The invention discloses a tension leveler driving roller running state monitoring system and a fault diagnosis method, and belongs to the technical field of analysis on the running state of a continuous casting machine fan-shaped section tension leveler driving roller. The monitoring system comprises a signal acquisition system S1, a module selection system S2, a data analysis system S3 and a fault reminding system S4, wherein the signal acquisition system S1 comprises a temperature sensor, a tension sensor and an optical-electric encoder; the module selection system S2 comprises a standard database of three difference tension leveling forces, namely an arc measurement tension leveling force, a free-opening tension leveling force and a casting tension leveling force; the data analysis system S3 performs matching comparison on data detected by the signal acquisition system S1 in real time and data of the standard database of the module selection system S2, and judges the running state of the device; and the fault reminding system S4 helps users to perform troubleshooting by displaying fault information on a display. The monitoring system provided by the invention meets requirements that a continuous casting machine analyzes the running state of the driving roller at difference working states, and achieves advanced judgment on the full life circle fault of the continuous casting device; and meanwhile, a layer-by-layer analysis method is developed, that is, by a method of analyzing the total tension leveling force of the tension leveler and the tension leveling force of each driving roller layer by layer, precision location of a fault position of the driving roller is achieved.
Description
Technical field [0001] The invention belongs to the field of analysis methods for the operating state of the driving roller of a continuous casting machine segment stretch and straightening machine, and specifically belongs to a running state monitoring system and a fault diagnosis method for the driving roller of a stretch straightening machine. Background technique [0002] The segment stretch straightening machine of the continuous casting machine is an important part of the continuous casting machine. It consists of an arc section, a straightening section, a horizontal section and a basic frame support structure. The main function is to pass the hot cast billet in the solidification process through the fan section. The inner arc frame is guided by the continuous radius of the driving roller, and the casting slab is straightened at the inflection point, and the thickness of the slab is adjusted by the hydraulic soft reduction system. If the segment tension leveler fails during...
