THE INVESTIGATION OF A HEAT TRANSFER MODEL AND EXPERIMENTS ON THE RADIATION TUBE

According to the experiments and the heat transfer model of the radiation tube, the distribution and change regularity of the tube wall temperature and the combustion gas temperature are investigated under different operating parameters. The results calculated through the model are in accord with those from experiments. These results can guide the radiation tude operation to extend the life period of the tube and to raise the heating quality of the strip steel.
