Metinvest revamps MMKI Heat Station -1

22 June 2012

At the first heat station of MMKI, which is a part of Metinvest Group, large-scale construction of turboblower № 3 was accomplished and it was commissioned at the 21 of June. It will allow to increase the productivity of blast furnace №3 to 7% and to reduce the specific consumption of coke to 7 kg/t of hot metal. The cost of the project is 31 mln $.

Among the technological  equipment  of Heat Station -1 the turboblower  №3 will be the most  up-to-date.  The 19th MW  turbine and  compressor with the production capacity  4000 m3 /min, according to the calculations of the Works technicians are to improve successfully  the quality of the blast for the Blast Furnace Shop,  to increase the productivity and to ensure the stable work of the blast furnaces.

Taking into account that at present  8 air blowers are already working at the Heat Station -1, the technicians  found the way  to implement at the Works  proven, efficient, high-power computerized  turbine    compatible with  the already existing equipment.

“Commissioning of the new turboblower  is only the first stage of the  integrated programme of Works  technological revamp up to 2020. In the nearest future  it is planned  to  repair the 5th and the 6th  blowers at the Heat Station №1”-pointed out the  Head of the Works Vladimir Boyko. The start-up of the turboblower  -3н will provide the Blast Furnace Shop with more than 4000 m3 of  blast and will allow to  use more flexible system  of maintenance repairs. It will also provide the necessary conditions for the development of the Blast Furnace Shop.  Among them are  the capital repair  of the Blast Furnace  №2  and further reconstruction  of the Blast Furnace  Shop taking into account the repair works at the Blast Furnace №1.
