NLMK Commissions Revamped Continuous Caster at Lipetsk
09/23/2011 - NLMK has successfully cast the first slabs on the newly revamped 2.5 million tonne/year continuous casting machine at the company’s main production site in Lipetsk.
NLMK has successfully cast the first slabs on the newly revamped 2.5 million tonne/year continuous casting machine (CCM-8) at the company’s main production site in Lipetsk.
NLMK’s objectives for the CCM-8 reconstruction project included increasing output, expanding the product mix, and ensuring a consistently high quality of continuously cast slabs for further conversion into flats.
The continuous caster was fully revamped as part of the upgrade project, including replacement of ladle turrets and the installation of closed water cooling systems. CCM-8 is the first continuous caster in Russia to use a dynamic secondary cooling model to improve surface quality and internal structure of the semis. The facility also is fully equipped with an advanced automation and instrumentation system.
Following the CCM-8 revamp, NLMK has become the first Russian steelmaker to produce slabs with thicknesses of up to 355 mm for further conversion into thick plate, which are in high demand from mechanical engineering and power industries. Currently, continuous casting machines in Russia are only capable of producing slabs with a maximum thickness of 300 mm. NLMK will use the thicker slabs to produce thick plate at its DanSteel and Clabecq subsidiaries in Europe.
CCM-8 is the 5th production facility for continuous slab casting commissioned at the Lipetsk site following a revamp. CCM-3 is currently undergoing reconstruction at BOF Shop No.1. Following its commissioning, planned for Q4 2011, it will be able to produce up to 1 million tonnes/year of high-quality slabs.

The RUR4.7 billion CCM-8 upgrade is part of the second stage of NLMK’s Technical Upgrade Program, which, alongside other activities, is aimed at increasing annual steel output from 9 to 12.4 million tonnes at NLMK’s Lipetsk site. The company recently announced commencement of hot testing at its new Blast Furnace No. 7; in late September hot testing is scheduled to begin at BOF-6.
