Problems solved by technology
The contact between the correction roller and the surface of the metal strip may cause scratches on the surface of the metal strip, and in some occasions where the free section of the metal strip is long (such as loopers, annealing furnaces, etc.), the middle section of the metal strip cannot use the traditional roller type Correcting equipment, causing serious deviation, sometimes causing accidents such as edge scraping and broken belts, seriously affecting production

Embodiment Construction
[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0023] Please also see figure 1 and figure 2 , is a structural schematic diagram of the non-contact roller permanent magnet eddy current rectifying equipment for the strip continuous production line provided by the present invention. The non-contact roller permanent magnet eddy current rectification equipment of the strip continuous production line includes a strip 1, a roller 2 located on one side of the strip 1 and several permanent magnets 3 arranged on the circumferential surface of the roller 2, the roller 2 and the permanent magnet 3 and the strip 1 are set at intervals. Strip 1 along figure 1 run in the direction of the arrow.
[0024] The roller 2 is cylindrical, and its axis is parallel to the running ...

The invention relates to a non-contact roller type permanent-magnetism error correction device of a continuous strip production line. The device comprises a strip, a roller placed at one side of the strip at least and permanent magnets arranged in the circumferential surface of the roller, the roller and the permanent magnets are arranged separate from the strip, the axis of the roller is in parallel with the moving direction of the strip, the column number of the permanent magnets in the circumferential direction of the roller is an even number, and orientations of outward magnetic poles of the adjacent permanent magnets are opposite. The device carries out non-contact error correction, is free of wearing and noise, prevents the strip from scratch, the error correction force can adjusted smoothly, work is reliable.
Description
technical field [0001] The invention relates to a deviation correction device, in particular to a non-contact roller permanent magnet eddy current deviation correction device and method for a strip continuous production line. Background technique [0002] In the production process of continuous processing of metal strips, an important condition is to ensure that the metal strips run stably and centered on the production line, so as to provide a good foundation for the process. [0003] In actual engineering design, the "deviation" of the metal strip has always been a chronic problem that threatens the continuous processing process of the metal strip and the operation of the production equipment. The centering control during the running process of the metal strip has become an important topic in the research of the continuous processing technology and equipment of the metal strip. The current correction equipment is mainly the lateral movement correction of the uncoiler / coil...
