Abstract

A pipe-rolling plant preferably for manufacturing hot-rolled seamless pipes from a blank of circular cross section comprising a heating device, a reducer for deformation of a blank along the diameter is formed as a helical rolling mill, a device for broaching the blank into a hollow sleeve, a device for rolling the sleeve into a rough pipe comprising a set of stands of continuous longitudinal rolling on a mobile retaining mandrel, a roll forging machine and a device for calibrating the rough size pipe in a pipe of finishing size, which is designed as a mill of continuous longitudinal mandrelless rolling. A device for rolling the sleeve into the rough pipe comprises a set of three stands, the middle of which is idle one. The roll forging machine is formed as two mills of spiral rolling on short mandrels, located in parallel. The device for calibration comprises the second calibration mill located in parallel to the first one and a rotary piercer for hot dressing the pipes located downstream.
