摘要/Abstract

摘要： 以SA508-3钢制核电蒸发器上封头锻件为研究对象,针对上封头的产品特点,对其淬火方案进行了优化。通过描述旋转运动的多重参考系(Multiple reference frame,MRF)模型,得出淬火槽中冷却介质的流动状态。结果表明,在淬火槽内增设圆锥台型导流罩并配置内腔抽水泵后,上封头内外表面水流速度基本均超过0.3 m/s,内腔平均流速提升至约0.6 m/s,流动死区显著消除。淬火后外壁平均硬度达到34.75 HRC,且其内外壁硬度极差和标准偏差均小于其他方案,表明该方案处理上封头在硬度水平和均匀性方面均最优,整体性能表现最佳。

Abstract: Taking the upper head forging of nuclear power evaporator made of SA508-3 steel as the research object, the quenching method was designed and optimized based on its characteristics. By employing the multiple reference frame (MRF) model to describe the rotational motion, the flow state of the cooling medium in the quenching tank was obtained. The results indicate that by adding a conical flow guide and installing an internal pumping system in the quenching tank, the water flow velocity on both the inner and outer surfaces of the upper head generally exceeds 0.3 m/s, while the average flow velocity in the cavity increases to approximately 0.6 m/s, the stagnant flow zone is effectively eliminated. After quenching, the average hardness of the outer wall reaches 34.75 HRC, and both the hardness difference and standard deviation between the inner and outer walls are smaller than those observed in other schemes. This demonstrates that the upper head treated by this scheme is optimal in terms of hardness level and uniformity, exhibiting optimal overall performance.
