Abstract (en)
[origin: EP0156922A1] An inclined rolling mill includes pressure rolls with an inlet side interfacial angle and an outlet-side interfacial angle which are disposed with an inclination such as to provide a predetermined angle of lead. The rolling mill is provided with a pair of drivable drive roller shoes with an inlet-side interfacial angle and an outlet-side interfacial angle which are disposed at a position adjacent to the pressure rolls with an inclination such as to provide a predetermined angle of lead. Thus, it is possible to stably support a blank pipe being rolled with a compact structure and to effect smooth rolling.
