高频氮化的主要优点是速度快,生产周期短。沉淀硬化不锈钢的高频氮化效果尤其显著,可比一般辐射加热炉氮化时间缩短90%。这是因为在高频电磁场的作用下可加速氨的分解,促使在氮化零件表面形成大量氮原子,并不断更新。1.氮化装置高频感应加热气体氮化采用 GP-60型高频发生器。在加热变压器上接多圈感应器作为加热源。氮化瓶是用石英玻璃或 GG17耐高温玻璃制成,氨气由液氨瓶直接供给。为便于操作,测温控制仪、分解瓶、流量计、
The main advantage of high-frequency nitriding is speed, short production cycle. The high frequency nitriding effect of precipitation hardened stainless steel is especially remarkable, which can be reduced by 90% compared with that of the general radiant heating furnace. This is because the role of high-frequency electromagnetic fields can accelerate the decomposition of ammonia, prompting the formation of nitrogen parts in the surface of a large number of nitrogen atoms, and constantly updated. 1. Nitride device high-frequency induction heating gas nitrided GP-60 type high-frequency generator. In the heating transformer connected multiturn sensors as a heating source. Nitriding bottle is made of quartz glass or GG17 high-temperature glass, ammonia from liquid ammonia bottle directly supply. For ease of operation, temperature controller, decomposition bottle, flow meter,
