The working principle of the steel bar heating furnace is mainly based on electromagnetic induction technology, which is used to heat steel bars quickly and evenly. It is widely used in processes such as forging, rolling and heat treatment.

1. Electromagnetic induction heating

- Basic principle: The steel bar heating furnace passes high-frequency or medium-frequency alternating current through the induction coil to generate an alternating magnetic field. When the steel bar is placed in the induction coil, the magnetic field induces eddy currents inside the steel bar.

- Eddy current heating: Eddy currents flow inside the steel bar. Due to the resistance of the steel bar, the eddy current energy is converted into heat, which causes the steel bar to heat up quickly.

2. Heating process

- Rapid heating: Electromagnetic induction technology allows the steel bar to heat up in a short time to reach the required processing temperature.

- Uniform heating: By controlling the design of the induction coil and the current frequency, the overall heating of the steel bar is ensured to be uniform and heat treatment defects are reduced.

3. Temperature control

- Accurate control: Modern steel bar heating furnaces are equipped with intelligent control systems that can accurately adjust and control the temperature to ensure that the heating process meets the process requirements.

The steel bar heating furnace uses electromagnetic induction technology and eddy current effect to quickly heat the steel bar. It has the characteristics of fast heating, uniform heating and precise temperature control. It is an indispensable equipment in metal processing.
