Abstract
Aiming at the special operating condition of long-term slow-wind production faced by No.2 blast furnace at Luoyuan Mingang Ironmaking Plant immediately after its commissioning,this paper systematically summarizes the practical process of achieving furnace condition stability through comprehensive operational adjustments.Due to production capacity constraints,the blast furnace had long been operating under a controlled production rate of 30%～40%,which led to a series of problems such as insufficient hearth activity and frequent furnace condition fluctuations.To address these issues,the operation team implemented a series of measures in terms of operational procedures,raw material and fuel management,and off-furnace operations.The practical results show that these measures effectively addressed the challenges of slow-wind production,maintained smooth operation of the blast furnace under low smelting intensity,and gradually reduced the fuel ratio.This provides valuable reference for the operation of similar blast furnaces under non-design conditions.关键词
