Mathematical model of heat transfer on solidification is established combined with the practical production situation of the continuous caster. The thickness of solidified slab shell in secondary cooling spot is determined by nail-shooting experimentation. Heat transfer coefficient on different secondary cooling zone is modified by nail-shooting result, thus the accuracy of the mathematical model is ensured. Comparing practical result with that calculated by mathematical model, it shows that modified model can simulate the heat transfer and solidification process, which can provide accurate end solidification spot and serve for soft reduction.

Solidification heat transfer in continuous casting slab was simulated with the business software CALCOSOFT. The position on solidification end point which obviously effect on soft reduction was predicted and verified by nail—shooting technique. It is shown from the numerical simulation that the casting speed affected the position significantly: the solidification end point moved backward 3 or 4m as the casting speed increased by 0.2m /min, while the casting temperature has little effect that the solidification end point moved backward only 0.2 or 0.25mm as it increased 6°C or 7°C.

Cooling Model

Secondary cooling is one of the important techniques of continuous casting. A mathematical model for heat transfer during solidification in continuous casting was established in researching on influence of the solidifying process on slab quality. The dynamic secondary cooling system has been analyzed with consideration of the principles, nozzles arrangement method and mathematical model of solidification process. The model was applied on some continuous casting machines. It indicates that the dynamic cooling model is better than conventional ones.

A mathematical heat transfer model was built to simulate temperature, shell growth and phase transformations in continuous casting based on the technical conditions of the bloom caster of some steelmaking plant. The simulation result is coincided with the measurement. The effects of the operation parameters including casting speed, bloom size and steel melt superheat on the solidification process were discussed and the means of enhancing the bloom temperature was brought forward. The research results have been applied in the practical manufacture process to compute the best casting speed, to control the flow rate of secondary cooling water and to optimize the spray pattern of secondary cooling zone. The bloom quality and productivity could be improved.
