Correctable tension steering pinch roll for auxiliary coiling of steel strip and method of use thereof

Abstract

The invention relates to the field of metal rolling, in particular to a roller capable of achieving deviation correction, tension and turning pinching and for strip steel auxiliary coiling and an application method of the roller. The roller capable of achieving deviation correction, tension and turning pinching and for strip steel auxiliary coiling comprises a fixed rack (1) and rotary supports (2), and is characterized in that a swing rack (3), an upper rack (4), lower tension rollers (5), a fixed turning roller (6), an elevation roller (7), an upper tension roller (8), a tail press roller (9), a pinch roller (10), press-down hydraulic cylinders (11) and a deviation correction hydraulic cylinder (12) are further included; the two ends of the swing rack (3) are arranged on the rotary supports (2); and the deviation correction hydraulic cylinder (12) is connected with the fixed rack (1) and the swing rack (3). The application method of the roller capable of achieving deviation correction, tension and turning pinching and for strip steel auxiliary coiling is characterized by sequentially comprising the following steps of belt penetrating, operating and tail throwing. The roller is simple in structure, convenient to use and accurate in control, and the rolling quality is improved.

Description

technical field [0001] The invention relates to the field of metal rolling, in particular to an offset-correctable tension-turning pinch roll for auxiliary strip coiling and a method for using the same. Background technique [0002] In the prior art, there are known tension rollers, rectifying rollers and steering pinch rollers that assist the coiler to coil the strip steel. These devices are all arranged in front of the coiler, and their functions are respectively to increase the After the tension, the correction roller corrects the deflection of the strip in time, and the steering pinch roller provides power for the strip head and can change the direction of the strip head, so that the strip head smoothly enters the coiler for coiling. The existing tension roller is mainly of S-shaped structure, and its disadvantage is that it changes the height of the strip steel passage line, and needs to be matched with a steering roller to restore the strip steel passage line height; t...

AI Technical Summary

Problems solved by technology

The existing tension roller is mainly of S-shaped structure, and its disadvantage is that it changes the height of the strip steel passage line, and needs to be matched with a steering roller to restore the strip steel passage line height; the existing deviation correction roller has two types: vertical type and horizontal type structure, the disadvantage of the former is that the height of the strip steel passage line is changed, and the disadvantage of the latter is that the amount of deviation correction is small

The existing steering pinch rollers are mainly in the form of eccentricity of the upper rollers. This structure can only change the running direction of the belt head, and cannot properly bend the tail of the strip so that the tail of the strip can fit better on the outer ring of the steel coil.
