为了适应引进及出口产品生产的需要,经过大量试验,我们研究成功了以NH_3、N_1、CO_2为介质的氮基气体软氮化新工艺,并应用于生产,取得了明显的技术和经济效益。 1.工艺试验 试验使用的设备是经过改造的18kW和35kW井式气体氮化炉。为控制氨气流量及通入炉内的压力,装有一台氨气控制箱,为测量氨分解率,安装 In order to meet the needs of the production of imported and exported products, after a large number of experiments, we successfully researched and succeeded in the new technology of nitrocarburizing nitrogen-based gas using NH 3, N 1 and CO 2 as mediums and applied them to the production. Obvious technical and economic benefits have been achieved. 1. Process test The equipment used for the test is a modified 18kW and 35kW pit gas nitriding furnace. In order to control the flow of ammonia gas and the pressure in the furnace, an ammonia control box is installed. To measure the ammonia decomposition rate, install
