摘要
研究了安龙钢铁公司LF冷态钢渣的渣系组成和硫容量,对影响钢水脱硫的热力学因素和动力学因素进行了分析讨论,并结合炼钢实际和冶炼品种特点,在精炼渣氧化性、曼内斯曼指数、氟化钙含量等方面提出了LF精炼脱硫的技术措施。介绍了如何循环利用LF冷态钢渣脱硫的工艺技术,为钢铁行业提供了一项较为实用的节能降耗途径。
The present paper studies the compositions and sulphur content of the LF cold steelmaking slag series in the Anlong Iron ＆ Steel Co. , Ltd. and analyzes and discusses about thermodynamic and kinetic factors affecting the liquid steel desulphurization and puts forward the technological measures in respect of desulphurization of LF refining, in connection of the practical steelmaking conditions and characteristics of steel grades, in order to improve the oxidizability, Mannesmann index and amount of CaF2 in the slag. It also introduces technologies of how to reclaim the cold state steelmaking slag of the LF furnace for desulphurization purpose and therefore provides a more practical approach to the energy saving and consumption reduction for the iron and steel sector of China.
