文摘The hit rate of narrow composition in LF furnace of steelmaking plant is one of the most important economic and technical indexes in steelmaking process. In this paper, aiming at LF furnace of steelmaking plant of Delong Iron and Steel Co., Ltd., through measures such as reducing slag oxidizability, improving qualified rate of steel samples and optimizing argon blowing effect in ladle, the hit rate of narrow composition in LF furnace is optimized and improved, which effectively reduces the consumption of steel and alloy, reduces the production cost, and at the same time, narrows the fluctuation range of molten steel composition and plays a certain role in promoting the stability of strip steel performance.
