Vacuum furnaces can implement vacuum hardening and tempering, vacuum annealing, vacuum solid solution and aging treatment, vacuum sintering, vacuum chemical heat treatment and vacuum coating, etc.
Therefore, vacuum furnaces can perform complex processes that other heat treatment equipment cannot perform.
Vacuum furnace classifications include vacuum brazing furnaces, vacuum gas quenching furnaces, vacuum sintering furnaces, vacuum annealing furnaces, vacuum quenching furnaces, vacuum oil quenching furnaces, and carburizing furnaces. in vacuum.
Let's look at the uses of different types of vacuum ovens and the benefits of using a vacuum oven for parts processing!
1. Uses of Vacuum Brazing Furnaces
Vacuum brazing furnaces are mainly used for vacuum brazing of aluminum alloy heat exchangers and other aluminum products, brazing of stainless steel, titanium alloys, hard alloys, high temperature alloys, non-ferrous metals and vacuum quenching of high speed steel, mold steel, bearing steel, stainless steel, etc., as well as aging and annealing treatments of non-ferrous metals and vacuum brazing of stainless steel heat exchangers, engine oil coolers and cups stainless steel thermos.
2. Uses of Vacuum Gas Quenching Furnaces
Vacuum gas quenching furnaces are mainly used for high-pressure gas quenching of materials such as high-speed steel, tool steel, mold steel and structural alloy steel.
They can also be used for high temperature and solid solution brazing of stainless steel materials; sintering treatments and aging of powder materials, etc. It also has a rapid cooling function during annealing and solid solution.
3. Uses of Vacuum Sintering Furnaces
Vacuum sintering furnaces are used under hydrogen gas protection status after vacuum pumping, using the principle of medium frequency induction heating, causing the tungsten crucible in the coil to generate high temperatures, which are transmitted to the work by thermal radiation conduction, suitable for research and military units for sintering powder formation of refractory alloys, such as tungsten, molybdenum and their alloys. It is divided into horizontal vacuum sintering furnaces and vertical vacuum sintering furnaces.
The place where the electric furnace is installed must meet vacuum hygiene requirements, the surrounding air must be clean and dry, and there must be good ventilation conditions, and the workplace must not easily raise dust, etc.
Vacuum sintering furnaces are mainly used for the sintering process of semiconductor components and power rectifier components. They can perform vacuum sintering, gas shielded sintering and conventional sintering.
It is a new process equipment in the semiconductor equipment series. It has a new design concept, convenient operation and compact structure. It can complete multiple process flows on benchtop equipment. It can also be used for other vacuum heat treatments and vacuum brazing processes.
4. Uses of Vacuum Annealing Furnace
The vacuum annealing furnace is mainly used for deep drawing of stainless steel components such as hydraulic installations, ensuring that there is no oxidation.
Notably, the vacuum annealing furnace provides high productivity and a shiny, non-oxidized surface of the treated products. It is widely applied in fields including stainless steel bearings, cutting tools, self-tapping and self-drilling screws and stainless steel wire coils.
The furnace can also operate under a protective atmosphere, causing minimal pollution. The main function of vacuum is to serve as a barrier that prevents high-precision metal components from coming into contact with complex gaseous compositions under high temperature conditions, which can also be used for atmospheric annealing.
5. Uses of Vacuum Quenching Furnace
Vacuum quenching furnace is generally suitable for parts that require a bright and non-oxidized surface after tempering. It can be applied to high-temperature quenching of mold steel, high-temperature alloys, elastic alloys, copper alloys, titanium alloys, stress relieving and softening annealing of copper and copper alloys, while providing rapid cooling.
6. Uses of Vacuum Oil Quenching Furnace
Vacuum oil quenching furnace is suitable for vacuum heat treatment of mold steel, spring steel, stainless steel, bearing steel, high temperature alloy steel, and can also carry out annealing.
Its main advantages include a wide range of applicable materials, strong hardenability, low cost and reusable quenching oil.
However, it has the disadvantage of relatively greater deformation, requiring subsequent cleaning of the workpiece.
Structurally, vacuum oil quenching furnaces can be divided into two-chamber furnaces and three-chamber furnaces.
7. Uses of Vacuum Carburizing Furnace
The vacuum carburizing furnace can flexibly implement various heat treatment processes such as vacuum carburizing, vacuum carbonitriding, vacuum carburizing plus oil quenching, vacuum carburizing plus gas quenching and other functions of the vacuum furnace. It can be used to carry out relevant heat treatments on various materials and parts in the industrial field.
For example, carburizing and post-carburizing quenching of high alloy carburizing steels such as 12Cr2NI4A, 12CrNi3A, carburizing and post-carburizing quenching of structural steels such as 20CrMnTi, carburizing and post-carburizing quenching of stainless steels such as 1Cr13, and quenching and annealing of mold steels such as H13, W6Mo5Cr4V2, gear components, bushings, precision bearings, oil pump nozzles and precision mechanical parts.
With the increasing demand for heat treatment quality control in state-of-the-art equipment manufacturing and significant improvements in equipment levels, vacuum heat treatment is increasingly favored, and the industry's demand for high-end heat treatment equipment technology vacuum is growing year by year.
