目前螺丝刀头的淬火大多是采用盐浴炉来加热 ,其缺点是加热效率低 ,仅预热就达 2ｈ之久 ,劳动强度大。有的单位采用了高频淬火 ,但由于工件采用逐个手动加热 ,生产效率不高。通过对高频设备的改装和调试 ,在螺丝刀自动淬火线上成功应用。我厂对 60ｋＷ高频设备感应器进行了改造 At present, most of the screwdriver head quenching salt bath furnace to heat, the disadvantage is the heating efficiency is low, only up to 2h preheating, labor-intensive. Some units using high-frequency quenching, but because the workpiece by manual heating one by one, the production efficiency is not high. Through the high-frequency equipment modification and commissioning, the successful application of automatic screwdriver quenching. I plant 60kW high-frequency equipment sensors were transformed
