EFFECTS OF PACKED STRUCTURE AND OPERATION CONDITIONS ON LIQUID FLOW BEHAVIOR IN BLAST FURNACE HEARTH
The circulating flow of molten iron is an important reason that results in the erosion of blast furnace hearth.In order to prolong the campaign life of blast furnace,it is necessary to analysis the flow state of molten iron.The three-dimensional mathematical model at steady state which takes the standard k-e and porous zone model into consideration is applied to simulate the flow field under different conditions.The results showed that floating of the deadman did strengthen molten iron circulating flow.Increasing the deadman diameter will increase the erosion of hearth and bottom.Deepen the depth of the taphole and reduce the taphole diameter can reduce the circulating flow.Effect of the taphole angle from 10° to 15° is not significant.The results can be used to provide guidance for protecting the blast furnace hearth.
