Abstract
高炉装料制度是调整炉内煤气合理分布的主要手段，是高炉操作者不断探索优化的重要课题。本文从布料角度、矿批、料线、布料精度控制等几个方面入手，对京唐高炉在不同时期，不同装料制度下，高炉各冶炼指标的变化进行统计分析。研究得出京唐特大型高炉装料制度应遵循以下几个方面：1) 采用中心加焦w型煤气分布布料；2) 坚持大矿批冶炼；3) 尽量减小料线深度；4) 降低炉料偏析。 Charging system as an important topic of the blast furnace operators is the primary way which can improve the gas distribution of blast furnace. In this paper, the charging system of blast furnace is studied from several aspects, such as charging pattern, charging angle, stock line and so on. From those aspects at different times, the change of the blast furnace smelting index was analyzed. It is concluded that the charging system of large blast furnace should follow the following aspects: 1) charge bulk coke at center to get “w” type cohesive zone; 2) to keep large batch of ore; 3) try to reduce the stock line; 4) to reduce the burden segregation.
