【摘要】 本文简述了煤油+空气增压渗碳工艺的基本原理，并对增压渗碳工艺进行了研究，实验结果证明，当采用煤油添加空气直升式渗碳气氛，炉内压力由20～30mm增加到150～200mm水柱，渗碳速度增加一倍。更多还原

【Abstract】 This paper describes the basic principle of coal oil plus air pressure carburizing and studies the pressure carburizing technique. Experimental results show that when the inside pressure of furnace increases from 20~30mm to 150~200mm H2O,carburizing speed is doubled.更多还原
