| Abstract: | By finite difference, the article analyses heat transfers at the unsteady state of plate and spheroid lining, provides calculating formulea of temperature on the interfaces and surface, as well as temperature field in plate lining. The formulea of temperature field and surface temperature of spheriod lining are also given. Some examples are calculated by computer. The results express that on the surface of furnace wall,the temperature difference between calculation and testing is 8.6% only. |
