摘　　要：在实验室条件下用金相显微镜、扫描电镜对钢液钙处理前后钢样进行观察,研究了钢中夹杂物在形态、分布、数量、尺寸、组成等各方面的变化。据此探索钢中形成有利夹杂物的途径与方法,为实际生产提供理论依据及数据参考。Under laboratory conditions, steel samples before and after calcium treatment were observed by metalloscope and scanning electron microscopic. The observations involved with changes of inclusions in shape, distribution, quantity, size, composition, etc. According to the research results, the approach and method for forming favorable inclusions in molten steel are discussed , which can provide theoretical basis and data reference for actual production.
