Kinetics experiment was conducted in a self-prepared kg-scale high temperature fluidized bed for 1-3mm ore fines reduction with hydrogen.The utilization rate of hydrogen decreases with reaction,which shows that the reactive speed is fast in the early reaction stage,but afterwards slower.The higher the reaction temperature,the more the utilization rate of hydrogen,but difference of the utilization rate is narrowed gradually with the increase in reaction time.Under the conditions of the first 20min and 750℃,the utilization rate of hydrogen is 9%,and the metallization degree reaches 84%,which shows that the speed of reduction reaction with hydrogen is very fast.With increase in hydrogen gas velocity,the metallization degree of iron ore fines increases linearly.So,in order to improve the productivity of facility,in case of hydrogen as reducing gas,much higher velocity of hydrogen can be allowed.With increase in the bed depth,metallization degree of iron ore fines decreases while the utilization rate of hydrogen increases gradually.The reaction temperature can lower to 700-750℃ with hydrogen as reducing gas,which is helpful to solve the sticking problems of fluidized bed.As for the reduction reaction of 1-3mm iron ore fines with hydrogen,its apparent activation energy is about 58.4kJ/mol in the fluidized bed experiment.
