如何确定感应加热炉感应线圈的匝数和铜管直径？

1. 感应器的直径

感应器的形状是根据加热零件的表面轮廓来确

定的，要求感应圈与零件之间必须有一定的间隙，

而且各处应均匀一致。

2. 对外圆加热时，感应器的内径 D 内 = D 0 +2a;

3. 对内孔加热时，感应器的外径 D 外 = D 0 －2a。其中，D 0

为工件的外圆直径或内孔直径，a 为二者之间的间隙

(对轴类零件取 1. 5 ～ 3. 5mm，齿轮零件取 1. 5 ～

4. 5mm，内孔零件取 1 ～2mm。

5. 如进行中频感应加热淬火，则间隙略有不同，一般轴类零件为 2. 5 ～3mm，内孔为 2 ～3mm)

How to determine the number of turns of the induction coil and the diameter of the copper tube of the induction heating furnace?

1. The diameter of the sensor

The shape of the inductor is determined according to the surface profile of the heating part

Certainly, there must be a certain gap between the induction coil and the parts,

And it should be uniform everywhere.

2. When heating the outer circle, the inner diameter of the sensor D inner = D 0 +2a;

3. When heating the inner hole, the outer diameter of the inductor D outside = D 0 －2a. Among them, D 0

Is the outer diameter or inner hole diameter of the workpiece, a is the gap between the two

(For shaft parts, take 1.5 ～ 3. 5mm, for gear parts take 1.5 ～

4.  5mm, the inner hole part is 1~2mm.

5.  For medium frequency induction heating and quenching, the gap is slightly different. Generally, the shaft parts are 2.5 ～3mm, and the inner hole is 2 ～3mm)
