Compact Vacuum Arc Melting System with 7 Cavities - EQ-SP-MSM207


Product Options

Vacuum pressure gauge:
EQ-SP-MSM207 is a compact vacuum arc melting furnace with a non-consumable tungsten electrode and water-cooled copper crucibles. A built-in mechanical manipulator is included for tilting and rotating metal ingots for the re-melting process. Vacuum casting faction fixture can be added as optional. It is an excellent tool for smelting metal alloys for phase diagram research.

SPECIFICATIONS:
Features

  • Designed for melting samples < 10 g up to 3000 °C 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

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 °C, which can melt all types of metals
  • Pic.A is a 4.5 g tungsten melt drop 
  • Pic.B is a 10 g tungsten melt drop
               
               A.4.5 g         B.10 g 
Copper Crucible
  • Water-cooled copper crucible plate with 7 cavities of 25 mm Dia. × 8 mm depth (Pic 1), 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.
  • Customizable copper crucible is available upon request at extra cost (Pic 2 &3)
  • Vacuum suction casting module can be added to the bottom of the central cavity upon request at extra cost (Pic 4).  Casting rod dia. 6 mm, and Max. weight 30 g

Application & Warning Notes


  • High purity Ar gas is required for the melting operation. Gas purification module is recommended to ensure gas purity. (Click Pic.1 to order)
  • 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 (Pic.2)
  • 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 (Pic. 3)
  • 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.
