Description
The square billet heating furnace is a specialized induction heating solution designed for square billets .
Also known as a square billet induction heating furnace, square billet electric induction heating furnace, or square billet heating equipment, it ensures uniform temperature, precise control, and minimal surface oxidation.
Hebei Yuantuo Electromechanical offers this solution with reliable performance, helping steel mills achieve high-quality, energy-efficient billet heating.
🔹Challenges in Square Billet Heating
Steel mills often face:
* ❌Uneven temperature distribution in square billets
* ❌Surface oxidation and scale formation during conventional heating
* ❌High energy consumption with fuel-fired furnaces
* ❌Difficulty integrating preheating with rolling lines
The square billet induction heating furnace addresses these issues with rapid, uniform heating, reduced oxidation, and automated temperature control.
🔹 Square Billet Induction Heating Furnace Solution
This uses medium-frequency electromagnetic induction:
* Converts three-phase AC into medium-frequency current
* Induces eddy currents in the square billet, heating it evenly from surface to core
* PLC-controlled system with infrared temperature sensors ensures precise temperature maintenance
* Reduces heating time compared with traditional flame furnaces
* Compatible with square billet heating production lines
The solution improves billet quality, reduces energy consumption, and supports high-speed rolling lines.
🔹 Advantages
✅ Rapid heating: significantly shorter preheating time
✅ Uniform temperature: eddy current heating ensures consistent billet temperature
✅ Energy-efficient: 40–110 kWh per ton depending on billet surface temperature
✅ Low oxidation: surface scale ≤0.5%
✅ Automated control: PLC + infrared sensors for closed-loop temperature control
✅ Flexible billet size: supports square billets 60–200 mm, length 3–12 m
This square billet electric induction heating furnace ensures high-quality billets ready for rolling.
🔹 Working Principle
1. Square billets enter the induction coil system from the casting or storage area
2. Medium-frequency current in the induction coil generates a magnetic field
3. Eddy currents induce internal heating in the billets
4. Infrared sensors and PLC control adjust power automatically to maintain constant outlet temperature
5. Heated billets are discharged to the rolling line with minimal surface oxidation
Compared with conventional fuel-fired square billet heating furnaces, this induction solution is faster, cleaner, and more energy-efficient.
