西德爱协林公司今年在北京举办的西德工业展览会上介绍了一种新的气体软氮化方法。该方法的特点是用普通放热式气和氨通入井式炉或半连续箱式炉在570℃的温度下进行处理。该工艺的商用名称为NITROC,是爱协林公司的专刊。在半连续式炉中进行软氮化处理时,零件先在放热式气氛保护下施行300℃的预热,然后再在通入30%NH_3和70%放热式气的加热室中氮化2～3小时,最后在放热式气的保护
West Germany Love Forest Company held in Beijing this year, West Germany Industrial Exhibition introduced a new gas nitrocarburizing method. The method is characterized by the use of normal exothermic gas and ammonia into the pit furnace or semi-continuous box furnace at a temperature of 570 ° C for processing. The trade name for this process is NITROC, a companion to Aixin Lin. In a nitrocarburizing process in a semi-continuous furnace, the parts were preheated at 300 ° C under the protection of an exothermic atmosphere and then nitrided in a heating chamber which was charged with 30% NH 3 and 70% exothermic gas 2 to 3 hours, the last in the exothermic gas protection
