Abstract: A section straightening machine is operated by a method which involves passing the structural sections through the array of straightening tools. Section straightening forces are applied to adjustable shafts carrying the tools and adjusters at the service sides of the shaft applying forces acting counter to the section straightening forces.

Abstract: In a straightening machine for straightening sections like rolled beams, wherein tools (11) are arranged on a plurality of mutually parallel driven straightening shafts (8, 9; 21a, 21b, 22a, 22b) disposed above and below the alignment line in the transport direction of the product to be straightened, and of which preferably the upper straightening shafts (2a, 21b) are adjustable for setting the straightening gap, the straightening shafts (2a, 21a, b) are individually adjustable and each have on both sides an adjusting means engaging straightening shaft ends (6, 7; 23a, 23b) whereby in straightening operations at least the adjusting means on the service side (6; 23a) remote from the drive side I is provided with a force (FA) acting opposite to the straightening force (FR) relevant hereto.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
