Inert atmosphere annealing furnace
Function :
The inert atmosphere annealing furnace is periodic furnace,which apply the low vacuum tempering for the normal metal parts and the heat treatment for the light alloy parts.
Basic components of the inert atmosphere electric furnace:
The inert atmosphere annealing furnace consists of furnace shell, furnace lining,furnace door,jacking system,heating element,vacuum system and the temperature system.
Structure specification:
Furnace shell: Cylindraceous, welded with profiled bar and armor plate.The composite energy efficiency furnace lining consists of light chamotte brick,aluminium silicate fiber felt,sil heat insulator. The lifting and dropping of the furnace cover adopt with electromotor to drive the lifter of worm wheel,worm,and screw mandrel to perform. The airproof of furnace cover and retort adopt appropriativesealing ring and impacted structure.There are the vent and explosion door on the furnace cover.
Retort: Adpot heat resistance stainless stell tight weld,and there is the water cooling installation at the top of the retort.
Heating element: High alloy resistance thread twist on the brick around the furnace chamber.
Vacuum system: It is consists of vacuum sheet of vortex pump,vacuum butterfly valve,vacuum dust catcher,and pipe,instrument,which are easy to be installed and deinstalled.
Controlling system:the standard configuration is KRG6 series controller.There are the imported digital temperature controller and automatic recording,which could show,record and adjust the temperature automatically.It also have the alarm protective function.
We also can adopt the KRG7 series controller according the processing requirement.The accuracy of the silicon control PID regulating electric furnace controller is ±10°c.
