现在我国机床制造厂中,感应加热已经广泛用于钢制零件(齿轮,轴等)的表面淬火,以提高机床零件的强度和耐磨性。但铸铁的高频淬火还没有得到应用。 国外对铸铁采用高频淬火的问题已游行了不少研究工作,说明很多铸铁机器零件采用高频淬火具有很大的优越性,在机床制造厂中,床身导轨 Now in China’s machine tool factory, induction heating has been widely used in the surface hardening of steel parts (gears, shafts, etc.) to improve the strength and wear resistance of machine tool parts. However, the high frequency quenching of cast iron has not been applied. Abroad on the use of high-frequency quenching of cast iron has been paraded a lot of research work shows that many cast iron machine parts using high-frequency quenching has great advantages in the machine tool factory, bed rails
