Breakthrough in Increasing Efficiency and Reducing Consumption in Xichang Steel & Vanadium No.1 BF
Facing the increasingly tough conditions in environmental protection,cost and resources,Xichang Steel & Vanadi-um develops the technologies for increasing efficiency and reducing consumption in its No.1 BF.To overcome the bottle-necks,such as low charge grade,large amount of slag produced and high slag viscosity,measures in the quality control of raw material & fuel,and measures in BF operating system optimization are taken;the former ones mainly include manage-ment of the coke quality,stopping the usage of lump ore and increasing the rate of pellets;and the latter ones fall on coordi-nating the charge distribution and blasting operation,selecting appropriate heat system and slagging system to keep the smel-ting intensity not less than 1.35t/(m3·d),and keep[Ti]+[Si]within 0.25％-0.35％.As a result of above measures,the BF productivity in the first half year of 2023 increases by 0.15-0.25t/(m3·d),the coal rate increases by 10-20kg/t,and the fuel rate decreases by 10-15 kg/t compared with that in June-July 2022.
