Влияние церия и алюминия на растворимость кислорода в жидкой стали

Abstract

Построены поверхности растворимости компонентов в металлических расплавах для системы Fe–Ce–Al–O. Показано, что в области достижимых концентраций кислорода, церия и алюминия возможно блокирование поверхности химически активных неметаллических включений. Выполнен анализ сравнительной раскислительной способности церия и алюминия путем построения диаграмм расходов активных металлов на рафинирование стали. Установлена бóльшая раскислительная способность церия по отношению к алюминию. Surfaces of solubility of components in metal melts are drawn for the Fe–Ce–Al–O system. It is shown that in the achievable range of oxygen, cerium and aluminum concentrations blocking of the surface of chemically active nonmetallic inclusions is possible. The analysis of comparative deoxidizing ability of cerium and aluminum is carried out by drawing diagrams of consumption of active metals for steel refinement. It is established that cerium has higher deoxidizing ability than aluminum.
