四川省机械局于1979年11月15日至30日在双流县举办了一期“滴注式红外仪碳势自动控制技术短训班”。参加学习的除我省2价单位的49名学员外,还有来自全国其它十个省(市)22个单位的38名学员。CO_2红外仪滴注式可控气氛渗碳对稳定渗碳质量延长工件使用寿命,迅速改变我省热处理工艺的落后面貌有着重要意 The Sichuan Bureau of Machinery organized a short training course on automatic control of carbon potential of infusion infrared instruments in Shuangliu County from November 15th to 30th, 1979. Among the 49 students who participated in the study, including 2 units in our province, there were 38 students from 22 units in the other 10 provinces (cities). The CO_2 infrared instrument drip controlled atmosphere carburizing has important significance for stabilizing carburizing quality, prolonging the service life of the workpiece and rapidly changing the backward appearance of the heat treatment process in our province.
