滴注式可控气氛渗碳工艺与用气体发生炉的可控气氛渗碳工艺比较,不需要专门而复杂的设备,对井式气体渗碳炉稍加改造即可使用,因而有利于老厂采用该项新工艺。滴注式可控气氛渗碳炉采用红外线碳势自动控制仪测定炉气中 CO_2的浓度.能迅速和正确地控制炉内的碳势,解决了过去难于控制碳势而造成零件过碳和贫碳现象,提高了产品的质量。我们在北京分析仪器厂和南口机车车辆机械工厂的协助下,制成了 KH-02型比例脉冲调节器和简易色谱仪,并制造了一台适合于可
Drip-controlled atmosphere carburizing process with the gas furnace controllable atmosphere carburizing process does not require specialized and complex equipment, the gas well carburizing furnace can be slightly modified to use, which is conducive to the old plant Using the new technology. The drip-controlled atmosphere carburizing furnace adopts the infrared carbon potential automatic controller to measure the concentration of CO 2 in the furnace gas, which can quickly and accurately control the carbon potential in the furnace and solve the problems of over carbon and poor parts control in the past Carbon phenomenon, improve product quality. With the help of Beijing Analytical Instrument Factory and Nankou Locomotive and Rolling Stock Factory, we made KH-02 proportional pulse conditioner and simple chromatograph, and made a suitable for
