Tenova received a contract for the supply of a decarburization and coating line (DCL) from VIZ-Stal (NLMK Group) for its plant in Ekaterinburg, Russia. The line will provide one of the important stages of grain-oriented (GO) electrical strip production. The contract includes the engineering, supply and supervision services of the heat-treatment furnace; mechanical and process equipment; and the related electrical, measuring and control systems. The DCL line is scheduled to start production by the end of 2021.
