It's maximum oscillation power is 15 KVA, compact HF-15 and split type HF-15AB are available. They are widely used for small parts heating or soldering requirement, widely used for welding, annealing, melting, quenching process in extensive applications.
Application Scope
The 15KVA high-frequency induction annealing machine delivers versatile industrial applications with precision and efficiency. Ideal for diamond saw blade and turning tool welding, it ensures strong carbide bonding with minimal thermal distortion. The system excels in stainless steel cylinder annealing and precious metal (silver/copper) processing, offering uniform heating through programmable 3-stage timing (heating-retain-cooling).
Its rapid 3-second heating capability makes it perfect for hammer quenching and automotive/machinery parts heat treatment (gears, shafts). Operating at 30-100kHz frequency with 220V single-phase input, the machine features water cooling (2-5L/min) and over-current/voltage protection for stable performance. The compact 18-44kg design supports portability while maintaining an 80% duty cycle for continuous operation. With 40% greater energy efficiency than traditional methods, this CE-certified system is a cost-effective solution for diverse metalworking needs, from stress relief to surface hardening applications.
Configuration and Performance
This 15KW high-frequency induction annealing machine features advanced MOSFET/IGBT power modules with European inverter technology, delivering stable 30-100kHz frequency output. The compact 18-44kg unit operates on 220V single-phase power, supporting both fixed and mobile workshop installations. Its digital control panel enables precise parameter adjustments, while the integrated water-cooling system (2-5L/min flow) ensures thermal management during prolonged operations.
Performance-wise, the machine achieves rapid heating within 3 seconds, ideal for applications like diamond tool welding and stainless steel annealing. The three-stage programmable timer (0-99s per stage) automates heating, insulation, and cooling cycles with ±1% temperature accuracy. An 80% duty cycle allows continuous 8-hour operation without performance degradation, backed by over-current/voltage/overheat protection circuits.
