Ring-rolling mills and lines for production of ring workpieces

In the VNIImetmash during long time, the scientific-research works were carrying out on development, investigation and improvement of the technological process of longitudinal and longitudinally-transversal rolling of ring metal products. The designs of ring-rolling mills of different modifications have been created for rolling the rings from carbon, alloy, corrosion resistant steels and titanium alloys with outer diameter 90-5000 mm and height 23-1800 mm. The control systems of rolling process on the longitudinal rolling mills and the lines for ring workpieces production are described.
