On-line temperature measuring device for surfaces of rolls of strip rolling mill and testing method of on-line temperature measuring device

Abstract

The invention relates to an on-line temperature measuring device for the surfaces of rolls in a strip rolling process in the field of strip rolling mill production in the metallurgy industry and a testing method of the on-line temperature measuring device. The on-line temperature measuring device is characterized by being composed of a base, an adjusting bolt, a support, a thermometer, a clamp, a protective sleeve and an air blowing device. The support and the base are connected through the adjusting bolt, the thermometer is tightly clamped by the clamp, the clamp is connected onto the support through a fixed bolt, the installation angle of the thermometer can be adjusted by the adjusting bolt as required, the protective sleeve covers the outside the thermometer, the base is connected with balance beam supports on two sides of the upper portion of an upper roll and track beams on two sides of the lower portion of a lower roll, the air blowing device is connected onto the base through a fixed bolt and close to the thermometer as far as possible, and protective plates are installed on the track beams and cover the upper portion of the temperature measuring device arranged below for surfaces of rolls.

Description

technical field [0001] The on-line temperature measuring device and testing method for the roll surface of a strip rolling mill according to the invention relates to an on-line temperature measuring device for the roll surface during the rolling process of a plate in the field of strip rolling mill production in the metallurgical industry. Background technique [0002] At present, in the process of strip rolling, the heat of the rolled piece and the heat released by the deformation of the rolled piece will heat the roll and cause the roll to expand, causing thermal crowning in the axial direction, which not only affects the strip The quality of the shape, and because the surface of the roll is repeatedly subjected to rapid heat from the strip and rapid cooling caused by cooling water, air, etc., fatigue damage is extremely prone to occur. Therefore, in the rolling process, in order to control the temperature of the rolls, set the best cooling conditions, and master the heat ...

AI Technical Summary

Problems solved by technology

It is used to solve the existing problems in the prior art: 1. The measurement results are inaccurate and the error is relatively large; 2. The measurement is performed after the equipment is shut down, and the detection timeliness is poor; 3. The analysis results can only improve the cooling conditions in a directional manner, but cannot be quantified; 4. Completely Relying on manual participation in detection, low efficiency and other issues
