Steering slip method of heavy rolling mill archway in confined space

Abstract

The invention particularly discloses a turning sliding method for a heavy rolling mill house in a restricted space. The turning sliding method is characterized by comprising the steps that a sliding rail is made and installed, and a sliding device is installed; the heavy rolling mill house is unloaded in place; the heavy rolling mill house slides once; the heavy rolling mill house is jacked up; turning sliding preparation is made; the heavy rolling mill house slides for the second time; and four hydraulic jacks are used for moving the heavy rolling mill house down onto a sliding beam, the jacks are removed, a chain fall is hung on a transverse lifting lug of the sliding beam, and thus the house turns and slides in place. Compared with a traditional heavy rolling mill sliding method, the turning sliding method has the following advantages that the sliding device and the sliding rail are simple in structure, manufacturing and machining are simple and convenient, and use is convenient. Through the turning sliding method, the heavy rolling mill house can slide in front, back, left and right directions, smooth in-place sliding of the heavy rolling mill house in the restricted space is ensured, and the sliding process is safe and reliable.

Description

technical field [0001] The invention relates to the field of installation of heavy rolling mills, in particular to a method for steering and sliding of heavy rolling mill arches in a limited space. Background technique [0002] With the country's increasingly strict requirements on energy consumption and environmental protection, adjusting structure, reducing costs, eliminating backward products, improving quality, and developing high-end products are becoming the goals pursued by domestic iron and steel enterprises. In the current domestic production line, more than half of the low-end products are configured to produce, and most of them have problems such as low dimensional accuracy, unstable performance, and difficulty in thin-scale production. In the face of increasingly fierce market competition, the technical transformation and upgrading of the rolling mill production line is a wise choice. Therefore, the upgrading project of the rolling mill production line has becom...

Problems solved by technology

Currently commonly used sliding devices are not only complex in structure, but usually can only achieve sliding in the same linear direction

In this way, the sliding operation of the traditional heavy-duty rolling mill archway is obviously not safe and efficient enough
