An analysis of the temperature field in the refractory feeder of a horizontal continuous billet casting machine

Conclusions A mathematical model of the process of formation of the front of solidification of the billet skin in the refractory feeder of a horizontal continuous casting machine taking into consideration possible changes in the geometric and thermophysical parameters of the refractory has been developed.An algorithm and a program have been set up making it possible to calculate the temperature field in the refractory feeder taking into consideration the front of solidification of the billet skin. Using the program developed the temperature field was calculated for a graphite-containing refractory in teeming of 45 steel. The calculations made agree with experimental results on wear of the refractory.The data obtained makes it possible to explain the wear of the refractory in the zone of contact with the mold and also to optimize the configuration of the working portion of the horizontal continuous casting machine refractory feeder.Translated from Ogneupory, No. 6, pp. 36–40, June, 1988.
