Housingless mill stands
MWE Mill stands are housingless mill stands. This implies that, during the forming process, the separating force is not absorbed by a housing. On the modern mill stands of an extremely rigid design, the separating force is taken up by tie rods between the chocks.
The rolls are supported in antifriction bearings. Tapered roller bearings are used for designs without provision for axial positioning of the rolls, whereas mill stands featuring axial roll positioning come with cylindrical-roller radial bearings in combination with grooved thrust ball bearings.
The rugged construction we have furnished traditionally is complemented by a guide frame which, while accommodating the rest bars and the screwdown gear drives, retains the chocks in place even at the highest loads. Hydraulic clamping mechanisms are provided to mount the guide frame firmly to the roll unit during the rolling process.
