Main Components
Frequently Asked Questions
What materials can be processed with these industrial annealing systems?
Our systems are highly versatile and designed to process carbon steel, stainless steel, copper alloys, brass, and various wire products.
What is the temperature range for gear annealing?
Gear annealing typically requires heating the workpieces to a range of 700-850°C, followed by slow cooling (either furnace or air cooling) to eliminate machining stress and optimize toughness.
How does the system prevent oxidation during the annealing process?
The system offers an optional inert gas control system (using Nitrogen or Argon) to ensure bright, oxidation-free surface finishes, which is especially critical for brass and stainless steel.
What are the frequency options available for different parts?
The frequency range spans from 3-50kHz. We utilize medium-frequency (3-10kHz) for deep heat penetration in gears, high-frequency (20-50kHz) for rapid heating of copper and brass, and dual-frequency options for thick/thin-walled stainless steel tubes.
What are the key advantages of induction annealing over traditional furnace methods?
Induction annealing provides rapid heating cycles (often under 2 minutes), uniform temperature distribution, and up to 30% less power consumption compared to traditional furnace annealing.
Is the machine compatible with automated production lines?
Yes, the system is equipped with intelligent PLC and touchscreen controls and features complete compatibility with robotic loading systems for continuous 24/7 mass production.
