Description
The continuous casting billet heating furnace is designed for modern steel mills to efficiently preheat and equalize temperature in continuous casting billets .
Also referred to as continuous casting billet induction heating furnace, continuous casting billet heating equipment, or continuous casting billet reheating furnace, this solution ensures uniform temperature, precise control, and reduced surface oxidation.
Hebei Yuantuo Electromechanical provides reliable continuous casting billet heating solutions that integrate seamlessly with rolling mills for high-quality, energy-efficient steel production.
🔹 Challenges in Continuous Casting Billet Heating
Steel plants often face these challenges:
* ❌Temperature differences between billet surface and core
* ❌Surface oxidation and scale formation with traditional fuel-fired furnaces
* ❌Energy inefficiency and long heating cycles
* ❌Difficulties in maintaining consistent billet quality before rolling
The continuous casting billet heating furnace addresses these issues by providing rapid heating, uniform temperature, automated control, and minimal oxidation.
🔹 Continuous Casting Billet Heating Furnace Solution
The uses medium-frequency electromagnetic induction:
* Converts three-phase AC into medium-frequency current
* Generates eddy currents inside billets for uniform internal and surface heating
* PLC-controlled system with infrared temperature measurement maintains stable exit temperature
* Significantly reduces heating time compared with conventional flame furnaces
* Compatible with continuous casting billet heating equipment and hot rolling lines
This technology improves billet quality, reduces energy consumption, and supports high-speed rolling operations.
🔹 Advantages
✅ Rapid and uniform heating: minimizes temperature gradients between surface and core
✅ Energy-efficient: 38–110 kWh per ton depending on billet surface temperature
✅ Reduced oxidation: surface scale ≤0.5%
✅ Automated control: PLC + infrared sensors for closed-loop temperature control
✅ Flexible billet sizes: supports square and rectangular billets, lengths 3–12 m
✅ Low maintenance: fewer mechanical parts than conventional furnaces
With Hebei Yuantuo Electromechanical solutions, billets are heated efficiently and safely before entering the rolling process.
🔹 Working Principle
1. Continuous casting billets enter the induction coil system from the casting machine or storage area
2. Medium-frequency current in the induction coil produces a magnetic field
3. Eddy currents in the billet induce internal heating
4. Infrared sensors and PLC control adjust power automatically for precise exit temperature
5. Heated billets are discharged to rolling lines with minimal surface oxidation
Compared with traditional continuous casting billet fuel-fired heating furnaces, the Yuantuo induction furnace is faster, cleaner, and energy-efficient.
