Slide bar type slab pusher for strip mill

Abstract

The invention relates to a sliding-rod-type slab pushing device for a strip rolling mill. The sliding-rod-type slab pushing device is mainly used for solving the technical problem that as for a rolling mill, excessively short slabs cannot be conveyed into a working roller seam through a roller way of a rack roller to be rolled. According to the technical scheme, the sliding-rod-type slab pushing device for the strip rolling mill comprises upper crossbeams, upper hinging supports, a swinging pushing plate, a sliding plate, a hydraulic cylinder, a sliding rod, rotary rings, vertical pipes, pushing plates and lower hinging seats, and the upper hinging supports are arranged in the middle of the bottom face of the upper crossbeam; one end of the swinging pushing plate is hinged to the second upper hinging support, a sliding groove is formed in one edge of the middle of the upper surface of the swinging pushing plate, the sliding plate is mounted in the sliding groove of the swinging pushingplate, one end of the hydraulic cylinder is hinged to the first upper hinging support, and the other end of the hydraulic cylinder is hinged to a hinging seat arranged on the sliding plate; the sliding rod penetrates through a hinging hole formed in the other end of the sliding plate, the two ends of the sliding rod penetrates into the rotary rings, and the rotary rings are inserted into the vertical pipes to form rotary pairs; the vertical pipes are fixed to one ends of the pushing plates; and the other ends of the pushing plates are hinged to the lower hinging seats above rack roller bearing seats.

Description

technical field [0001] The invention relates to a sliding bar type slab pushing device for a strip rolling mill, which belongs to the technical field of metallurgical equipment. Background technique [0002] The rolling of the strip is to send the slab into the roll through the rack roll installed inside the rolling mill archway, and sometimes some shorter slabs are rolled, because the gap between the last roll table of the rack roll and the work roll There is a certain distance, resulting in a shorter slab length that is less than the distance between the rack roll table and the rolls, so that the slab is separated from the drive of the rack rolls and cannot bite into the rolls. At this time, other external forces are required to push the shorter slabs billets to complete normal rolling. Contents of the invention [0003] The purpose of the present invention is to solve the technical problem that the rolling mill cannot use the stand roller table to send the slab into th...

Problems solved by technology

[0003] The purpose of the present invention is to solve the technical problem that the rolling mill cannot use the stand roller table to send the slab into the work roll gap to complete the rolling because the slab is too short, and to provide a sliding rod type slab pushing device for a strip mill. The device can assist the short slabs to quickly enter the work rolls for rolling
