Method for adjusting verticality of rolling mill

Abstract

The invention discloses a method for adjusting the verticality of a rolling mill in mounting accuracy, and the method the following steps of: (1) erecting a piano line at a rolling center line of the rolling mill; (2) fixing a base at one side of a swinging tool on the base plate of a rolling mill rack or mounting the base on a steel levelling rule according to measuring requirements; (3) fixing two dial gauges on the base plate of the rolling mill rack or the steel levelling rule by virtue of a magnetic gauge stand, rotating the rocker arm of the swinging tool, and adjusting a sliding bearing arranged at a base at the other side of the swinging tool to cause the indications of the two dial gauges to be constant; (4) placing a third dial gauge at one lateral shaft end of the swinging tool, detecting the axial displacement of a shaft in a swinging process; and (5) mounting an inner diameter micrometer in the fixture hole of the swinging tool to cause the micrometric screw of the inner diameter micrometer to be exactly contacted with the rolling piano line of the rolling mill, reading the indication of the inner diameter micrometer, and calculating the verticality between the base plate of the rolling mill or two rolling mill memorial archways and the piano line at a rolling center. By adopting the method disclosed by the invention, the influence caused by accumulated errors is reduced.

Description

technical field [0001] The invention relates to a method for adjusting verticality, in particular to a method for adjusting the verticality of a rolling mill bottom plate, an archway and a rolling line. Background technique [0002] During the installation process of the rolling mill, the alignment of the bottom plate and archway of the rolling mill is a key process, especially when adjusting the verticality between the bottom plate, archway and the rolling line. A reference center line of the machine row, and then use the suspension piano wire and the pendant to align the reference center line of the machine row, and then use the inner diameter micrometer to find the parallelism between the bottom plate of the rolling mill, the archway and the piano line, so as to ensure that the bottom plate of the rolling mill, the archway and the Perpendicularity of the roll line. This alignment method has the following disadvantages: 1. Not directly measuring the verticality may cause ...

AI Technical Summary

Problems solved by technology

This alignment method has the following disadvantages: 1. Not directly measuring the verticality may cause the measured data to be inaccurate

2. There are errors in each step, resulting in excessive cumulative errors

3. Causes an increase in manpower, material resources and time

4. In the adjustment of the verticality between the bottom plate of the rolling mill stand, the archway and the rolling line, the installation accuracy cannot be achieved
