Abstract
This paper reports the experimental results on heat transfer performance of a newly suggested temperature equalizer with the radiative converter for a slab in the continuous casting direct rolling process. The present temperature equalization is based on the effective energy conversion method between gas enthalpy and thermal radiation using a porous media. The model temperature equalizer used is about one fifth of the actual one its dimensions. To simulate the continuous casting direct rolling process in the experiment, the uniformly preheated model slab was first cooled by thermal radiation, and subsequently fed into the temperature equalizer. By measurements of transient slab temperatures, it is proved that the radiative converter equalizes the slab temperature quickly owing to local heating of the slab edge. Furthermore, estimation of the overall energy balance in the temperature equalizer demonstrated that efficient temperature equalization is feasible if the available energy flowing out of it is recovered.
