An Online Diagnosis Method for Finishing Mill

Abstract

The invention relates to an on-line diagnosis method for a finishing mill, belonging to the technical field of high-line finishing mill point inspection. The technical solution of the present invention is to divide the online faults of the finishing mill into three types, the first type is bearing damage faults, the second type is gear engagement faults, and the third type is lubrication failure faults; according to the bearing installation position and gear meshing position in the precision Three spot inspection positions are set on the rolling mill; quantitative analysis and real-time monitoring are carried out by comparing the parameter data of the normal operating state of the finishing mill with the data of the three types of fault states based on the data measured at the three points. The beneficial effect of the invention is that it can predict possible equipment failures in advance and formulate maintenance plans in advance, avoiding equipment accidents, providing a reliable guarantee for the stable operation of the finishing mill, and prolonging the service life of the equipment.

Description

technical field [0001] The invention relates to an online diagnosis method for a finishing mill, which belongs to the technical field of high-efficiency finishing mill point inspection. Background technique [0002] As the key process of high-speed wire rod production, the finishing mill will have bearing damage faults, lubrication failure faults and gear meshing faults during operation, which affect the stable operation of the finishing mill. There is no standard point inspection method in the prior art and the finishing mill The spot inspection method will be different depending on the cause of the fault. It is difficult to find complex problems with the general spot inspection method, and it is impossible to find the signs of the fault in advance to avoid major equipment accidents, and the fault diagnosis of the finishing mill needs to consider many operating parameters. General It is difficult for technicians to get started, which not only increases the difficulty of spo...
