VIZ-Steel improves surface quality of grain-oriented steel
VIZ-Steel (member of NLMK Group) has started installing high-tech electrolytic degreasing systems at its decarburizing annealing facilities. The new equipment is designed for cleaning the strip after the second cold rolling prior to applying heat-insulation coating. The project implementation will increase the share of GO steel with improved surface quality by 8%.
Modern systems of electrolytic degreasing will replace brush-washing machines, which clean the metal surface mechanically, using an alkaline cleaning solution. The new-generation equipment is fitted with special electrodes to create a medium with intensive gas-bubbling. The use of this technology ensures a cleaner removal of contamination from the strip surface, which remains after the process of rolling.
By the end of the first half of the year, 100% of decarburizing annealing units will be equipped with the high-tech electrolytic degreasing sections. The company will allocate about 240 million rubles for the implementation of this project.
