Problems solved by technology

This leads to a large deviation in alignment. In actual production, the average alignment of each frame differs by 30-40mm, which leads to unstable rolling of strip steel and the shape of the plate cannot be guaranteed.
This has laid a hidden danger for the smooth flow of production.

Embodiment Construction

[0007] The present invention will be further described below in conjunction with embodiment:

[0008] A calibration method for a side guide plate of a finishing mill, characterized in that: the equipment involved in the calibration method includes a frame archway 1, an upper entrance guide 2, an entrance lower guide 3, a side guide plate A 5 on the operating side, and a transmission The side guide plate B 7 on the side, the calibration method is completed by the following steps:

[0009] The first step: the side guide plate A 5 and the side guide plate B 7 are installed on the slideway 4 with a beam 6 in the middle;

[0010] Step 2: Before calibration, check whether there is any foreign matter on the side guide A5 and side guide B 7 slideway;

[0011] Step 3: Open both sides of side guide plate A 5 and side guide plate B 7 to a certain extent at the same time, and manually close and open the side guide plate A 5 and side guide plate B 7 to test whether the movement is flexibl...

Abstract

The invention belongs to the technical field of steelmaking, and relates to a calibration method of a side guide plate of a finishing mill. The calibration method relates to a rack memorial archway, an inlet upper guide and guard, an inlet lower guide and guard, a side guide plate A on the operation side and a side guide plate B on the transmission side; and the calibration method comprises the following steps of 1), mounting the side guide plate A and the side guide plate B on slideways, and arranging a cross beam in the middle; 2), checking whether foreign matters exist on slideways of the side guide plate A and the side guide plate B or not before calibration; 3), simultaneously opening the two sides of the side guide plate A and the side guide plate B for a certain opening degree, andmanually closing and opening to test whether the side guide plate A and the side guide plate B are flexible or not; and 4), detecting whether mechanical jamming exists on the slideways or not. The calibration method has the characteristics of being simple, easy to operate, capable of avoiding production accidents, capable of ensuring stable production of a production line and the like.

Description

technical field [0001] The invention belongs to the technical field of steelmaking and relates to a calibration method for a side guide plate of a finishing mill. Background technique [0002] In the prior art, the centering degree of the finish rolling side guide plate of the 1750mm unit of the hot continuous rolling production line is due to improper measurement method and mechanical wear of the equipment. This leads to a large deviation in alignment, and the average alignment difference of each frame in actual production is 30-40mm, which leads to unstable rolling of strip steel and the shape of the plate cannot be guaranteed. This has laid a hidden danger for the smooth flow of production. . Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a method for calibrating side guide plates of finishing mills with the characteristics of simple method, easy operation, avoiding production accidents, and ensuring ...
