Vacuum Annealing Furnace
Vacuum annealing process is widely used in manufacturing, depending on the purpose of annealing the workpiece, the specification of the annealing process can be different: full annealing, spherical annealing, stress relief annealing and so on. It should be noted that the degree of vacuum in vacuum annealing should be considered according to the oxidation characteristics of the material being processed, some rare metals will evaporate when heated under high vacuum environment, and should be transferred to low pressure gas for protection. The effect of degassing during vacuum annealing depends on the heating temperature of the vacuum furnace, vacuum, operating time and other process conditions, as well as on the physicochemical properties of the gas and metal oxides.
The role of vacuum annealing
(1) Reduce hardness and improve cutting properties.
(2) Reduce residual stress, stabilize size, reduce deformation and cracking tendency.
(3) Clarify the grain, adjust the organization and eliminate organizational defects.
(4) Unify the structure and composition of the material, improve the properties of the material, or prepare it for subsequent heat treatment.
(5) Improvement of alloy surface organization by vacuum degassing treatment.
Composition of Vacuum Annealing Furnace
Vacuum annealing furnace is mainly composed of furnace body, vacuum system, heating system (furnace lining), forced cooling system, water cooling system, electrical control system and so on. The main role of vacuum annealing furnace is to pump the furnace body into vacuum, the working process is to meet the heating requirements of the material in the vacuum state of the furnace, when the workpiece is heated, according to the different materials on the workpiece technological requirements to complete the heating, the furnace is filled with inert gas as the medium cooling, start forced cooling system on the workpiece for cooling (or so that the workpiece as circulation water cooling naturally) when the furnace temperature reaches the discharged material When The temperature in the furnace reaches the unloading state, the workpiece can be unloaded, and the process is completed.
