Advantages of IGBT MF induction melting furnace
Independent R&D and mature technology: The IGBT technology is independently developed and has reached a high level of maturity. Through continuous experience accumulation and iterative improvements based on real-world operational issues, the equipment has now become highly reliable and technically mature.
Real-time water temperature monitoring system: Temperature sensors are installed on every cooling water pipe, enabling continuous, real-time monitoring of all circuits. If any abnormal water temperature is detected, the system immediately triggers an alarm, displays the exact location of the fault, and provides troubleshooting guidance—allowing operators to quickly identify and address the issue.
Fully sealed cabinet design: The cabinet and door are sealed with rubber gaskets, significantly reducing the ingress of external dust and thereby enhancing overall equipment stability and reliability.
Automated air conditioning control: The internal cabinet air conditioner is automatically synchronized with the main equipment—turning on when the equipment starts and turning off when it shuts down. This eliminates the risk of operators forgetting to operate the air conditioner manually.
Comprehensive protection mechanisms: Drawing on years of operational experience, the equipment incorporates robust protective features—including overcurrent, overvoltage, water shortage, and phase-loss protection. These safeguards ensure that even in the event of operator error, the equipment remains protected from damage.
Disadvantages of IGBT MF induction melting furnace
High requirements for operating environment and maintenance: Due to the high inverter voltage of the IGBT medium-frequency induction furnace, as well as its more complex manufacturing process and structural design compared to KGPS (thyristor-based) systems, it is more precision-sensitive and thus demands stricter environmental conditions and more rigorous maintenance protocols.
Higher repair costs: The critical IGBT modules are imported from Germany and classified as consumable components. Consequently, any failure involving these parts results in relatively high repair and replacement expenses.
Higher initial investment: Compared to KGPS systems, the upfront cost of IGBT-based equipment is approximately one-third higher—or even more—making the initial capital outlay significantly greater.
