A leveling button fault monitoring device for a finishing mill and a finishing mill

Abstract

The invention belongs to the technical field of finish rolling, and discloses a leveling button fault monitoring device for a finish rolling machine. The device comprises a linear displacement sensorand a monitoring controller, wherein the linear displacement sensor is used for being arranged on the finish rolling machine and monitoring the linear displacement of a finish rolling HGC cylinder, the monitoring controller is connected with the linear displacement sensor, obtains the linear displacement of the finish rolling HGC cylinder, compares with the linear displacement with a first displacement threshold value and outputs a finish rolling HGC cylinder control instruction to a finish rolling machine controller. The finish rolling HGC cylinder control instruction comprises action continuing and action stopping. When the linear displacement of the finish rolling HGC cylinder is larger than the first displacement threshold value, the monitoring controller outputs an action stopping instruction; and when the linear displacement of the finish rolling HGC cylinder is smaller than or equal to the first displacement threshold value, the monitoring controller outputs the action continuing instruction. The monitoring device can monitor the non-upspring fault of a finish rolling machine leveling button, and can achieve fault repair.

Description

technical field [0001] The invention relates to the technical field of finish rolling, in particular to a leveling button fault monitoring device for a finish rolling mill and the finish rolling mill. Background technique [0002] Finishing mills are widely used in the field of steel rolling technology, and have a non-negligible effect on the quality of strip steel. Roll gap adjustment is a routine operation of the finishing mill, which is used to adjust the roll gap between the upper and lower work rolls, and plays a vital role in the quality of the strip rigidity. [0003] However, in actual production, due to structural failure, oil stains and other reasons, the leveling button may not pop up abnormally, resulting in unreliable roll gap adjustment failure; at the same time, because the pressing stroke of the button itself is small, it is often difficult for the operator to find it. As a result, the strip steel deviation is serious, resulting in a pile of steel accidents....
