Features | Φ120mm front door for easy sample loading/unloading A tinted observation window is installed on the front for instant monitoring of the entire melting process. Water cooled vacuum chamber(φ300mm × 320mmH), cold copper crucible and electrode Electrode position (height) adjustment via hand wheel turning Integrated mechanical manipulator made of stainless steel 1Cr13 can repeatedly tilt/rotate multiple metal ingots without breaking the vacuum Water cooled copper hearth allow smelting multiple samples without cross contamination upto 3000°C |
Vacuum Pressure Gauge | Please select the anti-corrosive capacitance diaphragm gauge or mechanical vacuum pressure gauge from option bar. Digital pressure gauge is used for vacuum chamber Mechanical pressure gauge is used when continuous flow of inert gas inside the chamber |
Power supply | Input Voltage: Single phase AC 220V+/- 15% . 50/ 60Hz (Three Phase AC 380V 50Hz is available upon request) Input Power: 6.3KW, 30A Max. Output Power DC, 56V (OVC), 10 - 190A max. adjustable Optional: larger current upto 300A is available at additional cost. |
Max. Temperature | ~ 4000°C , almost can melt all type metal ( < 10 g ) Bottom-left picture is a 4.5 g tungsten melt drop Bottom-right picture is a 10g tungsten melt drop |
Vacuum Chamber & Copper Hearth | Vacuum chamber: Φ200mm×350mm, made of stainless steel with water cooling jacket Water cold copper hearth with 7 crucibles of 25mm dia.x 8 mm depth ( see the first pic on left ) Solidified sample is about 20 mm half-round button in max. and sample weight is depended on material density. Customized copper hearth is available upon request ( see the second pic on left ) Sample weight for each crucible can be estimated as: W (g) = 2/3 π r3 d ( d= density, g/cm3) |
Electrode | 4 mm dia. Tungsten electrode with water cooling Top hand wheel can move electrode cycle, upward and downward ( max. 30 mm) to melt seven sample in one batch |
Water Chiller & Gas (Optional) | Water cooling is required ( not included ) for its chamber, copper mold and electrode. Please consider to use the KJ-5000 recirculating water chiller. High purity Ar gas is required ( not included ). You may use 5% H2 + 95% Ar gas to better reduce oxidation |
Vacuum Pump (Optional) | Vacuum Level is dependent on the vacuum pump used: 1E-3mbar via mechanical/roughing pump (please click underline to view Roughing Pumps) 1E-5mbar via turbo pump. We strongly recommend you consider Turbo-molecular Vacuum Pump Station for high quality melting. |
