Abstract: A method for inspecting a strip in a reversible rolling plant comprising at least one cage arranged between two winding/unwinding devices each having a mandrel. The rolling is performed in several passes until the requested thickness is obtained over the whole length of a useful part ranging between two service lengths maintained wound on each of the mandrels.According to the invention, at the end of the last pass between a winder/unwinder placed upstream of the cage in the rolling direction and acting as an uncoiler, and a downstream winder/unwinder acting as a coiler, the upstream service length is unwound completely from the uncoiler, then subjected to a roll pass; the strip is then cut in the vicinity of the end of its useful part to release, at its rear end in the direction of the last pass, an inspection length whereof at least one part corresponds to said upstream service length rolled once.

Abstract: A scanning system for monitoring the thickness, profile or other data from a moving product which includes a frame for mounting scanning transducers. The product is carried on a conveyor or the like through the frame and the transducers are mounted for transverse scanning motion across the top and bottom surfaces of the product at right angles to its direction of travel. Reference wires are connected between the side members of the frame and maintained at a constant tension independent of ambient temperatures. Reference wires are located between the transducers and both the top and bottom surfaces of the product. The wires provide a constant reference to detect distortion of the frame due to thermal or other stress and to provide correction data which is used to compensate for frame irregularities.

Abstract: The invention relates to a method for suppressing the influence of roll eccentricities on the run-out thickness of a rolled stock, which runs through a rolling stand, roll eccentricities being identified by using a process model and taken into consideration in the determination of a correction signal for at least one final control element, preferably a final control element for the adjustment position, of the rolling stand, wherein the measured tensile force upstream of the rolling stand is fed to the process model to identify the roll eccentricities. According to the invention, variations in tensile force are fed back in a targeted manner to reduce the effects of periodic roll eccentricities on the rolled stock, whereas all other sources of variation are eliminated. A process model of the rolling nip and the rolls, preferably based on the observer principle, produces reliable data on the roll eccentricity.
