Description
The billet heating production line is a fully integrated solution for heating, temperature maintenance, and feeding of steel billets before rolling.
Also called a billet induction heating production line, billet preheating and temperature maintenance production line, or continuous casting billet heating production line, it ensures uniform temperature, reduced oxidation, and optimized energy efficiency across the entire billet processing workflow.
Ideal for modern steel mills, the billet heating production line integrates induction heating furnaces, conveyor systems, temperature control, and automation, supporting high-volume, high-quality billet production.
🔹Challenges in Billet Heating Production
Steel mills often face:
* ❌Heat loss after continuous casting
* ❌Uneven billet temperature entering the rolling line
* ❌Surface oxidation or decarbonization during waiting or transport
* ❌Energy inefficiency and high operational costs
The billet heating production line addresses these challenges by combining induction heating, automatic temperature control, and continuous feeding, ensuring stable and high-quality billets for rolling operations.
🔹Billet Heating Production Line Solution
The billet induction heating production line uses medium-frequency electromagnetic induction for rapid and uniform heating:
✅Automatic temperature adjustment based on billet entry temperature and line speed
✅Real-time PLC-controlled feedback with infrared temperature sensors
✅Minimizes billet surface oxidation and improves rolling quality
✅Compatible with continuous casting billet heating production lines
✅Supports square and round billets, lengths 3–12 meters
This fully automated billet preheating and temperature maintenance production line reduces labor, energy consumption, and production downtime.
🔹 Advantages of Billet Heating Production Line
✅Energy-efficient: 40–110 kWh per ton, depending on billet initial temperature
✅High uniformity: precise medium-frequency induction heating ensures temperature consistency
✅Reduced oxidation: surface scale ≤0.5%
✅Automated control: PLC closed-loop system and infrared monitoring
✅Flexible configuration: integrates feeding, heating, and discharge for continuous rolling
✅High reliability: suitable for high-speed, high-volume steel production
The billet heating production line ensures both high efficiency and high-quality billets, supporting modern rolling mill operations.
🔹Working Principle
1. Billets exit the continuous casting machine with residual heat (750–900°C)
2. The continuous casting billet heating production line uses induction coils to raise billet temperature and maintain uniformity
3. Infrared sensors detect billet temperature and automatically adjust power via PLC control
4. Heated billets are conveyed seamlessly into rolling mills, reducing preheating time and energy consumption
