随高炉腹煤气指数冶炼探索与实践

EXPLORATION AND PRACTICE OF HIGH FURNACE GAS INDEX

高炉炉腹煤气指数是高炉操作的一项重要工艺参数。炉腹煤气指数的上限受原燃料条件、炉型、高炉操作方式和渣铁排放状态等因素的综合影响,3号高炉经过长期不断的探索,通过一系列的技术手段,实现了在高指数下的稳定顺行,取得了较好经济效益。

Blast furnace gas index is an important parameter for blast furnace operation. The upper limit of belly gas index is affected by the factors such as raw and fuel conditions, furnace type, operation mode of blast furnace and slag and iron discharge status. The 3 号 blast furnace has achieved stable and smooth operation under high index by a series of technical means, and achieved better economic benefits.
