感应器采用矩形紫铜管弯制焊接成型,并在其有效导体上装上导磁体,以改变电流走向来实现感应加热,这种感应器称为矩形感应器,它多用于平面和内孔的感应加热。近年来,一方面为了提高产品的使用寿命,对感应加热提出了新的要求;另一方面为了提高生产效率,用半圈旋转加热的矩形感应器代替外圆加热类型的感应器。我厂已应 The sensor is made of rectangular copper pipe bending and welding, and the effective conductor on the installed on the magnet, to change the current direction to achieve induction heating, this sensor is called a rectangular inductor, it is used for the plane and the hole in the induction heating. In recent years, on the one hand, in order to improve the service life of products, new requirements for induction heating have been put forward. On the other hand, in order to increase the production efficiency, a half-turn heating rectangular sensor instead of a cylindrical heating type sensor has been proposed. I plant should have
