摘　　要：以钢轨焊接接头焊后热处理作为研究对象,采用氧气-乙炔火焰加热进行钢轨焊后热处理,对比研究中频正火焊后热处理后钢轨温度。结果表明,采用中频正火焊后热处理可以得到钢轨温度更均匀。This essay investigates the rail welded splice heat treatment after being postweld. Compare the rail’s temperature after being postweld heat treated by oxygen - acetylene flame with medium-frequency normalization .The result shows the temperature of the rail after being heated by medium-frequency normalization was better balance than oxygen- acetylene flame .

关 键 词：焊后热处理 火焰加热 感应加热 中频电源
