| description | The invention discloses a low-alkalinity refining slag system for removing sulfur elements, a preparation method and a molten steel refining method, and belongs to the technical field of refining slag steelmaking, and the refining slag system comprises the following components in percentage by mass: 45%-70% of CuO, 5%-15% of SiO2, 10%-25% of MgO, 5%-10% of Al2O3 and 2%-10% of CaF2. According to the method, the content of the sulfur element in the molten steel and the number of dotted inclusions can be reduced, the purity of the molten steel is improved, and the quality of the smelted steel is excellent.
本发明公开了一种脱除硫元素的低碱度精炼渣系、制备方法及钢液精炼方法，属于精炼渣炼钢技术领域，所述精炼渣系成分含量按照质量百分比计算，包括：CuO 45％～70％、SiO2 5％～15％、MgO 10％～25％、Al2O3 5％～10％、CaF2 2％～10％。本发明能够降低钢液硫元素的含量和点状夹杂物的数量，提高钢液的纯净度，炼出的钢材质量优异。 |
