当采用氨滴乙醉进行气体软氮化时,炉内发生如下反应:2NH_3→2〔C〕+3H_2O,C_2H_5OH→〔C〕+3H_2+CO。和普通氮化一样,炉气的氮势决定于未分解氮和氢的含量。若知道了未分解氨的含量,可为调节氨的流量和乙醇滴入量提供一定的依据,知道了氨分解率则就知未分解氨,因此,氨分解率是气体软氮化中的一个重要工艺参数。在设备较齐全的工厂,一般都配有氨分解率测定仪,但该仪器是玻璃的,易损坏,而且有些地区市面上还难以买到。为了满足生产需要,我们利用疏
When the use of ammonia dripping B drunk gas nitrocarburizing, the furnace reaction occurs as follows: 2NH_3 → 2 [C] + 3H_2O, C_2H_5OH → [C] + 3H_2 + CO. As with normal nitriding, the nitrogen potential of the furnace gas depends on the content of undecomposed nitrogen and hydrogen. Knowing the content of undecomposed ammonia can provide a basis for adjusting the flow rate of ammonia and the amount of ethanol dropped in. Knowing the ammonia decomposition rate, it is known that ammonia is not decomposed, therefore, the ammonia decomposition rate is one of the gas nitrocarburizing Important process parameters. In more well-equipped plants, ammonia decomposition rate meters are generally available but the glass is easily damaged and in some areas it is hard to find. In order to meet production needs, we use sparse
