Application of the Quick Immersion Technique for Temperature Measurement of Steel Bath in Ladle

On the continuous immersion pyrometry of molten steel-III

Abstract

Much data of measurements by the continuous immersion pyrometry in the steel making process are treated by the statistical method. It is shown that a considerable scattering exists in the values of temperature drop from tapping to pouring. So it would be difficult to predict the bath temperature at certain time from the tapping temperature only. This scattering is produced mainly by the tapping operation. The quick immersion technique in ladle is developed as a supplementary method to the continuous immersion pyrometry. The results obtained by this technique support our previous conclusions.
