Sheet piling and like steel shapes are made in a caliber rolling mill having upper and lower rolls of suitable contour. One of the rolls is axially fixed and the other can be shifted axially in opposite directions so that shoulders of the rolls engage and these positions are stored along with a relationship of axial force and spring constants of the mill frame. The rolling then takes these stored values into consideration.

Axial-position adjustment for profiled rolling-mill rolls

A rolling roll train of the staggered-roll tandem type has a pair of upright stand walls with windows or openings for receiving a multiplicity of pairs of rolls which can be changed as a unit. The fact that unitary walls with traverses between the walls for stabilizing them and where those traverses are located between the roll pairs, enables the spacing between the roll pairs to be substantially reduced by comparison with free-standing individual mill stands for the roll pairs.

Rolling mill train with staggered mills, especially as a tandem rolling installation

A rolling train for structural shapes in which at least on one side of a train having a plurality of mill stands, e.g. universal mill stands, a detector is provided for the actual profile of the rolled product. The actual profile is compared with a setpoint profile and corrected setpoint values for the operating parameters of the individual stands are generated for a corrected subsequent rolling operation or even the same rolling operation, appropriately weighted for the contribution of the various stands to the rolling effect.

Method of operating a rolling train and a control system for a rolling train

A universal rolling mill stand with horizontal and vertical rolls, adjustably supported in two parallel roll posts is disclosed. The universal rolling mill stand enables a simple construction and operational process if the horizontal rolls are received, without the help of installation pieces in bearings disposed in the roll posts 3, operator side roll post with the bearings face away from the drive elements and can be moved away in rolling axis direction of the horizontal rolls, from the other roll post. Vertical rolls, supported in adapters, are slid into guide frames solidly connected with the roll posts.
