Using Electric Field to Monitor the Continuous Casting

Detecting the internal dynamic structure in opaque production line helps to obtain essential information for steering the processing parameter. This work reports the implementation of electric field and magnified percolation effect to a continuous casting mold. It is able to indicate the change of internal dynamic structure such as the solid shell thickness, nozzle condensation, structural integrity of coating film, slag entrapping and inclusion states. The method does not suffer from the penetration limit from skin effect of electromagnetic field and has potential to detect the structural health of engineering component made by multiphase alloys.
