Dynamic superheat determination: A fresh approach

Dynamic tundish superheat can be obtained from continuous temperature measurement, in combination with liquidus prediction; however, quantifying the accuracy of the liquidus prediction is difficult without practical measurement. A new liquidus prediction and sensor measuring liquidus within the tundish have been devised and tested, substantially increasing confidence in the values obtained. Combining, in the same system, liquidus and continuous temperature measurements, delivered through wireless technology, with the integrated liquidus prediction provides an economical, accurate and reliable dynamic superheat value, enabling steelmakers to optimize casting superheat and move toward automated casting practices. Results have been compared to existing liquidus predictions. © 2019 Iron and Steel Society. All rights reserved.
