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...
