A Method of Feeding Conditions Monitoring of Journal Bearing in Tandem Cold Mill

Abstract

This paper presents a real-time hydrodynamic lubricant feeding conditions monitoring system for journal bearing in tandem cold mill to avoid online burning accident. A new kind of sensor connector has been developed to perform as a measuring section applied with nondestructive testing technology. The hydrodynamic lubricant feeding conditions in the tandem cold mill have been characterized. The monitoring results show that the hydrodynamic lubricant feeding conditions have been proved to be good indicators for the safety production. This real-time hydrodynamic lubricant feeding conditions monitoring system can be used as a long-term monitoring platform and provide an early warning for the tandem cold mill's abnormal performance.
