CUSTOM VACUUM FURNACE

VERTICAL VACUUM FURNACE

Product Features and Special Configuration

First, preparation work

Check the water level of the pool: if there is no water, fill it with water. The water source switch is on the side of the toilet sink (pool
There is also a switch on the side, usually normally open)
Power cabinet (power supply): Turn on the main switch, compressor, and water pump in sequence.

Control cabinet

First open the control cabinet main power (on the right side)
Press the Job Allow button to check for an alarm (the next step is started without an alarm).
(Water pressure is lower than 0.08MPa or water temperature is higher than 40 °C, water cooling alarm)

Place the sample

Close the vacuum gauge 2 Open the door 3 Discharge 4 Place the sample
furnace door closed (make sure the door is closed and the red light is on)

Programming

Prog + Func (press simultaneously): Start the setup procedure 2 Set the program according to the experimental conditions

Optional:

Furnace: full carbon steel / inner stainless steel / all stainless steel;
Vacuum pump: foreign brand / Chinese brand;
Operation panel: touch screen / industrial computer;
Temperature controller: SHIMADEN / EUROTHERM;
Insulation: all molybdenum / molybdenum plus stainless steel;

features:

Heating is heated by multi-stage temperature control to ensure good temperature uniformity in the temperature zone.
Heating under vacuum can remove the grease and oxide film on the surface of the workpiece, so the surface brightness of the part is high.
No flux is required and no post-weld cleaning is required.

Precautions

When not doing the experiment, vacuum the furnace, open the rotary vane pump, Roots pump, low vacuum valve, and pump for 10 minutes. Shut down again!
The furnace is a horizontal single-chamber horizontal charging structure, and can also be designed as a three-chamber continuous vacuum brazing furnace;
High temperature molybdenum heating zone heating, molybdenum and multi-layer stainless steel mesh form a full metal insulation furnace, and the temperature uniformity is good;
The inlet of the vacuum system is equipped with a gas condensation phase shifter and a filter collection device to eliminate the flux evaporation gas on the vacuum pump set contaminants;
Unique anti-pollution technical specifications to ensure long-life vacuum regulation;
The furnace has interlocking functions such as temperature, pressure, water pressure and vacuum, and has high safety protection and protection functions;
Features such as remote control operation, remote fault diagnosis and remote program update;
