卡博马格(Carbomaag)滴注式气体渗碳方法,是在50年代末和60年代初发展起来的。目前已在欧州和日本广泛应用。这种滴注法,基本上是依靠甲醇和丙酮或醋酸乙酯这一类渗碳剂来代替普通吸热式气氛。因此,在没有天然气供应或其价格很高的地区,用来代替普通的吸热式气氛渗碳。上述两种液体被同时而分别地导入炉内。甲醇裂解形成的气体先把炉内空气赶出,并在渗碳过程中为炉内提供正压力。丙酮或醋酸乙酯裂解形成的气体为炉内提供所需的碳势。采用卡博马格法而建造的多数炉子是井式炉和罐式炉。但是,这种工艺也可用于配备淬火油槽的卧式周期式炉和连续式炉。现在使用的最大滴注式渗碳炉的有效尺寸是直 Carbomaag drip gas carburizing was developed in the late 1950s and early 1960s. Has been widely used in Europe and Japan. This drip method, basically rely on methanol and acetone or ethyl acetate class carburizing agent to replace the general endothermic atmosphere. Therefore, there is no natural gas supply or its high price areas, instead of the general endothermic carburizing atmosphere. The two liquids are simultaneously and separately introduced into the furnace. The gas formed by the cracking of the methanol first drives the air out of the furnace and provides positive pressure to the furnace during the carburizing process. The gas formed by the cracking of acetone or ethyl acetate provides the desired carbon potential in the furnace. Most of the furnaces built using the Kap Bomag method are pit and pot furnaces. However, this process is also available for horizontal and continuous furnaces with quench tanks. The effective size of the largest drop-on carburizing furnace now used is straight
