普通阀门阀杆,一般用中碳结构钢(如35号钢)制作,并经抗蚀氮化后使用。未经抗蚀氮化处理的阀杆锈蚀迅速,很快与阀体部分咬死而致使阀门无法使用。阀门行业规定,未经抗蚀氮化处理的阀门,不得列为正品,所以抗蚀氮化是阀门生产中的重要工序之一。目前阀门行业多数工厂都用硬氮化处理。我们根据贵阳阀门厂只有气体渗碳炉的现有条件,采用了气体软氮化代替传统的抗蚀氮化,经三年来应用证明,气体软氮化不仅可行,而且还具有较
Ordinary valve stem, the general use of carbon structural steel (such as 35 steel) production, and after nitriding corrosion use. Without corrosion nitriding stem rust quickly, and the body part of the body quickly killed and the valve can not be used. Valve industry regulations, without anti-corrosion nitriding valve may not be classified as genuine, so nitrided corrosion is one of the important processes in the production of valves. At present, most factories in the valve industry are hard nitriding. According to GuiYang valve factory only gas carburizing furnace existing conditions, the use of gas nitrocarburizing instead of the traditional anti-corrosion nitriding, after three years of application shows that gas nitrocarburizing is not only feasible, but also has more
