In addition, our Shaft Forging Induction Heating System can be tailored to meet specific industry requirements, enhancing flexibility.
An induction billet heating machine should be sized according to the real billet process, not chosen as a standard machine. Different billet materials, sizes, temperatures, and output targets require different power, frequency, coil design, and line configuration.
To recommend the right solution, we usually evaluate billet material, billet shape and size, billet length, target temperature, heating time, throughput, and automation requirement. If the system needs to connect with an existing line, we also consider the current feeding, handling, and control setup.
Based on this information, we can recommend a suitable heating solution, including power and frequency selection, coil design concept, heating layout, and automation configuration. This helps ensure the system is matched to the actual billet heating process instead of being selected only by rough estimates.
