(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 eigenfrequency identification, and realizes functions such as eigenfrequency calculation; Rolling Mill Gearbox Fault Viewer Board” to obtain shock fault signatures from vibration signals. Since the system has been running for more than 5 years, the risk of failure has been found many times, in order to ensure the safe and reliable operation of the rolling mill)
