High Vacuum Crystal Furnace
Usage Profile:
High vacuum crystal furnace adopts induction heating and resistance heating, and can use crucibles such as iridium, platinum, graphite and molybdenum.
Main uses and scope of application:
It can grow oxide crystals (such as YAG: Nd, Al2O3, TeO 2, LiTaO 3, LiNbO 3, etc.). It is an excellent and reliable equipment for research and production of new crystal materials in scientific research institutes, enterprises and institutions by pulling, descending, foaming and temperature gradient methods.
Main functions and characteristics:
High precision lead screw and high quality motor make the transmission system more accurate and stable.
Modular circuit design makes the control circuit more stable, reliable and easy to maintain.
High precision weight sensor ensures excellent automatic diameter control performance.
Full computer control, crystal shape control is better, less manual monitoring.
The key parameters are presented in real time, and the crystal growth process is clear at a glance.
Emergency automatic processing, equipment and crucible to provide a certain degree of security.
Technical parameters:
01. The principle of heating is induction heating. The crucible is in a quartz tube and is encapsulated in an outer shell. Molecular pump external.
02 Quartz barrel 80x90x400 is used to place crucible insulation material.
03 Intermediate Frequency Power 15KW, 2.5kHz
04 Vacuum 5*10-3PA Cold Furnace Limit Vacuum
05. Slow pull 0.1-10mm/h
06. Quick lift 10-70 mm/min
07 Rotating speed 0.1-50r/min
08 crucible 35 x 35, can be heated to 1600 degree material Pt.
09. The lower part is sealed with quartz barrel, and the circulating water is forced to cool. Vacuum pumping interface, inflatable port.
10. Upper seal and quartz barrel seal, forced cooling of circulating water, interface with up-lift bellows
11. Rotating mechanisms, including rotating motors, rotating sealed magnetic fluids
12. The rotating mechanism of the lifting mechanism is installed on the moving block of the lifting mechanism. The lifting mechanism includes stepping motor, reducer, ball screw, guide rail, column and column rotation mechanism.
13. HMI is used to set up lifting interrogation program, run, stop, pause, IF start and stop. Lift control includes slow rise, slow fall, fast rise and fast fall and speed size.
Rotation control includes: forward, reverse, stop, speed.
14. Indicator lights, red, yellow and green, for fault alarm
