Determination of strand surface temperature and heat transfer during continuous casting*
Détermination de la température de surface sur ligne de coulée continue et du transfert thermique lors de la coulée continue
The embedded thermocouple technique for measuring strand surface temperatures has been developed and used to measure temperatures on British Steel casters. Mathematical modelling methods have been developed to derive from these measurements information on spray heat transfer, roll heat extraction and heat transfer from surplus spray water in the gaps between rolls and sprays. The analysis uses an inverse solidification model.
From the data, background heat transfer coefficients have been determined for the surplus water in the roll gap. This coefficient is larger after the spray, where water lies in the gap between spray and roll.
