Rolling Mill Condition Monitoring and Fault Analysis LMM
Rolling mill status monitoring is to monitor the main process variables involved in the rolling mill in real-time to determine whether a fault occurs. The fault diagnosis based on the rolling mill mainly studies how to detect, separate, identify and recover the fault of the rolling mill. 01 Rolling mill status monitoringThe F3 mill upper work roller vibration acceleration testing time-domain parameters on field is shown in Table 2.It can be seen that although axial force is less than 1% of the rolling force, roller axial vibration acceleration amplitude is close to vertical acceleration and lateral acceleration, so the axial force (caused by rollers cross) Impact Analysis of Roller System Stability for Four-High Mill
