Description
The continuous casting and rolling billet heating furnace is a high-efficiency induction heating solution for billets immediately after casting, enabling continuous casting to rolling integration.
Also known as continuous casting and rolling billet induction heating equipment or billet temperature maintenance and preheating system, it ensures uniform billet temperature, minimizes oxidation, and optimizes energy consumption.
This billet heating furnace for continuous casting and rolling is widely applied in modern steel mills pursuing high productivity and energy efficiency.
🔹 Challenges in Continuous Casting & Rolling
In traditional rolling mills, billets often experience:
* ❌Significant heat loss after casting
* ❌Uneven billet temperature in the rolling mill
* ❌Surface oxidation or decarbonization
* ❌Energy inefficiency
The billet continuous casting and rolling preheating equipment addresses these challenges by:
* Heating billets directly after casting
* Ensuring uniform temperature along the billet length
* Reducing energy consumption and oxidation losses
🔹 Continuous Casting & Rolling Billet Heating Furnace Solution
The continuous casting-rolling billet heating furnace uses medium-frequency electromagnetic induction to raise the billet temperature rapidly:
* Supports direct integration with rolling lines
* Automatically adjusts power based on billet temperature and speed
* Reduces billet surface oxidation compared with traditional flame furnaces
* Ensures stable and uniform heating for high-quality rolling
Yuantuo continuous casting-rolling billet induction heating equipment is ideal for square billets, supporting a fully automated preheating and feeding process.
🔹 Advantages of Continuous Casting & Rolling Billet Heating Equipment
✅ High energy efficiency: 40–110 kWh per ton, depending on billet temperature
✅ Reduced surface oxidation: scale ≤0.5%
✅ Uniform temperature: eddy current heating ensures consistent heating inside billets
✅ Fast heating response: supports high-speed rolling lines
✅ Automated temperature control: PLC + infrared sensors ensure precise preheating
✅ Flexible billet dimensions: 60–200 mm square, length 3–12 m
This billet heating furnace for continuous casting and rolling guarantees both high productivity and high-quality billets.
🔹Working Principle
The continuous casting and rolling billet heating furnace converts three-phase AC power into medium-frequency current, which flows through the induction coil:
1. High-density magnetic field induces eddy currents inside the billet
2. Billet self-heats rapidly and uniformly
3. PLC-controlled system adjusts power to maintain constant outlet temperature
Compared with separate billet preheating and secondary reheating, the continuous casting-rolling billet heating furnace reduces energy loss and improves production efficiency.
