120KW IGBT Induction Heat Treatment Furnace with Water Cooling System for

Induction heating is a growth sector, and for good reasons. The technique is energy efficient, reliable, reproducible, very fast and its range of possible applications is almost unlimited. For example, induction can be used:

• Annealing and normalising
• Bolt heating
• Bonding
• Brazing
• Forging
• Hardening
• Melting
• Paint and coating removal
• Post-heating
• Pre-heating
• Shrink-fitting
• Straightening
• Tempering
• Welding
• Wire and cable heating

Automotive, Electrotechnical, appliances, Renewable energy, Tube and pipe Other important industries them. A critical component in these processes is the inductor. Its design is crucial in determining how precisely a part is heated. Complex manufacturing processes are therefore used to produce this central tool with precision to a tenth of a millimeter-a task perfectly suited to the experts at our factory. Our factory's technicians have a thorough understanding of the different applications of induction heating. For more than 25 years, they have been developing inductors to match, which are adapted to the geometry of the workpiece with painstaking dimensional accuracy.

The crucial quality in induction heating is best summarized by the word "precision." The technology is used anywhere where a lot of energy or heat needs to be applied to a workpiece in a very short time. Temperature accuracy plays an important role here and is often process critical - and precise heating is only possible with the right mix of inductor geometry, frequency, power, and magnetic field characteristics. Furthermore, the application of energy through induction ensures fast production processes, minimal workpiece distortion, and economical energy consum.

1. 1. Energy Efficiency & Cost Savings
   • 90-95% Energy Conversion Rate: Unlike traditional gas or resistance furnaces (30-50% efficiency), induction heating directly generates heat within the workpiece, minimizing energy waste.
   • Reduced Power Consumption: For example, melting steel in induction furnaces consumes 30-50% less energy compared to coal or gas furnaces.
   • Lower Operational Costs: Reduced fuel dependency and minimal refractory material usage lower long-term expenses.
2. 2. Precision & Process Control
   • Uniform Heating: Electromagnetic induction ensures consistent heat distribution, achieving ±1°C temperature control with closed-loop systems.
   • Depth Customization: Adjustable frequency (1 kHz-400 kHz) controls heating penetration depth (e.g., 0.5-5 mm for surface hardening).
   • Automated Integration: Compatible with PLC and IoT systems for real-time monitoring and parameter optimization.
3. 3. Environmental Sustainability
   • Zero Emissions: Eliminates combustion byproducts and reduces carbon footprint by 40-60% compared to fossil fuel furnaces.
   • Minimal Oxidation: Heat treatment in inert atmospheres reduces metal loss (e.g., 0.05-0.5% oxidation vs. 2-3% in gas furnaces).
   • Recyclable Waste: Compatible with scrap metal melting, supporting circular economy practices.
4. 4. Enhanced Product Quality
   • Reduced Distortion: Localized heating minimizes thermal stress, achieving <0.2 mm warpage in precision components (e.g., turbine blades).
   • Improved Surface Integrity: Eliminates decarburization and minimizes surface defects, critical for aerospace and medical parts.
   • Consistency: Automated cycles ensure uniform hardness (e.g., HRC 50-62 for gears) across batches.
5. 5. Operational Safety
   • No Open Flames: Eliminates fire hazards associated with gas torches or coal furnaces.
   • Cooler Work Environment: Reduced radiated heat keeps ambient temperatures 15-25°C lower than conventional furnaces.
   • Emergency Shutdown: Built-in safety protocols (e.g., overcurrent protection) prevent accidents.
6. 6. Versatility in Applications
   • Material Compatibility: Suitable for steel, aluminum, titanium, and composites.
   • Industry Coverage:
     • Automotive: Gear hardening, brake rotor tempering.
     • Wind Energy: Turbine shaft strengthening.
     • Aerospace: Titanium component stress relief.
7. 7. Maintenance & Longevity
   • Low Wear and Tear: No moving parts in induction coils reduce mechanical failure risks.
   • Extended Furnace Life: Ceramic-based insulation materials withstand temperatures up to 1200°C.
   • Reduced Downtime: Modular designs allow quick replacement of worn components.
8. 8. Space Efficiency
   • Compact Design: Induction coils occupy 50-70% less floor space than batch furnaces.
   • Integration with Production Lines: Inline heating systems streamline workflow (e.g., continuous forging).
9. 9. Cost of Ownership
   • Lower Initial Investment: Smaller footprint and simplified infrastructure lower capital costs by 20-30%.
   • Reduced Labor Costs: Automation reduces manual intervention by 60-80%.
