为实现转炉除尘资源的循环利用，提出采用除尘灰、炼钢污泥、废镁砖、碳化硅及粘接剂按一定比例混合压制成球后用于转炉终点炉渣改质的思路，并通过工业试验验证了终渣调整剂的炉渣改质效果。工业试验表明，采用新研制的终渣调整剂后,调渣前后炉渣全铁质量分数平均降了1.31%，MgO质量分数平均上升了0.71%；与原改质剂相比，起渣时间平均提前了0.11 min，溅渣时间缩短了0.12 min，溅渣护炉效果更好。新型终渣调渣剂的成功研制，不仅实现了二次资源的循环利用，更是提高了转炉冶金效果，降低了生产成本。

In order to realize the cyclic utilization of converter dedusting resources, precipitator dust, converter slug, waste magnesite brick, carborundum and adhesives were mixed according to a certain proportion to make modifier to change the final slag of converter, and industrial test was carried out to verify the modifing effect of the new modifier. In-dustrial test shows that by using the new modifier, TFe content of the slag reduced by 1.31%, while MgO content in-creased by 0.71%; compared with the original modifier, slag rising time and splashing time were shortened by 0.11min and 0.12min respectively. The new modifier obtained a better slag splashing effect. The successful development of the new modifier not only made the secondary resource cyclic utilization but also improved the metallurgical effect and reduced cost of production.
