Medium frequency Heat-through furnace The heating principle is electromagnetic induction, and the heat is generated internally within the workpiece itself. After starting up, ordinary workers can begin continuous forging operations within ten minutes using a medium-frequency induction furnace. There’s no need for specialized furnace operators to perform preheating and sealing procedures in advance. Let’s take a closer look at the features of medium-frequency induction furnaces—hopefully, our netizens will enjoy this information!

Medium frequency Heat-through furnace Characteristics:

1. Fast heating speed, high production efficiency, minimal oxidation and decarburization, and reduced material and die costs.

Because the principle of medium-frequency induction heating is electromagnetic induction, the heat is generated internally within the workpiece itself. After starting up a medium-frequency induction furnace, ordinary workers can begin continuous forging operations within ten minutes, eliminating the need for specialized furnace operators to perform preheating and sealing procedures in advance. There’s also no risk of wasting billets that have already been heated by coal furnaces due to power outages or equipment malfunctions. Thanks to the rapid heating rate of this method, oxidation is minimized, saving at least 20 to 50 kilograms of steel raw materials per ton of forgings compared to traditional coal-fueled furnaces. The material utilization rate can reach as high as 95%. Moreover, since this heating method ensures uniform heating with minimal temperature differences between the core and surface, it significantly extends the service life of forging dies and reduces the surface roughness of forged parts to below 50 microns.

2. Superior working environment, improved worker conditions and company image, zero pollution, low energy consumption.

Compared to coal furnaces, induction heating furnaces eliminate the need for workers to endure the scorching heat and smoke from coal furnaces under the blazing sun. Moreover, induction heating meets all the environmental standards set by regulatory authorities, helping to enhance the company’s external image and align with future trends in the forging industry. Among electric heating methods, induction heating is the most energy-efficient—when heating a ton of forgings from room temperature to 1,100°C, the power consumption is less than 360 kilowatt-hours.

3. Uniform heating with minimal temperature difference between the core and surface, and high temperature control accuracy.

Induction heating generates heat internally within the workpiece itself, ensuring uniform heating and minimizing temperature differences between the core and surface. By using a temperature-control system, precise temperature regulation can be achieved, thereby improving product quality and increasing the pass rate. Medium frequency. Heat-through furnace Heating devices—characterized by their small size, light weight, high efficiency, superior thermal processing quality, and environmental friendliness—are rapidly replacing coal-fired furnaces, gas furnaces, oil-fired furnaces, and conventional resistance furnaces, making them the next-generation metal heating equipment.

4. Fast melting speed, energy-efficient and power-saving, low burn-off, and easy to start.

The main equipment in the medium-frequency induction forging and heat-treatment workshop—its operational stability, reliability, and safety—are essential guarantees for the smooth and stable operation of the continuous-flow forging and heat-treatment production line.
