Product Description

1900 Degree Graphite Heating Vacuum Furnace For Annealing Sapphire and Sultanate (Al2O3 (OH))
 
Introduction of 1900 Degree Graphite Heating Vacuum Furnace

Graphite vacuum sintering furnace  is widely used in the heat treatment of metallic material or ceramic parts in low or high vacuum, especially used in the vacuum brazing of the materials like stainless steel, high temperature alloy, hard alloy and nonferrous metal in reducibility or protective atmosphere. Can also be used for special heat treatment of materials such as carbon products in the development process of carbonation.

 
Features of 1900 Degree Graphite Heating Vacuum Furnace
 

1) Small deformation for workpiece

2) Bright surface color without oxidation

3) high vacuum degree up to 7x10-3Pa or even higher

4) Less heat inertia

5) Easy operating

6) Quick cooling
