Abstract:In order to reduce sintering cost and energy consumption of sintering process, and improve the quality of sinter, we conduct experiments on optimizing the sintering proportion of South African rich ore fines, Brazilian ore fines, South African concentrate ore fines 1 and 2 in a steel company. The results show that the optimal ore matching scheme is No.6. Its proportion of Brazilian ore fines, South African rich ore fines and South African concentrate ore fines 1 is 15:70:15. The utilization coefficient is 2.66 t/(m2·h), tumbler index is 63.39%, RI and RDI+3.15 is 70.06% and 51.30%, respectively, and the value of molten drop performance "S" is 1 419 kPa·℃.
