本文简述了氧探头在我厂应用时所经历的三个阶段，即从35千瓦井式气体渗碳炉工艺试验到WC25B滴注式可控气氛连续生产线（简称贯通炉）生产过程测试，积累了大量有价值的数据，为第三阶段正式应用到生产之中打下了坚实的基础，积累了宝贵的经验。本文着重介绍了氧探头在CZDK87贯通炉上的应用情况经历的过程、取得的成效以及今后的打算 This article briefly describes the oxygen probe in the application of the three stages of my experience, that is, from 35 kilowatts pit gas carburizing furnace process test to WC25B drip controllable atmosphere continuous production line (referred to as through the furnace) production process testing, accumulation A lot of valuable data for the third phase of formal application into production has laid a solid foundation and accumulated valuable experience. This article focuses on the oxygen probe in the CZDK87 through the furnace on the application of the experience of the process, the results achieved and future plans
