Operational experience with a mathematical model for temperature prediction in secondary steelmaking

A previous study has reported the development of flow and thermal model for gas purged ladle and validation of the same by comparison with literature. This paper presents further development of an integrated process model from tapping at LD to teeming at tundish location. The model was tuned and validated with plant data. The model shows a match of temperature within (+/- 5 degreesC) between prediction and measurement for most of heat data. The model was then used to carry out sensitivity test for the various important process parameters in order to find out quantitative influence of these on steel temperatures. The findings have been reported here.
