China Heat Induction Normalizing Machine for Auto Gears, Turbine Blades, and Crankshafts - Reliable Suppliers & Factory
Product Description
The Hongye induction normalizing machine provides advanced heat treatment solutions for high-performance automotive and aerospace components. Its electromagnetic heating technology enables precise austenitization (850-950°C) with controlled air cooling, optimizing grain structures in critical parts like 20CrMnTi auto gears, Inconel 718 turbine blades, and QT800-2 crankshafts. The system ensures ±5°C temperature uniformity and adjustable cooling rates (3-15°C/s), delivering consistent hardness (160-220HB) while minimizing thermal distortion. With automated process control and 30% energy efficiency over traditional furnaces, it meets the demands of high-volume manufacturing for superior metallurgical properties and dimensional stability.
Application Scope
The industrial induction normalizing machine is specifically engineered for critical heat treatment applications across automotive and aerospace sectors. Its primary application scope covers precision normalization of high-performance components including 20CrMnTi auto gears (for dimensional stability in transmission systems), Inconel 718 turbine blades (to enhance creep resistance at 650°C+ operating temperatures), and QT800-2 crankshafts (optimizing fatigue strength in combustion engines). The system's electromagnetic heating technology ensures uniform austenitization (850-950°C) with controlled cooling rates (3-15°C/s), effectively refining grain structures while maintaining ±5°C temperature consistency. It serves as essential pretreatment for subsequent processes like carburizing or quenching, particularly for mass production of drivetrain components, jet engine parts, and heavy-duty powertrain assemblies where microstructural homogeneity and 160-220HB hardness are mandatory specifications.
Configuration and Performance
The Hongye induction normalizing machine features a modular design with a high-frequency power supply (50-500kHz), precision induction coils (customizable for part geometry), and automated conveyor system is selective for continuous processing. Integrated thermal detect and display and pyrometers enable real-time temperature monitoring, while PLC-controlled air nozzles adjust cooling rates (3-15°C/s) dynamically. The system supports batch or inline production with a 6-axis robotic loader option.
Delivering ±5°C temperature uniformity, the machine achieves full austenitization (850-950°C) within 60-180 seconds, refining grain structures to ASTM 5-7 levels. Post-normalization hardness ranges 160-220HB (auto gears) to 280-320HB (turbine blades), with <0.1mm/m distortion tolerance. Energy consumption is optimized at 300-400kWh/ton, 30% lower than chamber furnaces.
Designed for 24/7 operation, the system maintains 98% uptime with water-cooled components rated for 50,000+ cycles. Smart diagnostics predict coil lifespan (8,000-10,000 hours) and auto-calibrate power output. Compliant with AMS2750E and IATF16949 standards for aerospace/automotive applications.
