| Summary: | Carbon combustion rates can be altered with different particle sizes of solid fuel, which can directly affect the mineralization of iron ore sintering. A quantitative relationship between coke size and iron ore sintering indexes was studied using a mixture regression design method and simplex-lattice design. Also, the effects of optimal coke particle size on the cold intensity and productivity of the sinter were verified by sinter pot tests and analytical studying the sintering mineral structure. Results show that changing and optimizing the proportion of different coke sizes (<1 mm, 1 mm–3 mm, 3 mm–5 mm, >5 mm) can satisfy the need for sintering production to indexes. It has important significance to reduce solid fuel consumption and improve the yield and quality of sinter. |
