摘要
为了在铁水预脱硅、脱磷工艺中利用不锈钢炼钢厂含铬镍混轧铁皮及回收有价金属,按不同配比用含铬镍铁皮替代烧结矿粉及氧化铁皮,配成不同成分的脱硅、脱磷剂,进行了熔化性实验和扫描电镜观察。研究发现,在改善脱硅脱磷剂的配比情况下,含镍铬混轧铁皮可完全或部分替代氧化铁皮及烧结矿粉用于铁水脱硅脱磷。
In order to utilize Cr-Ni bearing rolling scales produced in stainless steel works in the desilicification and dephosphorization process and recycle valuable metals, melting experiments of desilicification and dephosphorizing agents and dephosphorization experiments of hot metal were carried out with dephosphorization fluxes of various compositions prepared with various proportion of Cr-Ni bearing rolling scales instead of sintering ore and then observed by the scanning electronic microscope. The results show that by proper adjustment of the proportion of the desilicifier and dephosphorizer, the Cr-Ni bearing rolling scales can be completely or partially substituted for iron scale and sinter used in desilicification and dephosphorization of hot metal.
