底喷式淬火装置

Bottom Spray Quenching Device

在众多改善金属材料性能的热处理工艺中,淬火无疑是最常用的一种热处理工艺,但是对于大直径的套筒类零件来说,其工作表面是内表面,而内表面往往由于在淬火过程中温度不能迅速降低,导致内表面强度和硬度不高而降低其使用寿命,文中阐述了一种底喷式淬火装置,通过该装置处理的油缸缸筒的性能满足了零件的工艺要求,延长了油缸的使用寿命。

Among the improvement of the heat treatment of metal materials, quenching is one of the most common heat treatment processes. But for the large diameter thin-walled sleeve parts, the low service life and low strength and hardness of its inner surface is often generated due to low reduction speed of the temperature in the quenching process. This paper expounds a new-type bottom spray quenching device, which can make oil cylinder meet the technological requirement, and can prolong the service life of the oil cylinder.
