【摘要】：防甩击大梁为核电站防甩钢结构的核心部件,具有构件密集、螺栓群多、重型构件多、制作难度大、焊接要求高等特点。着重介绍防甩击大梁在的组装流程、焊接、制孔、运输过程中的精度控制,以及采取的工艺措施。根据现场安装情况,对于加工制作方案和工艺措施既达到设计要求,又达到精度控制的目的。
[Abstract]:Anti-jetting beam is the core component of the anti-dump steel structure of nuclear power station. It has the characteristics of dense components, more bolts, more heavy-duty members, more difficulties in manufacture and higher requirements for welding. This paper emphatically introduces the assembly process, welding and hole making of the anti-jetting beam. The precision control in the transportation process and the technological measures taken. According to the field installation, both the design requirements and the precision control are achieved for the machining and manufacturing schemes and the technological measures.
