一、矩形感应器加热的主要优点汽车的传动、转向、悬挂系统的多种轴类零件,承受较高的弯曲和扭转疲劳载荷。这些零件以前多用中碳低合金钢制造,并经调质处理。与中频热处理相比,调质的主要缺点是零件寿命低,材料费和电能消耗多,成本高。许多零件如传动轴、前中后桥半轴、转向节、平衡轴和摆臂轴等已采用中频感应加热淬火。这些零件多是变截面轴,淬 First, the main advantages of rectangular inductor heating Automotive transmission, steering, suspension system of a variety of shaft parts, to withstand high bending and torsion fatigue load. These parts were previously made of low carbon medium carbon steel, and quenched and tempered. Compared with the IF heat treatment, the main drawback of quenching and tempering parts life is low, the material cost and energy consumption, high cost. Many parts such as the drive shaft, the front axle in the rear axle, the steering knuckle, the balance shaft and the swing arm shaft have been induction quenched with IF induction heating. These parts are mostly variable cross-section axis, quenching
