摘要
稀土能与钢液中的氧、硫产生极强的结合、与磷、砷、锑、铋、铅、铜等低熔点杂质发生交互作用 ,同时能改善夹杂物的形态和大小 ,细化晶粒 ,均匀分布。
Rare earths play important role in alloying of steels. It can strongly combine with oxygen and sulfur in the melt and interact with some imparties with low melting point ,such as, phosphorus, arsenic, antimony, bismuth, lead, copper and so on. Alos, it can improve the shape and size of impurities, refine grain and make the distribution of phase in alloy.
