首钢长钢8号高炉煤气流分布调控实践

Practice of Gas Flow Distribution Control in No. 8 Blast Furnace of Shougang Changgang

对首钢长钢8号高炉近几年调控煤气流的措施进行总结,从送风制度、原燃料改善、装料制度入手,对煤气流的三次分布进行调控,使煤气流在高炉内合理分布,技术经济指标良好,实现了高炉长期稳定顺行的目标。

This paper summarizes and analyzes the measures of regulating gas flow in No.8 blast furnace of Shougang Changgang in recent years,and combs out that the tertiary distribution of gas flow is regulated from the air supply system,raw fuel improvement and charging system,so as to achieve the purpose of reasonable gas flow distribution and long-term stable and smooth operation of blast furnace and good technical and economic indexes.
