SP-MSM-800A is a complete turn-key arc-melting system with a water-cooled high vacuum chamber, 5 melting cavities, vacuum casting, and electromagnetic stirring. It allows researchers to explore the next generation of alloy.
Features：
- Water-cooled SS vacuum chamber which can reach vacuum up to 10-6 torr
-
Powerful arc melting power supply, which enables arc ignition without touching the sample
-
Water-cooled copper hearth with various types of crucibles and functions.
-
The arc electrode is driven by the electric motor for upward or downward motion. (100 mm stroke distance)
-
A wobble stick is built-in for sample flipping without breaking the vacuum
SPECIFICATIONS:
| Power Supply |
- Input: 460 VAC, 3ph, 80 KW, 50/60Hz
- Optional: 380 VAC
|
Melting Chamber
|
- High vacuum water-cooled chamber with a cooling-water jacket made of SS304
- Vacuum level: 5×10^-6 torr via a 1200L/s turbopump, or higher vacuum with larger turbopump.
- Leakage: <5.0 x 10^-4 (mbar·l)/s (5.0 x 10-5 Pa·m3/s).
- The chamber size: 400mm Dia x 350mm L
- Two tinted observation windows (dia. 100 mm) on the front for monitoring the melting process
- Hinged front door
- The sample manipulator is built-in for sample flipping without breaking the vacuum
- Easy sample loading and unloading by the chamber lifting mechanism.
