Vacuum Annealing Furnace Description:
Vacuum annealing furnace is The equipment is used in various alloy materials, devices (tungsten, molybdenum, niobium, tungsten-copper alloy, etc.), magnetic materials, electrical steel, electromagnetic alloys, stainless steel, heat-resistant alloys, copper and its alloys, hydrogen storage alloys, activity and difficulty. Annealing and aging treatment of molten metal. It can also be used for the reduction of diamond and hydrogen storage materials.
The annealing furnace changes the crystal structure, refines the structure, eliminates stress and softens the material to the metal material and the workpiece, and vacuum annealing can prevent oxidative decarburization, degassing and degreasing, and evaporation of the oxide to improve the surface brightness and mechanical properties of the workpiece.
Main application areas: annealing and degassing of active and refractory metals; electrical steel and electromagnetic alloys, stainless steel and heat resistant alloys, annealing of copper and its alloys and steel materials.
Vacuum Annealing Furnace Technical Features
