Abstract
The present invention relates to a strip steel deviation technology, in particular to a non contact strip steel deviation technology method and a device. A no-roll strip steel deviation technology is characterized in that a couple of electromagnets are arranged above two sides of the strip steel in a place where the strip steel is easy to deviate or has requirements to the deviating quantity. When a strip steel deviating quantity detecting system detects the deviation of the strip steel, a detected signal is changed into an electric signal; the deviating quantity and deviating direction is gained by gathering and operating the electric signal through a computer; the clearance between the strip steel and the electromagnet is changed by controlling an excitation current of two electromagnets; then the deviation of the strip steel is corrected. At the same time, the distance between the electromagnet and the strip steel is detected by a displacement sensor; then the detected signal is input into a computer controlling system; the excitation current of the electromagnet is controlled by the output signal made by the computer controlling system after operating. The present is simple in structure, high in response rate, precise in deviation deviation and easy to realize the computer controlling.
Description
(1) technical field
The present invention relates to the strip steel deviation technology, relate in particular to non-contacting strip steel deviation method and device.
(2) background technology
In modernized continuous belt steel is produced, owing to equipment is installed, the reason of the aspects such as plate shape of band steel, deviation phenomenon can appear in the band steel of high-speed cruising, make belt steel surface occur scratching, reduced product design, also can cause production and equipment breakdowns such as broken belt when serious, reduce labor efficiency, increase troubleshooting time and expense.Therefore, need be on output strip line mounting strap steel deviation correcting device.
