Based on the actual production of Liusteel 360 m2 sintering machine,aiming at the high energy consumption of sintering process,the thickness of the material layer was increased from 750 mm to 820 mm after optimization and adjust-ment from the upgrading of sintering process of thick material layer,the transformation of micro-negative pressure sintering,the reduction of gas consumption,the reduction of air leakage rate of the truck,and the improvement of sealing property of the ring cooler.The results show that the rotary drum strength of the sinter is increased by 0.76％,the return rate is reduced by 2.19％,and the process energy consumption is reduced from 51.93 kgce/t to 40.51 kgce/t.
