前 言
本文件按照GB/T 1.1—2020《标准化工作导则 第1 部分：标准化文件的结构和起草规则》的规
定起草。
本文件代替GB/T 11880—2008《模锻锤和大型机械锻压机用模块技术条件》，与GB/T 11880—2008 相
比，除结构调整和编辑性改动外，主要技术变化如下：
更改了模块化学成分偏差的要求，对面积的区间划分作出了调整，扩大了Mo、V、W成分的
范围（见表1，2008年版的表2）；
—
更改了模块热处理的要求，根据不同原材料规定了相应的硬度值（见4.3.1，2008年版的
3,9）；
—
—增加了截面尺寸规格，新增了4种宽度、4种高度规格（见表4）；
—更改了锻造工艺的要求（见4.2，2008年版的3.6）；
—更改了内部质量的要求（见4.3.3，2008年版的3.7、3.8、3.10）；
—增加了化学成分、金属流线、低倍组织、非金属夹杂物、表面质量、尺寸的试验方法（见表5）；
—更改了超声检测方法（见表5，2008年版的4.5）；
—更改了组批规则，使其适用于所有检验项目（见6.1，2008年版的4.3）；
—增加了各个检验项目取样数量、取样部位的要求（见6.2）；
—增加了复验和判定规则（见6.3）。
