Numerical study on influencing factors of molten iron flow field in blast furnace hearth
Numerical simulation of influencing factors of iron flow field in blast furnace hearth was carried out.The results show that the higher shear stress of molten iron is mainly concentrated in the lower part of the taphole.Increasing the utilization factor of blast furnace will increase the shear stress on the wall of furnace hearth.Under normal BF operation conditions,the porosity of dead column and the diameter of taphole have little effect on the shear stress of molten iron on the side wall of the furnace hearth.The shear stress of molten iron on the side wall of the hearth can be effectively reduced by increasing the depth of taphole and decreasing the angle of taphole.
