摘要
渗碳零件质量的好坏取决于表面的碳浓度和渗碳深度,而零件表面碳浓度又取决于炉气碳势。分析了零件气体渗碳处理中的炉气碳势测量原理,提出用测氧传感器测量碳势及碳势的自动化控制方法。
The quality of curburizing works depends on its surface carbon density and the degree of carburizing while carbon density de- pends on carbon tendency of stove gas,this article analyzes the measurement principle of stove gas carbon tendency when gas carburizing being handled,proposes using oxygen sensor to measure carbon tendency and its automatic control.
