Small high temperature precision vacuum lab electric arc furnace price

Features

· Designed for melting samples < 10g up to 3000℃ under tiny positive pressure or low vacuum

· Water-cooled vacuum chamber, electrode, and copper crucible allows arc melting of multiple samples without cross-contamination

· Powerful arc melting power supply enables reliable, stable arc ignition

· Easy electrode tilting and height adjustment via a handwheel

· A built-in mechanical manipulator for tilting and rotating samples without breaking the vacuum

· A tinted observation window on the front for monitoring melting process

Vacuum Pressure Gauge

Please select either an anti-corrosive capacitance diaphragm gauge or a mechanical vacuum pressure gauge.

Power Supply  

· Input voltage: 110 or 220 VAC selectable, single phase

· Input current: 34A max. (One 40A breaker is installed in the power supply. Recommended wall breaker amp ≥ 40A)

· Output DC output: 15 V / 125 A at 35% duty cycle - 110 V input

                                     18 V / 185 A at 35% duty cycle - 220 V input

· Minimum DC current output: 5 A

· Pulse DC and AC output modes available

· Foot pedal control of the output current

Tungsten Electrode

· 4 mm Dia. tungsten electrode with water cooling

· Easy electrode tilting and height adjustment (30 mm max) for multiple-cavity melting

· Capable of melting samples < 10 g up to 3000℃, which can melt all types of metals

Copper Crucible

· Water-cooled copper crucible plate with 7 cavities of 25 mm Dia. × 8 mm depth , especially important for refractory metals comparing to ceramic or graphite crucibles, such as zirconium, titanium, vanadium and their alloys, as these materials are very reactive.

Vacuum Chamber

Water cooled vacuum chamber with dimensions of Φ 182 mm × 225 mm H

· A Φ120mm front door for easy sample loading and retrieving

· A tinted observation window on the front for monitoring melting process

· A built-in mechanical manipulator for tilting and rotating samples without breaking the vacuum

Vacuum Pump (Optional)

· Vacuum level is dependent on the vacuum pump used:

o 10^-3 torr via a mechanical/roughing pump. (Roughing Pumps) 

o 10^-5 torr via a turbo pump. We recommend our Turbomolecular Vacuum Pump Station for best performance 

Water Chiller & Gas (Optional)
    

· Water cooling is required (not included) for the chamber, copper mold, and electrode. Please consider our KJ-5000 recirculating water chiller.

· Water tube for CY Water Chiller is Size: 12mm O.D x 8mm I.D

· High purity inert gas with at least 5N purity (>99.999%) is required (not included)

· 5% Hydrogen + 95% Argon gas may be used to prevent oxidation during melting process

Furnace Dimensions 
     

· 540 mm W × 540 mm D × 920 mm H (exclude the power supply) 

· Power supply dimension: 320 mm L x 185 mm W x 485 mm H

Chamber Dimensions

     Φ182 mm × 225 mm

Net Weight

50 kg

Compliance

CE certified

Warranty

One-year limited warranty with lifetime support

Application & Warning Notes

· High purity Ar gas is required for the melting operation. Gas purification module is recommended to ensure gas purity.

· A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 psi for safe operation. To avoid any damages to the mechanical pump or turbo pump, please install an Inline Particle Trap (maximum 1E-4 Torr vacuum with turbo pump) on the pump inlet port

· Must Wear Welder Glass or Auto Welding Shade while observing the Arc while welding. 

· An example of the system setup with turbomolecular pump can be on the left

· The unit is designed for arc melting operation under tiny positive pressure or low vacuum (0.01 – 0.11 MPa pressure, or positive 0.01 MPa to negative 0.09 MPa pressure). Never operate the unit at high vacuum or high positive pressure!

· During arc melting operation, never allow the electrode to touch the material or the copper crucible! Do not operate the mechanical manipulator during the melting process.

· Option: The user may use a quartz tube shielding to effectively reduce the splash and spilling while arc melting. Please click pic 4 to watch the demo video
