从本世纪初到现在,经过几乎整整一个世纪的研究工作,可以说对钢中夹杂物有了较多的认识。人们已经知道,夹杂物作为钢的组成部分,主要是在冶炼和浇注过程中产生的;其尺寸和出现频率有可能减少,数量有可能控制;但人们同样了解到,无论炼钢技术怎样发展,钢中夹杂物总是会出现的。因此,近年来的夹杂物研究工作主要集中在两个方面:尽可能提高钢的清洁度;改变夹杂物的形态和分布。当然,为了推动夹杂物的研究,夹杂物分析技术也作为一个重要领域
From the beginning of this century to the present, after almost a century of research work, we can say that there is more understanding of inclusions in steel. It is already known that inclusions, as part of steel, are mainly produced during smelting and pouring; their size and frequency of occurrence are likely to be reduced and the quantity is likely to be controlled; but it is also understood that whatever the development of steelmaking technology, Inclusions in steel always appear. Therefore, in recent years, the study of inclusions mainly focus on two aspects: to improve the cleanliness of steel; change the shape and distribution of inclusions. Of course, in order to promote the study of inclusions, inclusions analysis technology is also an important area
