Paul Wurth to Implement Blast Furnace 11 Construction at MMK
Russian steel giant Magnitogorsk Iron and Steel Works and SMS Group’s subsidiary Paul Wurth have signed a contract for the implementation of the investment project Construction of a new blast furnace No 11. The working volume of the new blast furnace will be 3,800 cubic meters, the capacity 3.7 million tons of pig iron per year. The new blast furnace will be built using the world's best technology. The complex of the new furnace will use
Conveyor supply of raw materials to the top of the top to the loading device
A closed cooling system with copper refrigerators, which will ensure the preservation of the working profile of the furnace in the zone with the most aggressive effects of physical and chemical processes
Tuyere devices of the siphon type, allowing to raise the temperature of the hot blast to 1300 degree Celsius, which will reduce the specific consumption of coke
Shaftless air heaters using a combustion air and gas heating system, which will significantly reduce emissions of NOX , CO2 and other harmful substances
Dry gas cleaning system, providing dust content at the outlet of no more than 5 milligrams per cubic metre
Gas utilization compressor less turbine, which will allow to generate an additional 22 MW of electricity
In addition, the new furnace will be equipped with aspiration systems for foundry yards, bunker rooms and blast-furnace slag granulation. Also, the furnace will be equipped with a closed circulation water supply cycle.
The use of advanced technology, high equipment complex new blast furnace environmental objects and disabling of obsolete furnaces allow only CMI in this project to reduce emissions of harmful substances into the atmosphere at 6.6 tonnes per year, while CO2 emissions will be 1,123 thousand tonnes per year.
The construction of the blast furnace No 11 complex will be a breakthrough for the blast furnace production of Magnitka, will allow the decommissioning of three currently operating furnaces, and will significantly improve the economic and environmental performance of production. The project is designed for 3.5 years. The volume of investments of PJSC MMK will amount to about USD 690 million. The IRR of the project is about 30%.
