Interface Heat Transfer and Friction in Continuous Casting

Brian Thomas and Ya Meng

Continuous Casting Consortium

Heat transfer in continuous casting molds is controlled primarily by heat conduction across the interface between the solidifying steel shell and the water-cooled copper mold. A comprehensive model, CON1D, has been developed to predict this heat transfer, including mass and momentum balances on the interfacial powder layers, superheat delivery from the turbulent liquid pool, and gap formation between the shell and the mold walls. Plant and lab experiments are being conducted to measure interfacial heat transfer in the continuous casting mold. These are needed to obtain fundamental interfacial property data, so that the model can become a fully predictive tool to solve quality problems and interpret mold thermocouple and friction signals, including both steady (time-averaged) and transient phenomena.
