Problems solved by technology

These five major parts have an impact on the accuracy of guide assembly. There are too many loss links in the entire precision composition, and the control is difficult. Therefore, problems such as flash seams and inclinations often occur in guides during rolling, especially for lower guides. Obviously, it is very easy to cause accidents of stacking steel between the rolling parts

Abstract

The invention provides an H-shaped steel rolling mill guide pre-tightening device, which relates to the technical field of metallurgical equipment, and comprises an ejector rod and an ejector spring sleeved on the ejector rod, the lifting device is arranged on the ejector rod, and the relative position of the lifting device and the ejector rod can be changed; wherein the jacking spring is located above the lifting device, and one end of the jacking spring makes contact with the lifting device.When the H-shaped steel rolling mill guide pre-jacking device is used, it can be guaranteed that a guide face is tightly attached to a roller, steel piling caused by guide flash seams is avoided, and the rolling stability is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a guide pre-tightening device for an H-shaped steel rolling mill. Background technique [0002] The finishing guide adopts the beam assembly bracket mode to fix the guide. The offline part of the guide system includes five parts: the guide, the beam, the bracket, the beam seat, the eccentric pin, and some small parts including the gasket group and the slide plate. part. These five major parts have an impact on the accuracy of guide assembly. There are too many loss links in the entire precision composition, and the control is difficult. Therefore, problems such as flash seams and inclinations often occur in guides during rolling, especially for lower guides. Obviously, it is very easy to cause the accident of stacking steel between the rolling parts. Contents of the invention [0003] The object of the present invention is to provide a guide pre-tightening dev...
