局部淬火,特别是在汽车工业上的应用已成为减少能量消耗、减少淬火变形以及提高耐磨性的有效手段。感应加热用于各种类型金属工件的表面淬火已经有许多年了,有时候用于孔的内表面,有时候用于轴类的外表面等。这是一种众所周知,而且应用非常成功的技术。在所有这种感应加热操作中,工件里的感应电流都是形成闭合回路或称短路状态。感应加热操作可以“一次加热”方式对整个工件同时迅速加热,也可以使工件或感应圈的移动,
Partial hardening, especially in the automotive industry, has become an effective means of reducing energy consumption, reducing quench deformation and improving wear resistance. Induction heating has been used for surface hardening of various types of metal workpieces for many years, sometimes for the inner surfaces of holes, and sometimes for the outer surfaces of shafts. This is a well-known and very successful application of technology. In all such induction heating operations, the inductive current in the workpiece forms a closed loop or short circuit condition. Induction heating operation can “a heating ” way to the rapid heating of the entire workpiece at the same time, you can also make the workpiece or induction loop movement,
