Influence of Cerium and Aluminum on Solubility of Oxygen in Liquid Steel

Abstract

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.
