Steel Billet Induction Heating Machine for Forging | Forever

1. Background: Forging Industry Shifts Toward Low‑Carbon Heating Solutions

Global forging manufacturers are accelerating the phase‑out of traditional gas-fired furnaces, driven by stricter emission rules, rising fuel costs and higher requirements for forging blank quality. Conventional flame heating brings obvious drawbacks: uneven internal and surface temperature, heavy oxide scale loss, long standby preheating time and low thermal efficiency. Many forging plants urgently need reliable electric heating equipment that adapts to both round and square steel billets. Against this market demand, our upgraded

steel billet induction heating furnace for forging has been officially released, targeting pre-forging through-heating of various carbon steel, alloy steel billets.

2. Core Technical Design for Round & Square Billets

This induction heating equipment adopts mature IGBT intermediate frequency induction power supply and multi-zone segmented heating structure. Different coil modules are configurable to fit round billets and square billets of different sizes. The whole line is equipped with automatic feeding, servo conveying, centering correction and infrared closed-loop temperature measuring system. The real-time temperature feedback adjusts power dynamically to keep temperature deviation within a narrow range. Unlike single-zone heating, segmented preheating reduces thermal shock on billets, effectively avoiding internal crack risks caused by rapid temperature rise. The heating depth can be adjusted according to forging process requirements, realizing synchronous heating of core and surface.

3. Key Advantages Over Traditional Gas Furnaces

Energy saving and low oxidation are the most prominent strengths. Induction heating generates heat inside the metal billet directly, with no heat loss for heating furnace lining and air. Its thermal efficiency is far higher than gas furnaces. Short heating time greatly reduces oxide scale, improves material yield and cuts raw material waste. It supports instant startup and shutdown, no need for long-time preheating, which suits intermittent and flexible production schedules. The whole working process has no open flame, no flue gas emission, meeting environmental standards for overseas factories. Compact layout saves workshop space, and it can be docked seamlessly with forging presses, skew rolling machines and subsequent heat treatment lines.

4. Flexible Application for Multiple Forging Scenarios

The equipment covers a wide processing range, compatible with round billets and square billets widely used in grinding ball forging, shaft blank forging, engineering machinery parts and oil tool blank production. It supports customized power, coil size and line speed according to customer output. For small-batch diversified production, single independent heating unit is available; for large-scale continuous forging workshops, multi-module combined continuous heating lines can be supplied. Our technical team provides one-stop service including scheme design, factory test, on-site installation, operator training and after-sales maintenance.

5. Market Outlook: Induction Heating Becomes Mainstream Forging Heating Trend

More overseas buyers from mining equipment, auto forging and petroleum component industries choose electric induction heating solutions. As global low-carbon transformation continues, the demand for billet induction heating equipment will keep growing. This round and square billet induction heating furnace fills the demand gap of medium and large forging enterprises for stable, automatic and eco-friendly pre-forging heating equipment. We will continue to optimize intelligent control functions, develop higher-power modular systems and deliver reliable induction heating solutions for worldwide forging customers.
