Principle of medium frequency induction heating in steel billet heating equipment

Technical background:

Intermediate frequency induction heating is a widely used heating method in steel billet induction heating furnace, based on the basic theory of electromagnetic induction. Through the action of electromagnetic fields, current generates thermal energy on the surface of steel billets, thereby raising their temperature. The medium frequency induction heating equipment of Forever Electromechanical adopts this principle and is applied in industries such as steel metallurgy and mechanical processing.

Principle of medium frequency induction heating:

1. Principle of electromagnetic induction:

Intermediate frequency induction heating relies on the electromagnetic induction effect generated by high-frequency current in metallic materials. An alternating magnetic field is formed around the electrified conductor (heating coil), which induces current (eddy current) in the steel billet. Eddy currents are converted into heat through the resistance of metals, thereby achieving heating.

2. Thermal energy conduction:

During the process of medium frequency induction heating, eddy currents mainly concentrate on the surface of the steel billet. Due to the resistance effect of the steel, the temperature of the surface layer will gradually increase. As the heating continues, the heat gradually conducts into the interior of the steel billet, achieving uniform overall heating.

3. Relationship between heating depth and frequency:

The frequency of medium frequency steel billet induction heating equipment is usually between 1 kHz and 100 kHz. The higher the frequency, the more concentrated the eddy current is on the metal surface, and the heating depth is shallower; When the frequency is low, eddy currents can penetrate deeper and are suitable for heating larger volume steel billets.

Forever Electromechanical's medium frequency induction heating technology, based on the principle of electromagnetic induction, can achieve uniform heating of steel billets by accurately controlling the frequency and current intensity. The application of this technology ensures the stability of steel in subsequent processing and improves production efficiency.
