前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結構和起草規則》的規

定起草。

本文件代替GB/T11880—2008《模鍛錘和大型機械鍛壓機用模塊技術條件》，與GB/T11880—2008相

比，除結構調整和編輯性改動外，主要技術變化如下：

—更改了模塊化學成分偏差的要求，對面積的區間劃分作出了調整，擴大了Mo、V、W成分的

范圍（見表1，2008年版的表2）；

—更改了模塊熱處理的要求，根據不同原材料規定了相應的硬度值（見4.3.1，2008年版的

3,9）；

—增加了截面尺寸規格，新增了4種寬度、4種高度規格（見表4）；

—更改了鍛造工藝的要求（見4.2，2008年版的3.6）；

—更改了內部質量的要求（見4.3.3，2008年版的3.7、3.8、3.10）；

—增加了化學成分、金屬流線、低倍組織、非金屬夾雜物、表面質量、尺寸的試驗方法（見表5）；

—更改了超聲檢測方法（見表5，2008年版的4.5）；

—更改了組批規則，使其適用于所有檢驗項目（見6.1，2008年版的4.3）；

—增加了各個檢驗項目取樣數量、取樣部位的要求（見6.2）；

—增加了復驗和判定規則（見6.3）。
