The reconstruction of Magnitogorsk Iron and Steel Works’ (MMK) blast furnace No.1 has been completed in the run up to the Day of the Metallurgist. The history of the company dates back to the launch of this blast furnace in 1932. The new equipment will enable the company to significantly reduce its ecological pressure on the environment.
The cost of the large-scale project, which was carried out in under six months, was RUB 5.4 billion, 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. As 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 elements in the furnace. It was the first time in MMK’s practice that part of the furnace was built by the company ‘Danieli Corus’ with copper horizontal fridges.
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.
