Induction Heating System for Forge

In the forging industry, medium-frequency induction heating systems are primarily used for fast, efficient, and highly uniform heating of metal billets, bars, and preforms before deformation, making them one of the key heating solutions in modern forging production. Based on the principle of electromagnetic induction, Dinghong equipment converts industrial-frequency AC into medium-frequency current, generating an alternating magnetic field in the induction coil. This field induces eddy currents inside the workpiece, enabling the metal to heat from within—rapidly, precisely, and with excellent controllability.

Compared with traditional gas- or coal-fired furnaces, medium-frequency induction heating delivers higher thermal efficiency, shorter heating cycles, and cleaner operation with minimal smoke and dust. Accurate power regulation and stable output help achieve consistent target temperatures, reducing overheating, decarburization, and oxidation losses, while improving forging quality and reducing scrap. Uniform heating also contributes to better metal flow during forging, lowering forming resistance and helping extend die life.

Dinghong's induction heating solutions can be configured for different forging processes such as die forging, hot upsetting, ring rolling, and hot extrusion. Systems support single-station and continuous heating lines, and can be integrated with automatic feeding, conveying, and temperature measurement to match customer production rhythm and automation needs. With compact installation, easy operation, and high safety standards, our equipment helps customers optimize workshop space and improve production efficiency.

Supported by advanced power-supply technologies—such as 12-pulse rectification tandem designs and energy-saving inverter solutions—Dinghong systems provide stable performance, reduced harmonics, and reliable long-term operation. By combining energy saving, high efficiency, controllable heating, and environmental benefits, Dinghong helps forging manufacturers build greener, smarter, and more competitive production lines.
