摘要
自１９９１年１１月以来，３号高炉炉料结构发生了重大变化，国外球团矿配比逐渐提高到２４％，自产球团矿配比为１３％。为了适应炉料结构的变化，探索出了上、下部调节相结合的适宜操作制度并取得了显著的冶炼效果。
Since November of 1991,the burden mix for No.3 blast furnace has changed considerably.The ratio of imported pellet has increased up to 2 4%,and that of self-supported pellet is 13%.For adapting to the change of burden mix,the operation regulation which combines the upper control of charge weight and changing schedule with lower control of blast velocity has been established with significant economic benefit.
