HL-2M真空室支撑耳轴锻件的研制

Research on forging and manufacturing process of HL-2M vacuum vessel support trunnion

介绍了HL-2M真空室支撑耳轴的整体异型锻件的制造工艺流程,从锻件本体上切取试样进行了材料检测。检测结果表明,所试制的耳轴锻件表面和芯部位置的屈服强度分别为1100MPa和1057MPa,两位置的材料晶粒度等级都达到4级,各项力学性能指标均满足设计要求。

The manufacturing process of integral special-shaped forgings of the HL-2M vacuum vessel support trunnion was introduced, and the material testing was conducted by cutting the samples from the forging body. The test results show that the yield strength of the surface and core position of the trunnion forgings are 1100MPa and 1057MPa respectively, the grain size grade of those two positions can be up to grade 4, and all mechanical performance parameters can meet the design requirements.
