Use of a Multi-sensor Technique to Monitor the Mould Oscillation in a Continuous Billet Caster

抄録

Producing a defect free product is most important in the process of continuous casting as the defect may propagate to the end product and also can increase the downgrading. Inadequate oscillation parameters as well as a defective oscillation may greatly affect the surface quality of the cast product. So monitoring friction along with the oscillation profile of the oscillator can lead to take corrective action when there is an increase in friction between the mould and strand or if there is any wear and tear in the machine components. In the present work a multi-sensor based mould oscillation monitoring system was developed to monitor the mould health as well as the friction between the mould and strand of a billet caster. Friction force was calculated for different carbon composition, type of lubrications and was co-related with the surface quality of billets. Also monitoring the mould health was able to detect problems in the machine and corrective action could be taken care of in time.
