Technical Field
[0001] The utility model relates to the technical field of hot-rolled strip steel inlet guides, and specifically discloses a hot-rolled strip steel inlet guide. Background Art
[0002] Each unit of the hot strip finishing mill is equipped with an entry guide device for the smooth introduction of the rolled strip. The entry guide device is driven to the roll changing position by a hydraulic cylinder when changing the working roll and the support roll. The entry guide device is provided with an adjustable side guide plate, and the side guide plate is adjusted by a hydraulic cylinder. The hydraulic cylinder is equipped with a displacement sensor, which is used to monitor the opening of the side guide plate in real time when the width of the incoming strip changes, so as to meet the needs of the incoming strip. In addition, the working conditions at the entry guide are relatively bad (there is a lot of cooling water flushing, high temperature, high humidity), and the action is frequent. Therefore, the normal action, action accuracy and rapid response of the side guide plate are necessary to improve the rolling stability and product quality.
[0003] In the prior art, a hot-rolled strip finishing mill entrance guide device is disclosed in the patent with announcement number CN214160896U, which includes two groups of guide assemblies, which are relatively arranged on both sides of the strip travel path at the entrance of the finishing mill, and the guide assemblies include a mill guide and a side guide plate arranged on the mill guide, a spray pipe is laid on the upper surface of the side guide plate, and a plurality of nozzles for spraying cooling water onto the surface of the strip are provided on the spray pipe.
[0004] In the above scheme, the oil cylinder is arranged above the base and is completely exposed to a large amount of cooling water flushing, high temperature and high humidity environment, resulting in a high loss rate. In addition, the hinge between the oil cylinder and the side guide plate is very likely to loosen, affecting the normal movement, movement accuracy and rapid response of the side guide plate.
