How the Furnace Works
Step 1: Load the Workpiece
The workpiece is placed inside the furnace chamber according to process requirements.
Step 2: Vacuum Pumping
The vacuum system removes air from the chamber to create a controlled vacuum environment.
Step 3: Heating Process
Graphite heating elements heat the chamber evenly. The furnace can work within 500–1250°C under vacuum conditions.
Step 4: Controlled Atmosphere Gas Cooling
High-purity nitrogen or argon is introduced for gas cooling. The cooling system helps complete the quenching process quickly and uniformly.
Step 5: Automatic Process Control
PID or PLC control helps manage heating, vacuum, gas cooling, and process timing for stable repeatability.
