Abstract:In order to further study the temperature field distribution of the submerged arc furnace lining, ANSYS analytical software was used to simulate the simplified model of the real furnace lining. By changing the furnace temperature and convection heat transfer coefficient, the temperature of furnace wall was obtained, which was compared with the actual measurement data to verify the reasonableness of the simulation data. The result showed that the temperature distributions of different refractory materials in furnace lining were different. The temperature of furnace wall increased with the increase of temperature in the furnace, while decreased with the increase of convection heat transfer coefficient. And the slope of the curve about the variation of the furnace wall temperature with the convective heat transfer coefficient was decreased from 0.13 to 0.06. When the curve slope was approximate to zero, the convective heat transfer coefficient no longer had any effect on the change of the furnace wall temperature, then the optimized convective heat transfer coefficient was obtained. The percentage of the simulated data in the measured data was in the range of 3%- 8%, the temperature of the furnace wall was reasonably reflected by the simulation data, which could provide the basis for the design of the insulation construction and the selection of refractory materials.
