Anti-winding guide plate locating method and rolling mill

Abstract

The invention relates to an anti-winding guide plate locating method and a rolling mill designed based on the locating method. The locating method comprises the steps that first locating components are arranged on roller bearing pedestals, second locating components are arranged on an anti-winding guide plate, and the positions of the first locating components on the bearing pedestals can be adjusted; and before the anti-winding guide plate needs to be located, the positions of the first locating components are calibrated, and the first locating components can meet the conditions that in the process of driving the anti-winding guide plate to get close to a roller, the first locating components and the second locating components cooperate, and therefore the anti-winding guide plate is blocked at the target working position. According to the above locating method, the simple mechanical locating method is adopted for replacing traditional detection instruments and control systems, and theproblems that at present, in the industry, when the anti-winding guide plate is located by conventionally depending on a displacement sensor and a proximity switch, failures are prone to happening under the severe working environment, consequently, precision is lost, and repair and maintenance are complex are avoided; and position calibration of the first locating components can be completed in the roller offline coping procedure, and the work efficiency of online equipment and production continuity are completely not influenced.

Description

technical field [0001] The invention belongs to the technical field of steel rolling, and in particular relates to a positioning method for an anti-winding guide plate and a rolling mill. Background technique [0002] In the cold rolling mill, in order to prevent the strip from being wound around the roll and seal the strip channel when the strip is broken, a specific guide plate needs to be designed to be close to the roll body or even directly pressed against the roll during rolling. body, when the roll is replaced, the guide plate needs to be kept away from the roll; the guide plate is also called the anti-winding guide plate. [0003] Since the roll diameter is constantly changing with the grinding process during the use of the roll, the technological requirement stroke of the anti-wrapping guide plate also changes accordingly. In order to achieve this goal, a lot of work is required in terms of mechanical equipment and electrical control. [0004] In order to achieve ...
