Furnace Structure
|
- Double-layer steel case with two cooling fans which ensures low surface temperature
- YSZ fibrous insulation is used as internal refractory
- High-purity fibrous alumina insulation is used as external refractory
- Included vacuum flange with 30 mm quartz window. The laser beam can penetrate the furnace through the window and sapphire thermal block.

|
Normal Heating/Cooling Rate
|
5°C /min |
|
Heating Zone Length
|
- Three zones: total length: 610 mm (Z1 & Z3 = 195 Z2 = 220 mm)
- Constant temperature zone: 300 mm (if set up three-zone at 1600°C)

Tube Size & Vacuum Flange
|
- 99.8% purity Alumina Tube
- 60 OD x 54 ID x 1200mm L
- 60 mm stainless steel water cooling vacuum sealing flange with valve and meter is included
- special quick clamp flanges for easy installation
- 30mm Dia x 3 mm double-side polished single-crystal window installed on the flange, which allows the laser beam to go through the tube
- In order to block heating radiation and make the laser bean transparent, Two sapphire rods with two ends polished must be placed inside the furnace ( please order separately )
- 16L/min water chiller is required for cooling flange, please click the picture -right to order separately
|
Temperature Control |
- Three digital controllers via SCR (Silicon Controlled Rectifier) power control with phase angle fired
- Each controller is 30 programmable segments for precise control of heating, cooling rate and dwells time
- Built-in PID Auto-Tune function with overheating & broken thermocouple protection
- Over-temperature protection and alarm allow for operation without attendant(s)
- +/- 1 ºC temperature accuracy
- Three B-type thermocouples (one for each zone)
- RS485 Communications Port
|
European Temperature Controllers (optional upgrade)
|
- 1 heating channel
- 1 program of 8 or 24 segment
- Alarm Relay: Form 'A' and Form ‘C’ built-in
- Digital Communications: RS485
- Temperature Accuracy: ± 0.1ºC
-
Recipes: Using a PC tool recipes can be created that can be used to change the operating parameters of the 3000 simply by selecting a new recipe via the HMI. This is very useful where multiple products are processed using the same controller but require different parameters to be set.

Warnings
Please click here to learn the installation of a gas regulator.
|
- The tube furnaces with alumina tube are designed for use under vacuum and low pressure < 0.02 Mpa
- Never use a graphite crucible in the alumina tube.
- Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
- The gas flow rate should be limited to < 200 SCCM ( or 200ml/min )
- Vacuum limit definition for all alumina tube furnaces: * Vacuum pressures may only be safely used up to 1500°C
