Abstract

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.
