青钢3号高炉(418 m~3)在建成开炉后的一段时间内,高炉生产不稳定,没有达产。后来,通过采取提高烧结矿质量、采用合理炉料结构、调整高炉基本操作制度等措施,实现了达产目标,高炉各项技术经济指标逐步改善,利用系数达到3.2～3.3,综合焦比降到490 kg/t。
During the period after blast furnace opened at No. 3 blast furnace (418 m ~ 3) of Qinggang Iron and Steel Co., Ltd., blast furnace production was not stable and there was no production. Later, through the measures of improving the quality of sinter, adopting reasonable charging structure and adjusting the basic operation system of blast furnace, the technical target of blast furnace was achieved. The technological and economic indexes of blast furnace were gradually improved, the utilization coefficient reached 3.2-3.3, the comprehensive coke ratio dropped to 490 kg / t.
