Steel billet induction heating line | Continuous Forging & Rolling

Introduction

Forever Electromechanical, a seasoned developer and manufacturer of induction thermal processing equipment, has launched its upgraded Continuous Induction Heating Line for Steel Billet Hot Forging & Rolling. The new system addresses long-standing bottlenecks in traditional billet reheating, including excessive energy use, uneven temperature distribution, heavy scale formation and intermittent production. Designed to connect seamlessly with downstream forging presses and rolling mills, this continuous heating line delivers stable, repeatable preheating for steel billets, supporting high-volume production for metal forging, steel rolling and grinding media manufacturing projects worldwide.

Industry Pain Points of Traditional Billet Reheating

For decades, gas-fired furnaces have dominated billet reheating for hot forging and rolling. While widely adopted, they carry obvious drawbacks. Flame heating creates large temperature gradients between billet surface and core, leading to inconsistent metallographic structures after forging or rolling. Heavy oxidation forms thick oxide scale, reducing material yield and increasing machining waste. Gas furnaces also require long startup and shutdown cycles, making them inflexible for variable batch sizes. In addition, combustion generates exhaust emissions, raising compliance costs for manufacturers operating under strict environmental regulations. Many producers also struggle with high fuel bills and frequent maintenance on burner systems.

Core Technical Advantages of Forever Continuous Induction Heating Line

The new heating line adopts segmented multi-stage induction heating layout paired with self-developed full-digital IGBT medium frequency heating power supply. The preheating zone applies gentle temperature rise to reduce thermal shock on cold billets, followed by rapid through-heating in the main heating section. Real-time infrared temperature sensors feed data back to the PLC closed-loop control system, automatically adjusting power and conveying speed according to billet dimension, steel grade and target forging temperature. The cross-section temperature deviation can be controlled within ±3℃, ensuring uniform microstructure after hot working.

Compared with gas furnaces, the induction line cuts oxidation loss significantly, improving material yield. It eliminates flue gas and combustion waste, satisfying green manufacturing standards. The IGBT power unit removes idle power consumption, bringing overall energy savings of 18–28% versus conventional reheating equipment. The whole line supports non-stop continuous feeding and discharging, matching the rhythm of fully automatic forging lines such as forged grinding steel ball production.

Flexible Integration with Downstream Production

A key design highlight is its strong compatibility. The steel billet induction heating production line can be integrated with upstream continuous casting machines and matched to downstream hot forging units, rolling mills or grinding ball forging lines. It supports rapid parameter switching for round billets, square billets and multiple steel grades, suitable for mixed-specification production. Operators can set recipes on the HMI touchscreen; the system records all production data and triggers fault alarms automatically. Only a small operating team is required for supervision, lowering labor cost and technical threshold for workshop staff.

Global Application & After-Sales Support

Forever Electromechanical has completed full-load factory testing of this billet induction heating line. The equipment is CE-certified and ready for export to Europe, the Middle East, Southeast Asia, Russia and Latin America. The company provides full lifecycle services including customized engineering design, factory testing, overseas installation guidance, operator training and remote technical support.

Conclusion

As global metal processing industries shift toward low-carbon, intelligent manufacturing, induction reheating technology is replacing traditional combustion furnaces. Forever Electromechanical’s continuous induction heating line offers a reliable, energy-efficient solution for steel billet hot forging and rolling. By combining precise temperature control, continuous operation and flexible integration, the system helps metal forging and rolling enterprises boost product quality, cut raw material and energy costs, and meet tightening environmental requirements. Forever will continue to upgrade induction heating and heat treatment equipment to serve global partners in mining, cement, construction machinery and metal forging sectors.
