High Temperature Atmosphere Reaction and Heat Treatment Test to Support Evaluation of Catalysts

As a distinctive feature of this furnace, testing under a diverse range of atmospheres is possible.

Main features of multi-function heat treatment furnaces

• in addition to pure gases, Heat treatment testing is also possible under various mixed gas atmospheres.(Please inquire regarding available gas species and other test conditions.)
• Heating up to 1600℃ is possible; crucible melting is also available.
• Temperature variations are extremely slight, enabling stable heat treatment.
• Observation of the condition in the furnace during treatment is also possible.

Overview of multi-function heat treatment furnace

• Available atmospheres

  • Air, nitrogen (N₂), argon (Ar), carbon monoxide(Co), ammonia (NH₃), hydrogen gas (H₂), vacuum (basic specifications).
  • Can also respond to a diverse range of other requirements, including inert, reducing, and oxidizing atmospheres, etc.

• Large capacity

  • Effective volume of heated part: 250 mm × 250 mm × 250 mm
    (Treatment of A4 size and other large-scale specimens and parts is also possible.)

• High temperature

  • Max. temperature: 1600℃
  • High temperature treatment (melting) of ferrous, nonferrous, and other materials is possible.
  • Addition/sampling during treatment is possible by using the furnace-top opening.

• Inside observation during treatment

  • Furnace has sight glasses on the top and side, enabling observation of the condition in the furnace during treatment.

Example of heat treatment test

Heat Treatment Testing of Various Materials/Parts

As a distinctive feature of this furnace, testing under a diverse range of atmospheres is possible. Taking advantage of this feature, heat treatment testing can be performed under a wide range conditions.

• Example of test condition

  Atmosphere	Temparature	Material
  N2 atmosphere	800℃	metal plates
  H2 atmosphere	1100℃	metal parts
  N2 + CO2 + water vapor mixed gas	1000℃	steel

  Actual examples

  • Steam oxidation test of steel
  • Reduction test of oxide powder
  • Decarburization test of steel
  • Heat treatment test of metal plates, etc.

• 

Measurement of High Temperature Behavior

• • Measurement and observation of high temperature deformation, reaction, and melting behavior, etc. is possible by using the furnace observation windows.
    When placed in a high temperature atmosphere, materials undergo various types of deformation, such as swelling, softening, melting, etc. The material shape also changes as a result of reaction with the atmosphere gas (e.g., oxidation, carburization, nitriding, etc.).
    When placed in contact with a different material, phenomena such as bonding, reaction, sintering, etc. may also occur between the two materials.
  • Using JFE-TEC's facilities, it is possible to reproduce actual service conditions (atmosphere, temperature) and investigate material deformation and the progress of reaction behavior.

• 

Measurement and visual observation of dimensional and weight changes are also possible.

• 

• In addition to the heat treatment furnace described above, JFE-TEC also has a tube furnace which can be selected depending on the purpose of testing. This facility enables not only comparison of the specimen appearance, dimensions, and weight before/after high temperature treatment, but also measurement of dimensional and weight changes during the high temperature test.
