Problems solved by technology
The low-roughness strip steel and flat rolls are particularly prone to relative slippage. When the strip steel and flat rolls slide relative to each other, it will not only cause scratches on the strip surface, but also cause fluctuations in rolling parameters. , when the relative sliding between the phase strip steel and the plate-shaped roller is serious, it will cause the unit to break the belt accident and affect the stable operation of the production line

The invention relates to the technical field of strip steel treatment processes, in particular to a strip steel and strip shape roller slip judgment method and device based on a double-rack temper mill. The method comprises the steps that the first strip steel elongation of a first rack is obtained based on the current speed of an inlet tension roller and the current speed of a plate-shaped roller; based on the current speed of the outlet tension roller and the current speed of the plate-shaped roller, the second strip steel elongation of a second rack is obtained; and according to the first strip steel ductility and the second strip steel ductility, whether slipping occurs between the strip steel and the strip shape roller or not is judged. According to the embodiment of the invention, on the basis of the strip steel elongation rates of the first rack and the second rack, whether the strip steel and the strip-shaped roller slip or not is accurately discriminated, so that a guarantee is provided for quickly processing faults and ensuring stable operation of a unit; the technical problem that in the prior art, whether slipping occurs between the strip steel and the strip-shaped roller of the double-rack temper mill cannot be accurately detected is solved.
Description
technical field [0001] The invention relates to the technical field of strip steel processing technology, in particular to a method and device for determining the slippage of strip steel and plate-shaped rollers based on a double-frame skin pass mill. Background technique [0002] The double-rack leveling machine undertakes the production and processing tasks of thin-gauge bright plates and other plates with high requirements on the flatness of the steel surface. The strip with low roughness and the flat rolls are particularly prone to relative sliding. When the strip and the flat rolls slide relative to each other, it will not only cause scratches on the surface of the strip, but also cause fluctuations in rolling parameters. , When the relative sliding between the phase strip and the flat roll is serious, it will cause the unit to have a broken belt accident, which will affect the stable operation of the production line. [0003] Therefore, how to accurately detect whethe...
