System Structure |
• Air-tight joint between the four furnace tubes and glove boxto protects the sample from oxidation in the preparation.- • Vertical loading of four samples inside the glove box. An electromagnetic release mechanism from top flange can release the sample into the quenching chamber at the bottom.
- • Electric gate valve at the bottom of the tube can isolate the heating chamber from the quenching chamber and open for sample drop when quenching is needed.
- • Both Electromagnet sample release flange and the bottom gate valve are with water cooling jackets which help protect Viton sealing gaskets from over-heated.
|
Input Power
|
• AC 208-240V Single Phase, 50/60 Hz- • 1.5 KW (for glove box); 2.5 KW (for four furnaces)
- • Total: 4.0 KW
|
Glove-Box
 |
• Gas purification station is integrated to ensure a low O2 & H2O environment (<1ppm) in the glove box.- • Case Material: Stainless steel 304 with 3 mm thickness
- • Chamber dimension: 1200 mm L x 740 mm W x 900 mm H
- • Openable front window panel (tempered glass, 8 mm thick) for easy device loading
- • Please click Picture left for detail specification
|
Electromagnet Release &
Quenching Media Tank
|
• 4 sets of Electromagnet Auto-drop Mechanism are installed with the furnace for sample release under atmosphere controlled environment.- • Hinged plate with a hook & cable can hang the sample in the hot zone for heat treatment.
- • Hinged plate releases when the electromagnet is powered off. Then the sample falls into the quenching tank.
- • Rings attached to the top flange for hanging the quartz block to prevent heat dissipation.
- • Improved top flange design allows easy sample reload without uninstalling all parts of the flange.
- • Bottom flange is connected with a 4" gate valve ( electrically operated ) via CF-100 adaptor.
- • Four gate valves are connected to with a quenching media container separately
- • Four quenching container are airtight and connected to a vacuum pump .
- • Note: It is suggested to use oil (such as diffusion pump fluid) as quenching agent if quenching under vacuum.

Application Notes
Click here to learn how to install a gas regulator.
| - • The tube furnaces with mullite tube are designed for using under vacuum and low pressure < 0.02 Mpa / 0.2 Bar/ 3 PSI
- • Never use graphite crucible in 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. - • Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the
furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during
the heating process; please open the gas release valve immediately once the chamber pressure has reached
over 3 PSI to prevent unforeseeable damages. - • The flow rate for gasses should be limited to < 200 SCCM ( or 200ml/min )
- • Vacuum limit definition for all mullite tube furnaces: * Vacuum pressures may only be safely used up to 1300°C
