The cost of the large-scale project, which was carried out for six months, was RUB 5.4 billion, out of which RUB 2.35 billion were allocated for the cost of equipment, while the rest was allocated to the construction and assembly of the works and other costs.
Changes undertook in the reconstructed furnace
As a part of the reconstruction process, a technical refitting of the furnace was carried out, which involved the complete dismantlement and replacement of all the old parts of the furnace.
As reported by the company, there has also been a change in the configuration and the construction of the casting beds, as they are now two-tiered. As a result, in the intermediary space, it is now possible to fit transportation flumes for pig iron and slag and aspiration system air ducts, without taking up additional space at the site, which improves the architecture of the blast furnace, and also solves the problems relating to work and environmental conversation.
The aspiration system enables the immediate removal of dust-laden gases from their site of production, which as a result prevents the emission of pollutants into the working space of the unit and the atmosphere.
The key technological equipment for the processing of pig iron and slag has been replaced by modern hydraulic equipment. The removal of dust in the stock houses will be carried out with the help of the equipment from the company ‘Ekotex’. It is a system designed for the trapping of solid particles from the aspiration and technological gases, which are produced during the preparation of burden for the blast furnaces.
The reconstruction of blast furnace No.1 and the construction of the aspiration system will reduce dust emissions by 600 tonnes a year. As a part of this project, the reconstruction and further equipping of the premise adjoining the casting beds was also undertaken.
About MMK
MMK’s blast furnace no.1 was built in 1932 by the American company McKee. Towards the end of 1990, the company’s blast furnace was fully dismantled and reconstructed from scratch. After this renovation, its volume increased to 1,370 cubic metres and productivity reached 1.2 MnT per annum.
MMK is one of the world`s largest steel producers and a leading Russian metals company. The company`s operations in Russia include a large steel-producing complex encompassing the entire production chain, from the preparation of iron ore to downstream processing of rolled steel.
In 2017, the company produced 12.9 MnT of crude steel and 11.6 MnT of commercial steel products. MMK Group had sales of USD 7,546 million and EBITDA of USD 2,032 million during the year.
