半轴法兰圆角大直径范围的感应淬火

坡道载荷设计法要求半轴法兰圆角大直径范围和杆部深层硬化 ,以充分发挥材料的潜力 ,实现强度与塑性的合理配合。介绍了满足半轴法兰圆角大直径范围淬火感应器的设计、感应淬火工艺参数以及半轴的性能。结果表明 ,带锥角镶嵌导磁体的圈式感应器 ,其有效圈高度、锥角和内径的合理匹配可以满足淬硬层形态的要求 ,采用立式淬火机床连续淬火可以大批量生产合格的半轴。

Induction Quenching of Partial Flange with Great Diameter

In order to bring the material function into play the ramp load method demands the flange rigidification with great range and deep layer. The paper describes quenching technique about this flange and its character. The result shows that the quenching inductor with wimble magnet inlaid is adaptable for this technique, and the vertical quenching machine can be used in mass production.
