Problems solved by technology

Because the existing deviation correction devices all adopt hydraulic actuators, the structure is complex, the maintenance cost is high, the failure rate is high, the deviation correction response is slow, and the deviation of the strip occurs from time to time, which affects the production efficiency and strip quality
In addition, the friction force between the strip and the correction roller fluctuates depending on the surface finish of the roller and the tension of the strip, which is prone to scratches on the surface of the strip

Embodiment 1

[0026] see Figure 5 , The invention is applied to the deviation correction of the pickling loop section of cold-rolled silicon steel sheets. Steel strip 1 passes through tension roller 12, spiral magnetic correction roller 13, 15, 17, then passes through turning roller 14 and 16, enters degreasing tank 18, washing tank 19, pickling tank 20, washing tank 21. Among them, the deviation correction rollers 13, 15, 17 correct the deviation of the strip steel 1 at the two ends of the loop, so that the strip steel 1 enters the degreasing tank and the pickling tank centeredly, thereby improving the deviation correction accuracy and improving the degreasing and pickling effects of the strip steel 1 surface. Among the figure: 22 is a hoist, and 23 is a looper tension trolley.

Embodiment 2

[0028] see Figure 6 , the present invention is applied to uncoiling deviation correction. An uncoiler 31 , a spiral magnetic deviation correction roller 32 , and a strip steel offset position sensor 33 . The deviation correction roller 32 guarantees that the uncoiled strip is centered and moves to the next procedure.

Abstract

An offset correcting method and apparatus for band steel features that the band steel is moving in such manner that it is tightly close to a cylindrical roller by a certain wrap angle, and said cylindrical roller is composed of an external hollow cylindrical roller made of non-magnetic material and an internal cylindrical roller able to generate spiral magnetic field, which can magnetically drivethe band steel to move. Regulating the direction of spiral magnetic field can correct the offset of band steel.

Description

(1) Technical field [0001] The invention relates to a method and a device for strip steel deflection correction. (2) Background technology [0002] The strip steel production line, whether it is a rolling mill or a pickling line, a galvanizing line, a tinning line, a coating line, a shearing line, etc., will have deviations during the operation of the strip, resulting in indentations on the surface of the strip Or warping and deformation will affect the quality of the cold-rolled sheet. In severe cases, the strip steel will be broken, the looper facilities will be damaged, and the unit cannot perform normal production. Therefore, various deviation correction control devices are required in the strip steel production line to ensure high-speed strip production, safety and increase productivity. [0003] There are many reasons for strip deviation, and they are random. Classified by type, there are mainly reasons for equipment, strip shape defects, misalignment of installation...
