Abstract 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. Industrial test shows that by using the new modifier, TFe content of the slag reduced by 1.31%, while MgO content increased 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。
