Abstract

Тhe results of the heterophase interaction of nanoparticles of refractory phases with iron melts containing harmful impurities (sulfur, antimony, tin, and copper) are studied and generalized. It is shown that the degree of the removal of impurities (~0.05 wt %) in the Fe–S, Fe–Sn, Fe–Sb, and Fe–Cu systems after the introduction of nanoparticles ranges from 10 to 37 rel %. As a result of the interaction of nanoparticles with impurities of the metal melt, the formation of ensembles with new surface properties is proposed. It is shown that the redistribution of ensembles in the melt and their removal to the phase interface can be represented as a two-stage process.

与耐火材料接触的铁熔体中耐火相的外源纳米颗粒与有色金属表面活性剂杂质的相互作用

研究并归纳了难熔相纳米粒子与含有害杂质（硫、锑、锡和铜）的铁熔体的异相相互作用结果。结果表明，引入纳米粒子后，Fe-S、Fe-Sn、Fe-Sb 和 Fe-Cu 体系中杂质（约 0.05 wt %）的去除率为 10% 至 37%。由于纳米粒子与金属熔体中的杂质相互作用，形成了具有新表面特性的集合体。研究表明，集合体在熔体中的重新分布以及它们被移除到相界面的过程可以分为两个阶段。
