“…This method involves the desulfurizer floating on the liquid surface of the hot metal into the hot metal through the rotation of the blades, so that the desulfurizer can contact and react closely with the hot metal, thus realizing desulfurization. When the type of desulfurizer and the condition of molten iron are stable, the degree of mixing and dispersion of desulfurizer in molten iron directly affects the desulfurization efficiency [2,3] . For KR desulfurization, the purpose of stirring is to eliminate the concentration difference, so the desulfurization efficiency can be expressed by studying the stirring efficiency of the paddle [4] .…”

KR (Kanbara Reactor) method is the mainstream desulfurization method in hot metal pretreatment. The mixing efficiency of three kinds of blades, namely, the regular four-blade propeller, the spiral three-blade propeller and the double-layer regular four-blade propeller, was studied by numerical simulation method. The results showed that the mixing time of the double-layer regular four-blade propeller was 7.3% shorter than that of the regular four-blade propeller, and 38% shorter than that of the spiral three-blade propeller. Through the analysis of the axial velocity distribution in the molten iron, it was found that the axial velocity of the molten iron in the double-layer regular four-blade propeller agitator was larger.
