| Abstract: | According to the thermofluid dynamics and enthalpy-porosity method of computational fluid dynamics,a 3-D steady-state tapping model of blast furnace hearth was developed,including solidification and phase transition of hot metal and slag.The cooling conditions for hearth and bottom were transformed reasonably by equivalent coefficient of convective heat transfer.The velocity field,temperature field and skull figure in a blast furnace hearth were computed and analyzed. The skull data and flow character of ho... |
