(The high-speed wire rod mill network monitoring system is used to monitor the vibration information of the roughing mill and the finishing mill. The software part integrates spectrum analysis, wavelet analysis and characteristic frequency identification, and realizes functions such as characteristic frequency calculation; Rolling Mill Gearbox Defect Viewer Plate" to obtain shock defect characteristics from vibration signals. Since the system has been running for more than 5 years, it has found many shortcomings and risks. In order to ensure the safe and reliable operation of the rolling mill)
