High Temperature Vacuum sintering furnace are used in many applications in all industries. vacuum furnace is normally an electric furnace in which a vacuum is maintained during the process. Most high temperature furnace are heated by electric resistance elements made from graphite, ceramics or metals.
High Temperature Vacuum sintering furnace are used in many applications in all industries. A vacuum is one of the methods to protect heated steel and metal parts from the negative influence of an air atmosphere. A vacuum furnace is normally an electric furnace in which a vacuum is maintained during the process. Most high temperature furnace are heated by electric resistance elements made from graphite, ceramics or metals.
HT high temperature furnace can supply gas heated vacuum sintering furnaces. A gas heated vacuum furnace is not direct heated by open burners, but indirectly as a vacuum retort furnace or a vacuum high temperature furnace with vacuum-tight radiation burner tubes.
The vacuum in the furnace is maintained by vacuum pumps. Depending on the application, a single or combination of mechanical and booster, diffusion and turbo-molecular pumps are used.
A vacuum furnace will heat materials, typically metals, to very high temperatures and carry out processes such as brazing, sintering and heat treatment with high consistency and low contamination.
The processing of components through a vacuum sintering furnace can offer many advantages over conventional thermal Vacuum Furnace treatment routes:
No surface oxidation or discolouration
Minimal distortion
No post cleaning operations
Near finished, machined shape prior to treatment
Flux free brazing
Combined vacuum/atmosphere processing
Repeatable quality
Environmentally acceptable furnaces
Clean, safe, quiet and efficient
Processes and applications include:
Vacuum heat treatment – hardening, tempering and annealing
Vacuum brazing
Sintering
Degassing
Specifications
The max Temperature of high temperature furnace can up to 2000ºC as standard and options for higher temperatures
Double walled, water-cooled carbon or stainless steel chambers
Choice of hot zones including graphite and metal
Fully automatic high, low or custom vacuum systems
Inert gas recirculating fast cool system with internal fan and heat exchanger
Eurotherm instrumentation and PC control
Single or three zone temperature control
Jigs and fixtures standard or bespoke
Horizontal and vertical configurations
Heating metals to high temperatures normally causes rapid oxidation, which is undesirable. A vacuum sintering furnace removes the oxygen and prevents this from happening.
An inert gas, such as Argon, is typically used to quickly cool the treated metal back to non-metallurgical levels (below 204 °C) after the desired process in the furnace.[1] This inert gas can be pressurized to two times atmosphere or more, then circulated through the hot zone area to pick up heat before passing through a heat exchanger to remove heat. This process continues until the desired temperature is reached.
