NKMZ in cooperation with Paton Electric Welding Institute have constructed
a fundamentally new equipment which realizes the process of production of new
generation rolls-double-layer rolls with the operating layer of high-speed
steel or high-chromium iron. The rolls are manufactured with the method of
electroslag facing the operating surface layer with hot metal. By estimation of specialists from the leading machine-building companies and iron and steel works, the use of compound rolls is one of the main trends in the field of iron and steel industry development since they have a substantially longer service life and provide manufacture of high-quality rolled products. |
