  • Detection of roller damage and/or misalignment in continuous casting of metals
    Patent number: 6845286
    Abstract: A method for detecting roller irregularities during on-line continuous casting of a metal comprises; i) continuously monitoring the changes in the mould level over time; ii) identifying large periodic influences affecting the mould level versus time function and their frequency, iii) comparing the frequency of the periodic influences of step ii) with predicted frequency harmonics based on a normal operation of the casting process and highlighting by comparison of the predicted and actual frequencies characteristics indicative of irregularities in roller behavior.
