Vacuum Tungsten Coil Furnace

High Temperature Vacuum Tungsten Coil Furnace Up to 2200℃

Vacuum tungsten coil furnace adopts tungsten coil as heating elements, pollution-free. Because retains its strength at high temperatures and has a high melting point, elemental tungsten is used in many high-temperature applications. In addition, Tungsten is extremely corrosion resistant. The advantages of using Tungsten electrical heating elements are its high mechanical and thermal stability, low creep deformation and long life span.

Application

This Vacuum Tungsten Coil Furnace mainly used for the heat treatment of ceramic, melting, and sintering of high melting point metals, alloys, sapphire glass, zirconia in a high temperature vacuum environment. can also be used on some metal light, degassing treatment, etc.

Widely used in inorganic materials such as zirconia, ceramic seals, alumina, zinc dioxide, etc. and metal materials such as sintering hard alloy in a vacuum or protective atmosphere. can also be used to clean the required material for the heat treatment of the sintering environment. Also used for universities and research centers for mass production.

Featurers

  • Specially designed tungsten net heating and tungsten foil as the thermal insulation scre, the max. temperature can be 2200℃
  • Vacuum system can choose turbo pump, the ultimate vacuum can be 6×10^(-5)Pa.
  • Can inlet N2, Ar, H2, N2, and H2 mixed gas, etc.
