Vertical rolling mill vertical roll centering distance measuring device and measuring method thereof

Abstract

The invention provides a vertical rolling mill vertical roll centering distance measuring device, and belongs to the technical field of production control equipment of a vertical rolling mill. The invention further relates to a measuring method of the vertical rolling mill vertical roll centering distance measuring device, a base protrusion block I (7) is arranged on the upper surface of a devicebase (4) of the vertical rolling mill vertical roll centering distance measuring device, a base protrusion block II (9) is arranged on the upper surface of the device base (4), and an end face threaded hole (13) is formed in a base end face surface I (12) of a groove surface (11). A left and right leveling screw rod (14) is arranged in the end face threaded hole (13) in a screwed mode, and a device socket (5) is arranged to be a structure capable of movably arranging in a groove part (10) in a clamping mode. According to the vertical rolling mill vertical roll centering distance measuring device and method, the distances between an operating side vertical rolling mill and a transmission side vertical rolling mill and a vertical rolling mill physical center line correspondingly can be measured, accurate data is provided for the calibration of the vertical rolling mill, and the measurement safety is effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of vertical roll mill production control equipment, more specifically, it relates to a measuring device for vertical roll centering distance of vertical rolling mill, and the invention also relates to a measuring device for vertical roll centering distance of vertical rolling mill method. Background technique [0002] The CSP production line has an vertical roller mill before the finishing mill. Every time the vertical roller is replaced, repaired, and TDC is restarted, the operator must calibrate the vertical roller mill. When performing calibration work in the prior art, it is necessary to place the vertical rollers on both sides (operating side vertical rollers and transmission side vertical rollers) at a certain distance in advance. The ruler is based on the two sides of the middle beam between the two vertical rollers, and measures the distance to the roller surface of the driving side vertical roller ...

AI Technical Summary

Problems solved by technology

However, such a measurement method is very dangerous to measure, and the ambient temperature is high, and the operator is prone to slip and fall into the flushing ditch below

At the same time, there are other components above the middle beam that affect the operator's measurement, and accurate measurement values ​​cannot be obtained, causing errors in the calibration of the vertical rolls, unable to provide accurate data for the control of the vertical roll mill, affecting the shape control, and Shape accuracy, leading to price concessions

In severe cases, the guide guard on the entrance side of the steel billet or steel plate frame will cause piles of steel

As for the equipment, the position of the guide on the entrance side of the finishing mill cannot be accurately controlled, the pressure measured by the guides on both sides is uneven, and the vibration of the rolling mill increases, which aggravates the wear of the equipment.

In this way, the actual demand cannot be effectively met
