在研究低铬白口铸铁时曾用不同钾盐与钠盐作变质剂,发现它们均能促使这种铸铁中的碳化物团球化。本文对这种铸铁在凝固与热处理阶段的球化机理作了初步探讨。
In the study of low chromium white cast iron used different potassium salt and sodium salt as a modifier and found that they can promote the cast iron in the ball of the ball. In this paper, cast iron in the solidification and heat treatment stage of the ball made a preliminary discussion.
