摘　　要：非金属夹杂物检验标准GB/T 10561-2023已修订完成,为了更好地实施新标准,针对新标准的修订内容,从术语定义、原理、测定方法、结果表示、计算公式、评级图谱方面进行了详细的解析。新标准主要修订内容如下:增加了术语和定义部分,修改了夹杂物定义和特征描述;增加了析出相类评定要求以及化学特征表示方法,将非金属夹杂物级别细化为10个级别,明确了取样要求,更改了钢管的取样方法,明确了夹杂物起评尺寸;修改了测定方法,给出了显微镜B法的扫描方式,在结果表示方面修改了夹杂物类型和系列划分界限不清晰的问题;新标准更改了夹杂物测量值和夹杂物级别计算公式,并重新绘制了标准评级图,相比GB/T 10561-2005版标准,新发布的GB/T 10561-2023标准更加完善。The inspection standard for non-metallic inclusions(GB/T 10561-2023)has been revised.In order to more precisely implement the revised standard,in this paper,we provide a detailed analysis on the revised contents of the new standard GB/T 10561-2023“Determination of Non-metallic Inclusion Content in Steel by Micrographic Method Using Standard Diagrams,”including the terminology definitions,principles,determination methods,results representations,calculation formulas,and rating maps.The major revisions of the new standard are summarized as follows:the terms and definitions section is added;the definition and characterization of inclusions are revised;requirements to evaluate the precipitated phases is required and the methods for describing their chemical characteristics are amended;the level of non-metallic inclusions is subdivided into 10 levels;the sampling requirements clarified,the sampling and schematic diagram for steel pipes modified,and the least size of inclusions for evaluation is clarified.The determination method was modified,and the scanning mode of the microscope B method was given.In terms of results presentations,the unclear classification of inclusion types and series boundaries was revised.The new standard has changed the calculation formula for inclusion measurement values and inclusion levels,and redrawn the standard rating diagram.Compared to the GB/T 10561-2005 version,the newly released GB/T 10561-2023 standard is more complete.
