A new method for measuring the thickness of molten powder on the molten steel in the continuous casting (C.C.) mold was studied.The authors found that the molten powder thickness could be determined by using an eddy current sensor with two frequencies.This method is based on the difference in electric resistivity between the molten powder and the molten steel. The resistivity of the molten powder, though varying slightly with viscosity, is almost stable above the temperature of 1 300°C. As a result of the experiment, the measurement accuracy was found to be within ±1-2mm.The authors are now studying the relation between the molten powder behavior and the CC. operational conditions by using this method.
