我厂要淬火一批内径只有5毫米的小滚轮。为此,经几次研究,参考有关资料,按电磁感应的原理制造了一种围环式的感应器(如图示)。感应器的围环之所以加大,是为了使磁场减弱,防止加热过程中对工件侧面的影响。经使用,效果很好,处理的工件基本上符合图纸要求。 I plant to quench a number of small wheels diameter of only 5 mm. To this end, after several studies, refer to the relevant information, according to the principle of electromagnetic induction to create a ring-type sensor (as shown). The reason why the inductor ring increases, is to make the magnetic field weakened to prevent the heating process on the side of the impact. After use, the effect is very good, the processing of the workpiece basically meets the drawing requirements.
