摘要: 分别采用同时加热淬火方式和连续加热淬火方式对45钢锻件车轮进行感应淬火研究。结果表明:采用连续加热淬火方式(感应器与工件间隙6 mm、输出功率为339 kW、频率为6.3 kHz),用清水进行喷淋冷却,然后对其进行230 ℃×2 h炉中回火处理后,车轮外表面踏面及倒圆角区域的表面硬度为509~599 HV0.2(50~55 HRC)、淬硬层深度为3.4~4.7 mm、显微组织级别为5~7 级,均能达到其技术要求,并在工业化试生产中取得了较好的应用效果。

Abstract: Induction heating and quenching process for 45 steel forging wheel was studied by simultaneous heating mode and continuous heating mode, respectively. The results show that when using continuous heating (the gap between the inductor and the workpiece is 6 mm, the output power is 339 kW, and the frequency is 6.3 kHz) with spray water cooling, and then tempered at 230 ℃ for 2 h in a heat treatment furnace, the surface hardness of the wheel outer surface tread and fillet area is 509-599 HV0.2 (50-55 HRC), the depth of the hardened layer is 3.4-4.7 mm, and the microstructure grade is 5-7, which can all meet the technical requirements of the wheel, and acquires good results in industrial pilot production.
