Method, system and storage medium for online detection of position change of roll central axis

Abstract

The invention discloses a method and system for on-line detection of roller central axis position changes and a storage medium. The method comprises the following steps that a laser signal of a reference point is acquired, wherein the reference point is arranged on the end face of a shaft head of a roller; the motion track of the reference point is obtained according to the laser signal; and the motion track of a point to be detected is obtained according to the motion track of the reference point and the actual positional relationship between the reference point and the point to be detected,wherein the point to be detected is located at the center of the end face of the shaft head of the roller, and the center of the circle is at the center axis of the roller. The method, the system andthe storage medium solve the technical problem that the roller central axis position changes in the rolling process cannot be detected in real time due to a plurality of detection restrictions in theprior art.

Description

technical field [0001] The invention relates to the field of detection of key parameters of rolling mill equipment, in particular to a method, system and storage medium for on-line detection of the position change of the center axis of a roll. Background technique [0002] More than 90% of metal materials are finished by rolling, and rolling technology occupies a very important position in metallurgical industry and national economic production, so it is necessary to improve rolling quality. [0003] The main factors affecting rolling are the precision of the rolling mill archway, the precision of the roll itself and the matching precision of the bearing and the roll. The window of the rolling mill archway establishes a stable and accurate position for the roll bearing seat, and its dimensional accuracy is affected by uneven foundation settlement, running wear and corrosion, and poor maintenance accuracy. The decline in the dimensional accuracy of the rolling mill archway w...
