 3.5 years.
