一、前言以钢中所含的氧化物为主的非金属夹杂物是钢成型时发生裂纹和产生疲劳断裂的起因,它会导致钢的成型性和疲劳寿命变差,同时它还是导致轧制时发生线状缺陷的原因等,因此对产品质量有很大的影响。夹杂物的粒度一般在超微米至数百微米,钢的各种特性在大多数情况下受一定粒度以上的夹杂物所控制。另外,只要知道夹
I. INTRODUCTION Non-metallic inclusions mainly composed of oxides contained in steel are the cause of cracking and fatigue fracture in steel forming, which leads to deterioration of formability and fatigue life of steel, and at the same time it leads to rolling When the occurrence of linear defects, etc., so the product quality has a great impact. The size of the inclusions is generally in the range of nanometers to hundreds of micrometers, and the properties of the steel are controlled in most cases by inclusions of a certain size or larger. In addition, just know the clip
