| Abstract: | The mathematical model of heat transfer in heat retaining process of hot charging and rolling is developed The results show that the calculated temperature is consistent with the actually measured values and the model is capable of predicting the temperature of slab in heat preserved process and providing reference temperature The heat preservation pit has evident effect on the slab temperature and the slabs should be kept in pit no more than 10 hours Shortening the transferred time in heat preserving tunnel and keeping the tunnel covered as much as possible are effective measures to enhance the delivering temperature |
