空气(或氧)加氨氮化(以下简称氮化)是近年来发展起来的新工艺,由于氮化效果显著、无公害、气源广、设备简单、操作方便,因而在国内得到了广泛地应用。我厂在研究球铁氮化的基础上,应用在热锻模上,取得了较满意的效果。一、工艺流程及简单原理使用改装的Ц-35气体渗碳炉,风扇轴密封为水冷油封式,气密性好,流程如图1。氮化剂是空气加氨气,氨减压至1公斤/厘米~2进入KOH干燥罐,压缩
Air (or oxygen) plus ammonia nitriding (hereinafter referred to as nitriding) is a new technology developed in recent years, due to significant nitriding effect, pollution-free, wide source of gas, simple equipment, easy operation, which has been widely used in China . I plant in the study of iron nitride, based on the application in the hot forging die, and achieved more satisfactory results. First, the process and simple The use of modified Ц-35 gas carburizing furnace, the fan shaft seal is water-cooled oil seal, air tightness, the process shown in Figure 1. Nitriding agent is air plus ammonia, ammonia decompression to 1 kg / cm ~ 2 into the KOH drying tank, compressed
