　　 Energy-saving medium-frequency induction furnace Most applications involve continuous induction heating of regular round bars, square bars, or other shaped billets made of steel (diameter ≥ Φ18), stainless steel, copper, aluminum, and similar materials. This process is primarily used for the continuous, uniform heating of the entire workpiece. Below, we’ll introduce the advantages of medium-frequency induction furnaces in bar stock processing.

　　1. Wide frequency range, from 1 kHz to 20 kHz; the appropriate frequency can be selected based on the diameter of the workpiece being heated.

　　2. When heating solid materials in an energy-saving medium-frequency induction furnace, the induction coil should be 500 mm to 1.2 meters long, and multiple pieces of material can be heated simultaneously, further ensuring thorough heat penetration.

　　3. The energy-saving medium-frequency induction furnace adopts a continuous heating method, ensuring a relatively balanced load within the induction coil. This approach overcomes the significant fluctuations in equipment’s actual heating power that typically occur during the entire heating process—specifically, when a single bar is heated from room temperature to 1100℃, causing a dramatic change in load. As a result, throughout the entire continuous heating process, the equipment’s actual power output can consistently remain above 85% of its rated power, enabling efficient utilization of the equipment.

　　4. When heating non-ferrous metals such as copper and aluminum, by reasonably designing the induction coil and capacitors, the actual power utilization of energy-saving medium-frequency induction furnaces can reach over 85% of their rated power. When heating copper, the furnace can achieve a heating capacity of 3.5 kg/kW·hour.

　　5. Compared to thyristors Energy-saving medium-frequency induction furnace Not only is it compact in size and easy to maintain, but it can also save 15–20% on electricity.
