How to choose the sensor of the induction furnace?

A. Types of sensors for induction furnaces

The inductors of the induction furnace include through-type inductors, end heating inductors, local heating inductors, steel plate heating inductors, oval inductors, flat coil inductors, long bar continuous heating inductors, and steel bar heating inductors. , Aluminum rod heating sensor, copper rod heating sensor, steel tube heating sensor, cylinder heating sensor and so on. Due to the different shapes of the parts, there are many kinds of inductors in the induction furnace, and the shapes and types of the inductors are also various, and they are generally customized according to different heating types.

B. The sensor composition of the induction furnace

The inductor of the induction furnace is composed of induction coil, copper water nozzle, copper screw, bakelite column, bottom bracket, cement asbestos support plate, furnace mouth plate, connecting copper bar, confluence copper bar, water-cooled guide rail, coil insulation and furnace lining material, etc. .

C. Inductor components of the induction furnace

1. The inductor coil of the induction furnace is also called the furnace head of the intermediate frequency furnace. It is made of rectangular copper tube. After the induction coil is energized, an alternating magnetic field is generated, which causes eddy currents on the surface of the parts to heat the parts. The induction (coil) coil is the core part of the inductor.

2. The inductor busbar of the induction furnace is mainly used for the input current of the inductor coil of the intermediate frequency induction furnace.

3. The main purpose of the water-cooled guide rail is to protect the furnace lining material and avoid damage to the furnace lining due to frictional contact between the metal workpiece and the furnace lining material. Induction furnace’s sensor

4. The purpose of bakelite column and copper screw is to fix the induction coil and keep the distance between turns unchanged.
