First coil on mill upgrade

THE first coil has been produced on a reverse cold mill (RCM) modernised by Primetals Technologies at the cold rolling plant of Chinese steel producer Magang (Group) Holding Co (Masteel). The mill at the Maanshan production site represents the first upgrade to a hyper universal crown (UC) mill. Hyper UC mills employ smaller diameter work rolls, so reducing rolling loads. This allows for the production of harder and thinner materials with improved product quality. In addition, the mill concept saves investment and maintenance costs. The upgrade enables Masteel to meet the growing demand for electrical steels, spurred by increasing requirements for use in vehicle electrification. Masteel’s iron and steel complex in China’s Anhui province has production lines for thin strip cold-rolling and thin strip hot-rolling, strip hot-galvanising, strip colour coating, wire and rod.

The upgraded RCM processes silicon steel grades with product thicknesses between 0.3mm and 0.65mm, in a 900mm to 1,280mm width range.
