NLMK Upgrades Transformer Steel Facilities
09/28/2010 - Production has commenced at a new facility producing electric insulation coating for transformer steel at NLMK's main site in Lipetsk. The launch of the 60,000 tonnes-per-annum line is another step toward manufacturing nanostructured high-permeability transformer steel in 2011.
Production has commenced at a new facility producing electric insulation coating for transformer steel at NLMK's main site in Lipetsk. The launch of the 60,000 tonnes-per-annum line is another step in manufacturing a new steel product type in Russia in 2011, called nanostructured high-permeability transformer steel (HPTS).
NLMK notes that the capacity of this new facility exceeds that of its existing electric insulation coating lines by 30%. The line’s technical parameters allow for the metal heating and cooling rates required for HPTS production.
Refurbishment of a normalization line for hot flats and the construction of a new reversing mill with unique process capabilities are nearing completion at the Lipetsk site. The commissioning of these facilities, scheduled for the end of 2010, will make it possible to produce HPTS at the main site in Lipetsk. The planned production capacity for this product will be around 60,000 tonnes per annum.
Designed for the electrical industry, HPTS has an especially low rate of magnetic loss and complies with the best available technologies (BAT) standards, according to NLMK. Its application in power transformers is expected to reduce specific losses of electric energy by 10 to 15%.
Investments into the construction of the electric insulation coating line for transformer steel totaled about RUR 1.5 billion (~USD 50 million).
NLMK Group is a global leader in electrical transformer steel production. Production capacities at the company’s main site in Lipetsk and in its Yekaterinburg-based subsidiary VIZ-Stal exceed 340,000 tonnes per annum.
