一、前言钢中非金属夹杂物影响钢的性能。尤其是缺陷性非金属夹杂物,它可以导致机械性能显著下降。因此对缺陷夹杂物进行认真的探索,了解其性质和来源,已成为当前冶金学科中的一项重要课题。影响缺陷夹杂物形成的因素很复杂。虽然国内外许多冶金工作者对此做过一些论述,但由于冶金过程是一个十分复杂的物理化学过程,加之受检测手段的限制,要完全搞清楚缺陷夹杂物的性质和来源,目前还有不少困难。尽管如此,我们还是对缺陷夹杂物的性 I. Introduction Non-metallic inclusions in steel affect the performance of steel. Especially defective non-metallic inclusions, which can lead to a significant decrease in mechanical properties. Therefore, it is an important issue in current metallurgy that the serious exploration and understanding of the nature and origin of defects inclusions. Factors that affect the formation of defects inclusions are complex. Although many metallurgists at home and abroad have made some elaboration on this issue, since the metallurgical process is a very complex physical and chemical process, combined with the limitations of the testing methods, it is necessary to fully understand the nature and source of the defect inclusions Less difficult. Nevertheless, we are still on the nature of defects inclusions
