Practice of Smelting High Alkalinity Slag from Blast Furnace
In order to stabilize blast furnace production and actively change operational thinking,the 10th blast furnace of the Ironmaking Division of Xinyu Iron and Steel Group Co.,Ltd.began exploring and practicing high alkalinity slag smelting methods in May 2024.This article studies and discusses the effects of high alkalinity slag smelting on blast furnace smelting parameters,soft melt zone position,and alkali and zinc discharge performance.Based on actual smelting parameters,suitable operating methods for high alkalinity slag smelting are explored,and a series of reasonable operating systems such as slag making,cooling,and charging are summarized for high alkalinity slag smelting,which maintains the long-term smooth operation of the blast furnace and achieves good economic and technical indicators.
