摘　　要：通过台式陶瓷纤维高温电阻炉模拟加热的方法对不同加热制度下弹簧钢60Si2MnA表面脱碳情况进行了研究,就加热温度和保温时间对其脱碳层深度的影响进行了分析。通过试验模拟加热炉内气氛的方法研究了O_(2)、CO_(2)含量对弹簧60Si2MnA表面脱碳的影响。得出结论:在相同的试验条件下,随着CO_(2)及O_(2)量的升高,完全脱碳层的深度在增加。Through the simulation method of heating furnace box,we studied the effects of different heating systems on surface decarburization of the spring steel 60Si2MnA,and analyzed the effects of heating temperature and holding time on the depth of surface decarburization.Through the experimental simulation method of heating atmosphere,we studied the influence of O_(2),CO_(2)content on surface decarburization of 60Si2MnA.We found that the depth of complete decarburization layer is deepening with the increasing amount of CO_(2)and O_(2)in the same test conditions.
