该厂自行设计制造的渗碳炉由供气系统、发生炉系统、工作炉和控制系统四部分组成。工作炉采用低电压大电流、无马弗方式加热,通以丙烷为原料的吸热式可控气氛,借助红外线分析仪,实行可控气体渗碳。这种方法渗碳,速度快、效率高,与滴苯渗碳相比较,渗碳深度同为4.2毫米,滴苯渗碳需要110～120小时,而可控气氛只需要60小时。文中列有渗碳炉的技术规格,并以1077992型轴承外圈和滚子为例进行试验和分析。附图9幅,表5个。
The factory design and manufacture of carburizing furnace from the gas supply system, furnace system, furnace and control system of four parts. The working furnace adopts low voltage and high current, without heating in the way of the muffle, through the endothermic controlled atmosphere with propane as the raw material, with the aid of the infrared analyzer, the controllable gas carburizing is implemented. This method carburizing, fast, high efficiency, compared with carburizing benzene, carburizing depth of 4.2 mm, carburizing benzene need 110 to 120 hours, while the controlled atmosphere takes only 60 hours. The article lists the technical specifications carburizing furnace, and 1077992 bearing outer ring and roller as an example for testing and analysis. Figure 9 Figure, Table 5.
