摘要: This invention provides methods for rapidly heating a metal part of varying thickness. In general, the invention provides methods comprising heating the thicker section(s) of the part by induction heating and the thinner section(s) by resistance heating. Induction and resistance heating both quickly heat metals and because each is easily controlled individually, the part can be uniformly heated for hardening and tempering.
摘要翻译: 本发明提供了用于快速加热不同厚度的金属部件的方法。 通常,本发明提供的方法包括通过感应加热来加热部件的较厚部分,并且通过电阻加热来加热较薄的部分。 感应和电阻加热快速加热金属,并且由于每个都易于单独控制,所以该部件可以均匀加热以进行硬化和回火。
