摘　　要：A new additive to save energy in the sintering process was developed The addition of additive accelerates the emission rate of volatiles and decreases the ignition temperature by the effect of cocatalyst in sintering process Moreover, because the additive acts as the active carrier of oxygen, the quantity of oxygen is greatly increased in sintering ores, loading to enhance the efficiency of combustion and improve the quality and production of the sinter ores When the amount of additive and coke is 0 2% and 5 5%, the sintering indexes reach the optimum values Compared with no additive sintering experiments, the addition of the additive greatly catalyze the combustion of solid fuel, i e , utilization efficiency increased by 7 30%, solid fuel consumption decreased by 16 22%A new additive to save energy in the sintering process was developed The addition of additive accelerates the emission rate of volatiles and decreases the ignition temperature by the effect of cocatalyst in sintering process Moreover, because the additive acts as the active carrier of oxygen, the quantity of oxygen is greatly increased in sintering ores, loading to enhance the efficiency of combustion and improve the quality and production of the sinter ores When the amount of additive and coke is 0 2% and 5 5%, the sintering indexes reach the optimum values Compared with no additive sintering experiments, the addition of the additive greatly catalyze the combustion of solid fuel, i e , utilization efficiency increased by 7 30%, solid fuel consumption decreased by 16 22%
