核反应堆压力容器用16MND5钢板的开发
|
摘要
介绍了某钢厂厚板生产线生产的核反应堆压力容器用16MND5钢板的生产工艺和过程控制情况,并分析了显微组织和力学性能。结果表明,通过EF-LF-RH-MC冶炼工艺生产的16MND5钢质较为纯净,从成分设计到工艺过程控制均比较合理。该钢板具有良好的综合力学性能和焊接性能,经过长时间的模拟焊后热处理后,钢板力学性能仍保持稳定,完全满足RCC-M标准要求。
The production process and the process control of 16 MND5 steel plate for nuclear reactor pressure vessel of steel factory thick plate production line are introduced,the microstructure and mechanical properties were analyzed. The results show that 16 MND5 steel has pure steel by EF-LF-RH-MC smelting process,the component design and the process control are reasonable. The steel plate has good mechanical properties and welding performance. After long time simulation of post-welded heat treatment,the mechanical properties of 16 MND5 steel plate are stable and completely meet RCC-M requirements.
