Heat Treatment Process
Step 1: Workpiece Loading
Metal workpieces are placed on the graphite support platform inside the vacuum chamber according to the required loading plan.
Step 2: Vacuum Pumping
The vacuum system reduces chamber pressure to the required working vacuum level, helping create a cleaner heat treatment environment.
Step 3: Controlled Heating
The graphite heating system raises the furnace temperature according to the programmed heat treatment curve.
Step 4: Temperature Holding
The furnace holds the workpieces at the required temperature to support uniform thermal processing.
Step 5: Gas Quenching
High-purity nitrogen or argon is introduced into the furnace and distributed through internal nozzles for uniform gas cooling.
Step 6: Cooling and Unloading
After the workpieces cool to the required temperature, the furnace can be opened for unloading and downstream inspection.
