Abstract
A rolling mill plant has a planetary skew rolling mill and a reducing or sizing rolling line disposed at a short distance therebeyond for the purpose of manufacturing tubes. In order to avoid axial stressing of the work material between the planetary skew rolling mill and the reducing or sizing rolling line when the work material is simultaneously located in both of them, a tension and compression measuring device is disposed in the region of the reducing or sizing rolling line for the purpose of corresponding regulation of the latter's drive motor. A torque measuring device is disposed between the mounting of the mandrel rod of the planetary skew rolling mill in order to be able to detect torque stresses in the work material which are then eliminated in dependence upon the measured values of the torque measuring device by corresponding regulation of the rotational speed of the rolls and of the rotor of the planetary skew rolling mill.
