滴入式控制气氛渗碳及碳氮共渗是近年来日益发展的一项新工艺。它的优点是工艺易掌握、原料来源广、设备简单,普通井式气体渗碳炉稍加改装即可应用,投资小,上马快,便于工厂的技术改造。尤其对中、小厂和多品种小批量生产的热处理车间是提高产品质量的有效途径。遵照伟大领袖和导师毛主席关于“独 Instill control atmosphere carburizing and carbonitriding is a new technology developed increasingly in recent years. Its advantage is easy to grasp the process, wide source of raw materials, simple equipment, general well gas carburizing furnace can be applied a little modification, small investment, quick start, easy factory technical transformation. Especially for medium and small factories and small variety of small batch production of heat treatment workshop is an effective way to improve product quality.
