NLMK Develops Creative Solutions for Assembly of New Blast Furnace

07/23/2009 - NLMK develops creative assembly operations to facilitate the ongoing construction of its new Blast Furnace No. 7 in Lipetsk, which is to have a total volume of 4290 cubic meters.

NLMK (Novolipetsk Steel) reports that it has developed some unique assembly operations to facilitate the ongoing work to construct its new Blast Furnace No. 7 in Lipetsk, which is to have a total volume of 4290 cubic meters.  
 
NLMK is implementing the project in cooperation with Paul Wurth (Luxemburg) and UZTM (Yekaterinburg) as part of the second stage of the company’s Technical Upgrading Program. 
 
As part of the construction, five sections of the blast furnace shell were assembled into one module that weighs more than 210 tonnes, which was lifted and installed at a height of 33 meters. This operation, which the company says has not previously been performed elsewhere, was carried out with special hoisting machinery that helped to ensure reduced costs and compliance with construction deadlines. 
 
The company reports that 12,000 tonnes of steel structures, 1,400 tonnes of equipment, 50,000 cubic meters of concrete structures, 200,000 refractories, 16 km of pipelines, and 4 km of railway tracks have been installed at the industrial complex construction site to date.
 
NLMK’s Blast Furnace No. 7 is the first such industrial complex to be constructed in Russia in over 20 years.  With a capacity of 3.4 million tonnes/year, the new facility incorporates technical solutions providing for high efficiency, resource saving and highly automated hot metal production. State-of-the-art production and waste treatment techniques will help to ensure enhanced economic and environmental performance. 
 
Installation of the furnace shell, bell less top and gas cleaning system is to be completed by the end of the year, and NLMK plans to commission the facility in mid-2012. Total investment in the construction is estimated to reach RUR 24.8 billion.
