铝件浸液式非标淬火设备的研制

Development of non-standard immersion quenching equipment for aluminum parts

通过介绍铝件淬火工艺基本原则、铝件在水介质中浸液式淬火可能出现的问题以及换热系数与淬火介质温度和流速的关系,为铝件浸液式淬火设备的非标设计提供科学依据。根据本团队研制的非标铝件浸液式淬火设备工程应用中遴选典型案例,分析其在设计和产业化过程中遇到的一些关键问题,阐明了淬火时保证铝件预期性能的前提下减少畸变的解决方法。

The principles of quenching process of aluminum parts,potential problems of aluminum parts in the quenching process and the relationship between heat transfer coefficient and temperature as well as the cooling velocity of quenchant were introduced. And a scientific basis of immersion quenching equipment of aluminum parts for customization was provided. Finally,several typical engineering examples are analyzed based on some critical issues during the design and industrialization,which are selected from dozens of cases of immersion quenching equipment of aluminum parts. Therefore,the solutions to reduce distortion under the premise of ensuring the expected performance of aluminum parts during quenching are clarified.
