DEVELOPMENT OF A 'CONDITION MONITORING SYSTEM FOR STEEL SLAB CASTER

摘要

Accordingly, there is provided a condition monitoring system for steel slab caster which adapts multiple sensors for monitoring the friction level, by measuring the friction between the mould and the solidifying slab including monitoring the health of the oscillator for any abnormality in operation. This system adapts at least four numbers of Tri-Axial Accelerometers. Acceleration value is collected in the X, Y and Z direction using the tri-axial accelerometers which are placed at the corners of the continuous casting mould table. The acceleration value is collected for both casting and no casting conditions adapting a data acquisition system. A process module is used to do the post processing of data to calculate the friction and analyze the data collected from the accelerometers for any abnormality in the machine health. The difference between the force during casting and force during no casting with the same frequency of oscillation gives the friction value which appears due to the interaction between mould and the solidifying strand. FFT of the collected data is done in the three directions to find if there is any fault in continuous casting machine that is problem with eccentric cam, worn bearing, non-sinusoidal nature of oscillation.
