火焰表面淬火法是不用加热炉进行热处理的一种淬火方法。它具有设备简单、操作灵活、不受工件形状限制、不氧化脱碳以及变形小的特点。对于没有高、中、工频的单位或工件不能采用感应加热的工厂很适宜。目前,国外一些工业发达国家利用火焰淬火的特色成功地应用在大型齿轮、大型工作平面、轧辊、各种凸轮、曲轴、机床导轨、链轮上。我厂曾用火焰淬火为冶金、矿山、纺织、交通运输、化工、通用机械行业处理过上千种工件,取得了很好的效果。
Flame surface quenching method is not a heat treatment furnace for a quenching method. It has the characteristics of simple equipment, flexible operation, not limited by the shape of the workpiece, non-oxidative decarburization and small deformation. For no high, medium and power units or workpieces can not be used induction heating factory is appropriate. At present, some developed countries in foreign countries use the characteristics of flame hardening successfully applied to large gears, large work planes, rollers, various cams, crankshafts, machine guide rails and sprockets. Our factory has used flame quenching for metallurgy, mining, textiles, transportation, chemicals, general machinery industry handled thousands of workpieces, and achieved good results.
