Against the global backdrop of energy conservation, emission reduction and intelligent upgrading of the metallurgical industry, the new-generation steel billet induction preheating machine has been officially launched and put into large-scale industrial commissioning. As a core upgraded product for steel billet preheating in forging, hot rolling and metal processing production lines, this induction heating equipment completely optimizes the defects of traditional gas-fired furnaces and resistance heating equipment such as high energy consumption, uneven heating and serious oxidation loss, becoming a key intelligent and green equipment for modern steel mills and forging enterprises to reduce costs and increase efficiency.
Different from conventional heating equipment that relies on external flame heat conduction, this high-efficiency induction preheating equipment adopts advanced medium-frequency electromagnetic induction heating technology. It generates uniform eddy current inside the steel billet to realize internal and external synchronous heating, which fundamentally solves the problem of large temperature difference between the surface and core of steel billets caused by traditional heating methods. Industrial test data shows that the thermal efficiency of the equipment reaches 65%-75%, far higher than that of traditional heating furnaces, and the comprehensive energy-saving rate exceeds 25%, effectively reducing enterprises’ long-term production energy consumption costs.
In terms of heating accuracy and product quality control, the equipment achieves outstanding industrial performance. It supports automatic identification of steel billet specifications, material properties and initial temperature, and dynamically adjusts heating power and temperature in real time through intelligent control systems. The heating temperature error of each steel billet is stably controlled within ±15°C, which greatly reduces the oxidation burning loss and surface scale of steel billets. This precise heating feature significantly improves the yield and processing quality of subsequent hot rolling, forging and extrusion products, and effectively reduces product defective rates.

In response to the demands of modern continuous industrial production, the upgraded steel billet induction preheating equipment realizes instant start and stop without preheating waiting time, perfectly matching the high-frequency and continuous operation rhythm of automated production lines. It supports the preheating processing of carbon steel billets, alloy steel billets, round steel billets and various metal blanks, with strong compatibility and flexible customization capabilities, which can be adapted to different production scales from small and medium-sized processing plants to large steel mill production lines.
In addition to efficiency improvement, the equipment highlights green and safe industrial production advantages. Completely abandoning open flame combustion heating, it produces no exhaust gas, smoke and harmful emissions during operation, realizing zero direct CO₂ emissions in the heating link. Meanwhile, the closed heating structure reduces heat dissipation loss, and the low-noise operation design optimizes the on-site production environment, fully complying with global industrial environmental protection and safety production standards. Compared with traditional fossil fuel heating furnaces, it greatly reduces fire hazards and post-maintenance costs.
Industry analysts pointed out that the traditional steel billet heating link has long been a high energy consumption and high pollution link restricting the upgrading of the metallurgical processing industry. The promotion and application of high-efficiency Induction reheating furnace for steel billet marks the gradual replacement of fossil fuel heating by electric induction heating technology in the metal processing field. It not only helps manufacturing enterprises complete energy-saving transformation and meet carbon emission reduction targets, but also promotes the overall intelligent and standardized development of the steel forging and rolling industry.
At present, this series of industrial high-efficiency induction preheating equipment has completed stable operation verification in multiple steel processing and precision forging projects at home and abroad. With its advantages of high efficiency, energy saving, intelligence, environmental protection and low maintenance cost, it has become the preferred supporting equipment for new and upgraded hot rolling production lines, and is expected to be widely promoted in the global metallurgical and metal processing industries in the next two years.
