Abstract: PROBLEM TO BE SOLVED: To maintain conformity to especially narrow dimensional tolerance in manufacturing of a profiled rolling material at a relatively low manufacturing cost, in an operation method for a rolling path. SOLUTION: By comparing a measured profile (54) of the rolling material in process with a target profile, then based on a deviation of a measured profile from the target profile, modified target values (Ki ) in relation with weight factors (Wi ) inherent to each stand are replaced with the target values (SW) for entire rolling stands or each stand (4, 6, 8).

Abstract: A housing-free roll support frame comprises modular box element (KE), workpiece guide and chock retaining and guiding element (KA) components. A housing-free roll support frame for holding roll pairs mounted in chocks, and for removably fitting in a housing which is open at one side and which accommodates the roll drive transmission and screw-down equipment, consists of a box element (KE) with entry and exit passages (DG), workpiece guides and, mounted on the box element (KE), retaining and guiding elements (KA) for the chock pairs (LES) of each of the two-high rolls (W).

Abstract: Drawing regulating process comprises adjusting a tension element (6) with an actual adjusting force (F) on the rolled material section (5) so that the section deviates from the tension element by an actual deviation (z), acquiring the actual adjusting force (F) and the actual deviation (z), and adjusting a pull (Z) prevailing between the front and rear roll stands (2, 3) in the material section so that the actual adjusting force is approximately the same as the theoretical adjusting force (F asterisk ) and the actual deviation (z) is approximately the same as the theoretical deviation (z asterisk ). Preferred Features: The tension element (6) is adjusted on the rolled material section using a hydraulic cylinder (7). The actual adjusting force (F) is maintained constantly the same as the theoretical adjusting force (F asterisk ) and only the actual deviation (z) is variable.

Abstract: Regulating pull between roll stands of roll trains comprises quantitatively acquiring a fluctuation amplitude and fluctuation frequency during rolling rods or wires from the fluctuations that the rod or wire produce between two subsequent roll stands, and determining a pull and/or the pressure prevailing in the rolling stock between the roll stands by comparing with identification points.

Abstract: Roll gaps (s3-s10) of the active roll stands (3-10) are adjusted via hydraulic cylinder units (12) which are controlled by roll gap regulators (13) by whose frame springs of the active roll stands are compensated into fractions. The fractions are separately adjusted for each roll stand. Mill train has active roll stands operating in pairs and being adjustable to roll gaps. The rolled material (11) can be rolled to a final height (h) and a vertical final width (b) by applying rolling forces (F3-F10). Roll gaps (s3-s10) of the active roll stands (3-10) are adjusted via hydraulic cylinder units (12) which are controlled by roll gap regulators (13) by whose frame springs of the active roll stands are compensated into fractions. The fractions are separately adjusted for each roll stand.

Abstract: Method for operating a rolling train for producing profiles which contains several roller systems (4, 6, 8) comprises measuring the bar thickness, flange height and flange thickness produced by each roller system. These are compared with desired values and the rollers adjusted as required. An Independent claim is included for a control system for the roller train.
