A monitoring system for ladle rotary table of continuous casting machine

Abstract

The invention belongs to the technical field of condition monitoring of a continuous casting machine, and discloses a monitoring system for the large ladle turret of the continuous casting machine. The monitoring system comprises a vibration monitoring unit, a displacement monitoring unit, communication buses, an industrial personal computer and a sound and light alarm, wherein the vibration monitoring unit comprises a plurality of vibration sensor sets; the vibration sensor sets are arranged around the rotating tower bearing of the continuous casting machine to form a plurality of condition monitoring points; the displacement monitoring unit comprises a plurality of displacement sensors; the displacement sensors are arranged at the condition monitoring points; the vibration sensors and the displacement sensors at the condition monitoring points are all connected with the industrial personal computer through the communication buses; the sound and light alarm is connected with the industrial personal computer. According to the monitoring system, the vibration parameters and displacement values of point monitoring pints are obtained by setting the condition monitoring points; the monitoring system is convenient for recording and maintenance, logical analysis and judgment are carried out at the same time to give an alarm signal, and the production safety is maintained.

Description

technical field [0001] The invention relates to the technical field of continuous casting machine state monitoring, in particular to a continuous casting machine ladle rotary table monitoring system. Background technique [0002] The slewing bearing (or rotating bearing) is an important part on the ladle turret of the continuous casting machine, and its safe and stable operation is very important for the normal operation of the ladle turret. During the working process of the slewing bearing, there will be failures such as roller wear and tear, roller raceway damage, nylon cage crushing and other failures. [0003] Due to objective reasons such as heavy production tasks and poor on-site working environment, the use status of the slewing bearing is usually checked. The oil test method (spectral analysis) can only be used to observe the metal content and judge the wear of the slewing bearing. Production poses hidden dangers.
