读了航空学报第7卷第4期上刊登的樊东黎同志对“直接式炉气渗碳及其可控性”一文的看法(以下简称“看法”)后,对所提出的问题解释如下: 一、关于试验条件 空气加有机液体直接式炉气渗碳的研究是在25kW井式渗碳炉内进行的。炉温采用可控硅PID自动调节,波动不大于±5°C。每炉都装有渗碳面积约0.8m~2的低碳钢陪炉料。炉气组分用三台红外仪(CO、CO_2、CH_4)、氧探头(上海人民耐火材料厂及上海第二耐火材料厂产品)及色谱仪测定,用钢箔称重法测定炉气碳势。 After reading Fan Dongli’s article entitled “Direct Furnace Carburization and Its Controllability” published in Journal of Aeronautics, Vol. 7, No. 4 (hereinafter referred to as “View”), the issues raised were explained as follows: , The experimental conditions of air plus organic liquid direct furnace carburizing research is carried out in 25kW pit type carburizing furnace. The temperature of the furnace is controlled by thyristor PID automatically and the fluctuation is no more than ± 5 ° C. Each furnace is equipped with carburizing area of ​​about 0.8m ~ 2 with low carbon steel charge. Gas furnace components were measured by three infrared (CO, CO_2, CH_4), oxygen probes (Shanghai People’s Refractory Factory and Shanghai No.2 Refractory Factory) and chromatograph, and the carbon potential .
