摘要：
The influence of desulphurizing agents affecting the surface activity of the sulphur on the desulphurizing rate was investigated in wear-resisting steel grades. Components forming thermodynamically more permanent compounds with sulphur than iron does, may be used as desulphurizers. In the present test, mixtures of rare earths, carbide, silicocalcium, fluorspar and lime were employed. Due to low price and permanent availability, the use of rare earths is possible in Vietnam.
