Description

一种离子渗氮炉的装料筒
技术领域
本发明涉及一种离子渗氮炉的装料筒。
背景技术
离子渗氮炉的工作过程为：先将工件放入炉内作为阴极，炉体作为阳极，再通入少量氨、氮或氮氩混合气体，然后在两极间施加一定电压使氮电离，氮电离后即以髙速冲击工件，离子的动能转化为热能将工件加热至渗氮温度。轰击表面的一部分氮夺取电子后直接渗入工件表面，在工件表面上形成含氮极高的呈蒸发状态的Fe，并不断向工件内部扩散，从而达到渗氮的目的。
发明内容
本发明通过改进进气管的布局，使氮化更均匀。
本发明提供了一种离子渗氮炉的装料筒，所述装料筒包括筒体、筒盖、进气管Ⅰ、进气管Ⅱ，所述筒盖固定在筒体上，筒壁上设有进气管Ⅰ与进气管Ⅱ，使筒体内气流旋转，所述筒底上设有若干个排气孔。
本发明所述进气管Ⅰ优选为位于筒壁的上部且水平向筒体的轴方向出气，所述进气管Ⅱ优选为位于进气管Ⅰ正下方的筒壁下部且竖直向上出气。
本发明所述进气管Ⅰ直径与筒体直径的比例优选为1：20-30。
本发明所述进气管Ⅱ直径与筒体直径的比例优选为1：20-30。
本发明有益效果为：
本发明所述离子渗氮炉的装料筒内能形成旋转的气流，使氮化更加均匀，氮化效果更佳。
附图说明
本发明附图1幅，
图1为实施例1所述离子渗氮炉的装料筒结构简图；
其中，1、筒体，11、排气孔，2、筒盖，3、进气管Ⅰ，4、进气管Ⅱ。
具体实施方式
下述非限制性实施例可以使本领域的普通技术人员更全面地理解本发明，但不以任何方式限制本发明。
实施例1
一种离子渗氮炉的装料筒，所述装料筒包括筒体1、筒盖2、进气管Ⅰ3、进气管Ⅱ4，所述进气管Ⅰ3直径、进气管Ⅱ4直径与筒体1直径的比例为1：1：25，所述筒盖2固定在筒体1上，所述进气管Ⅰ3位于筒壁的上部且水平向筒体1的轴方向出气，所述进气管Ⅱ4位于进气管Ⅰ3正下方的筒壁下部且竖直向上出气，使筒体1内气流旋转，所述筒底上设有若干个排气孔11。
