石棉绳在热处理中有很多用处,但在高频感应加热中的应用报道较少。我们根据多年的生产经验,证明石棉绳在高频加热中,对控制感应器与工件之间的间隙,增强细铜管绕制的大直径感应器的刚性,提高感应加热效率,防击穿故障等,有很大的实用价值。现介绍如下: 1.用石棉绳控制感应器与被加热工件间的间隙在实际生产中,常有一些工件的小直径内孔(≤30mm),盲孔底部,窄槽侧面或底面,圈的内斜面等部位形状特殊,空间不 Asbestos rope in heat treatment has many uses, but the application of high frequency induction heating is reported less. Based on many years of production experience, we prove that asbestos rope in the high-frequency heating, the control of the gap between the sensor and the workpiece to enhance the thin copper tube wound diameter of large-diameter sensors to improve the induction heating efficiency, anti-wear failure Etc., have great practical value. Now introduced as follows: 1. With asbestos rope control the gap between the sensor and the heated workpiece In the actual production, there are often some small diameter bore (≤ 30mm), the bottom of the blind hole, the narrow side or bottom of the groove, the ring Slope and other parts of a special shape, space is not
