Practice of Improving the Quality of Sintered Mineral Resources in Xinyu Steel No.4 and No.5 Units
Sintered ore from Xinyu Steel accounts for 75％～85％of the iron containing raw materials in the furnace,and the stability of sintered ore quality is crucial for the smooth operation of the blast furnace.Based on the goal of building a steel enterprise with millions of tons proposed by Xinyu Steel,it is required to significantly increase the production of blast furnaces,and to meet the needs of blast furnace materials,the production of sintered ore should also be correspondingly increased.Through optimizing the ore blending structure,improving equipment and facilities,increasing the temperature of the mixture,and solving the difficult problems in the production process such as material accumulation in the mixing hopper and returning to the ground,the effect is significant.The solid fuel consumption per ton of sintered ore has significantly decreased,and the utilization coefficient has been greatly increased,achieving good economic results.
