What is an Induction Billet Heater

An induction billet heater is an industrial heating system designed to heat metal billets or bars—such as steel, aluminum, copper, brass, and alloys—using electromagnetic induction. When alternating current passes through an induction coil, it creates eddy currents inside the metal, generating heat and bringing the billet to the desired temperature for forging or other metal-processing operations.

Compared with traditional gas or coal furnaces, induction heating provides faster heating, precise temperature control, minimal oxidation, higher energy efficiency, and a cleaner working environment.

Why Choose Duolin’s Induction Billet Heater

Duolin, established in 1994, has more than 30 years of experience in the design and manufacturing of induction-heating equipment. Their heaters cover a wide power range and support various metal materials, making them suitable for both small workshops and high-capacity industrial production lines.
