Fluidization quality optimization of new side-stirred fluidized iron smelting
To solve the problems of slugging,gully flow,and bond loss caused by uneven gas-solid distribution in the traditional fluidized iron-making process,a hot experimental platform of side stirring fluidized bed was established.The effects of reduction gas composition,agitator speed,and reduction temperature on the reduction process of iron ore powder were studied by single factor experiment.The changes in bed pressure drop and flue gas composition with time in the fluidized bed were investigated.The results show that the reduction degree of iron increases with the increase of CO percentage.The gas-solid fluidization quality of the side-agitator fluidized bed is better than that of the non-agitator fluidized bed,and the best speed is 160 r/min.The optimal reduction temperature is 850℃.
