Inlet centering guide and guard device of Q345B-Ti hot-rolled strip steel finishing mill set

Abstract

The invention discloses an inlet centering guide and guard device of a Q345B-Ti hot-rolled strip steel finishing mill set, and relates to the technical field of Q345B-Ti strip steel finishing mill centering guide and guard. The inlet centering guide and guard device comprises a base, strip-shaped receding holes are formed in the upper end of the base, a first guide block is arranged on one side ofthe upper surface of the base, a second guide block is arranged on the other side of the upper surface of the base, fastening bolts are inserted into the inner side of the first guide block and the inner side of the second guide block, one end of each fastening bolt penetrates through the corresponding strip-shaped receding hole, and the lower end of each fastening bolt is in threaded connectionwith a threaded block. Compared with the prior art, the inlet centering guide and guard device has the beneficial effects that the guide blocks can be tightly pressed on the base through the fasteningbolts, the positions of the guide blocks are fixed through the pressure of threaded knobs, the displacement of the guide blocks is limited through the base, the impact force generated when the guideblocks collide with a steel belt is borne by the base, then the impact force borne by hydraulic cylinders is reduced, and the service life of the hydraulic cylinders is prolonged advantageously.

Description

technical field [0001] The invention relates to the technical field of centering guides for the finishing rolling of Q345B-Ti strip steel, in particular to a centering guide device for the inlet of a Q345B-Ti hot-rolled strip finishing mill. Background technique [0002] When adjusting the width of the steel belt inlet in the existing entrance, the guide block is driven by a hydraulic cylinder to move, so the guide block can be moved to change the width of the entrance according to the difference of the steel belt, and The hydraulic cylinder restricts the position of the guide block, but the steel belt will have an impact when it contacts the guide block, and the hydraulic cylinder will resist the impact to avoid the displacement of the guide block, which will affect the hydraulic cylinder after long-term use service life, leading to an increase in cost. Contents of the invention [0003] The purpose of the present invention is to provide a Q345B-Ti hot-rolled strip finis...
