(1) Rapid heating, high production efficiency, minimal oxidation and decarburization, and savings on material and forging die costs
Based on the principle of electromagnetic induction, heat is generated internally within the workpiece. Workers can begin continuous forging operations just ten minutes after starting up the medium-frequency induction furnace, eliminating the need for specialized furnace operators to handle pre-heating or furnace sealing tasks. There is no risk of wasting pre-heated billets-a common issue with coal-fired furnaces during power outages or equipment failures.
The rapid heating rate minimizes oxidation; compared to coal-fired furnaces, this method saves at least 20–50 kg of steel raw material per ton of forgings, achieving a material utilization rate of up to 95%.
Uniform heating and minimal temperature difference between the core and surface significantly extend the service life of forging dies, while the surface roughness of the forgings remains below 50 μm.
(2) Superior working environment, improved conditions for workers, enhanced corporate image, pollution-free, and low energy consumption
Unlike coal-fired furnaces, induction furnaces spare workers from intense heat and smoke. This method meets environmental protection standards while projecting a positive corporate image and aligning with the future development trends of the forging industry.
(3) Uniform heating, minimal core-to-surface temperature difference, and high temperature control precision
Because heat is generated internally within the workpiece, heating is uniform with a negligible temperature difference between the core and the surface. The application of temperature control systems enables precise temperature regulation, thereby improving product quality and the pass rate.
