High-Speed High-Temperature Heating Advantages of Forever Electromechanical Steel Billet Induction Reheating Furnace
Release Date: July 28, 2026
Forever Electromechanical, a professional R&D and manufacturing enterprise focusing on IGBT induction heating heat treatment equipment, has released an in-depth technical report on its flagship steel billet induction reheating furance, highlighting the core competitive advantages of high-temperature rapid heating that outperform traditional gas reheating furnaces, bringing low-consumption and high-yield heating solutions to steel rolling, forging and metal forming factories worldwide.
Traditional gas-fired
billet forging heat treatment process rely on flame radiation heating, which requires a long heat preservation period to ensure uniform internal and external temperature of billets. Long-time high-temperature exposure easily causes severe surface oxidation, decarburization and thick oxide scales on steel billets. Manufacturers need extra sandblasting or shot blasting procedures to remove scale, increasing raw material loss and processing costs. In contrast, Forever’s steel billet induction reheating furnace adopts electromagnetic eddy current internal heating principle, which directly generates heat inside the metal billet, realizing rapid temperature rise from room temperature to forging temperature within 20 to 90 seconds, greatly shortening heating cycle.
The equipment supports continuous high-temperature heating up to 1300°C, meeting the heating requirements of carbon steel, alloy steel, bearing steel and special steel billets for hot rolling and hot forging. Equipped with segmented modular medium-frequency IGBT power supply and multi-group infrared closed-loop temperature detection system, the temperature difference between the core and surface of steel billets is controlled within ±5°C even under ultra-fast heating conditions. Uniform heating effectively avoids internal thermal stress and billet cracking during subsequent rolling, reduces product reject rate by more than 60%, and significantly improves the metallographic structure consistency of finished rolled products.

Energy conservation and environmental protection are prominent highlights of its rapid high-temperature heating performance. The electrothermal conversion efficiency of induction heating reaches over 93%, far higher than the 45% energy utilization rate of traditional gas furnaces. Based on mass production data from cooperative steel plants, this reheating furnace cuts comprehensive energy consumption by nearly 40% for billet heating. Besides, the rapid heating shortens the billet’s high-temperature exposure time, greatly reducing oxidation loss. Metal oxide scale loss can be reduced by over 80%, saving a large amount of steel raw materials for long-term mass production. Meanwhile, there is no flue gas, nitrogen oxide and sulfur pollutant emission during heating, fully matching global environmental protection standards.
Intelligent automatic control matches its high-speed heating capacity perfectly. The whole line integrates automatic feeding, rapid induction heating, constant temperature holding and automatic discharging. Operators only need to set billet size, steel grade and target heating temperature on the HMI touch screen. The PLC system automatically adjusts power and conveying speed to realize stable high-speed continuous production. The induction billet heating machine supports 24-hour non-stop operation, with hourly processing capacity covering 1.2 tons to 10 tons, adaptable to both small-batch customized production and large-scale rolling line matching. In addition, the compact modular structure occupies 50% less workshop space than gas furnaces, and key components can be quickly replaced to minimize equipment downtime.
According to Forever Electromechanical’s technical director, the high-temperature rapid heating design of this
continuous steel billet electric heating furnace targets the pain points of high energy consumption, serious material loss and low production efficiency in the steel processing industry. The company provides customized power, furnace length and automatic assembly schemes for clients, together with one-stop services including layout design, on-site commissioning, technical training and long-term after-sales maintenance.
Industry professionals comment that high-speed induction reheating furnaces will become the mainstream upgrading choice for steel billet heating. Forever Electromechanical will continue to upgrade heating control algorithms, further optimize rapid high-temperature heating performance, and launch customized heating equipment for special alloy billets to help global metal processing enterprises achieve efficient, low-carbon and intelligent production transformation.
