The speed control method for a continuous processing line involves a control device in a continuous processing line solving an optimization problem consisting of a model representing the change over time in the length of each processed material in the processing equipment and storage equipment, constraints on the length, speed and operating conditions of the processed material in the processing equipment, and an evaluation function comprising the speed of the processed material in the processing equipment and the storage amount of the processed material in the storage equipment at regular intervals or each time a predetermined event occurs, thereby calculating a command value for controlling the speed of the processed material included in the evaluation function and manipulating the speed of the processed material based on the calculated command value.

The present invention relates to a method for detecting the amount of curved travel of a metal strip that travels while overlapping multiple layers at a spaced interval, the method including the steps of: using a plurality of distance meters arranged in a width direction of the metal strip on at least one side in the width direction of the metal strip overlapping multiple layers, measuring a distance from the installation position of the distance meter with respect to a direction intersecting the width direction of the metal strip, and detecting the layer of the metal strip that has curved traveled and the amount of curved travel using the installation position of the distance meter and the measured value.

The invention relates to a device for straightening and / or stretching rolled stock in the form of one or more rolled metal strips and in particular slit strips having an input-side drive and an output-side drive for the rolled stock, wherein at least one of the drives is a linear drive, wherein the linear drive has an upper, endless drive part and a lower, endless drive part which are guided in parallel via a common driving section for driving the rolled stock, and wherein the upper and the lower drive part have a plurality of elastic contact elements, which are arranged one behind the other in the driving direction, for driving the rolled stock. In order to more effectively straighten and / or stretch the rolled stock and thus achieve a good microstructure formation which is improved as far as possible, the device comprises a control and / or regulation system which is used to set a speed of the output-side drive that is higher than the speed of the input-side drive, and the elastic contact elements allow the rolled stock to be stretched beyond the yield point thereof within the driving section. The invention also relates to a method for straightening and / or stretching the rolled stock using such a device.

The invention relates to a device for straightening metal strips (1) and metal slit strips (2), in particular slit strips, with at least 2 straightening rollers (8), in particular without straightening rollers, with at least one downstream linear drive 4, which is equipped with tensile stresses on the material to be straightened and with means for detecting the tensile stresses on the metal strip (1) or (2).To enable an improved method for flexibly straightening metal strips, the linear drive is characterized by means for detecting the tensile stress and degree of stretch of the metal strips (1) or (2), as well as by a control device for regulating the drive power and the metal strip speed upstream of the linear drive (3) and the outstream linear drive (4), in order to selectively vary the tensile stress applied to the metal strip (1) or to the metal strips (2), or to keep the tensile stress constant downstream of the straightening rollers or due to the stretching of the metal strip despite changing drive speeds, or selectively to regulate the degree of stretch. The invention also relates to a method for straightening the metal strip (1) or (2) with such a device. Pre-split coils can be used on the unwinding reel.
