Industrial tempering vacuum furnace
Type: B5_R
B5_R, vacuum furnace for tempering, annealing and nitriding (option) options
form for inquiry
  • BMI vacuum furnace for the main low-temperature vacuum heat treatments: tempering, annealing, ageing, stress relief, etc.
  • B5_R is a vacuum furnace which offers both excellent homogeneity of temperature and short cycle times while respecting the integrity of the surfaces of the parts to be treated.
  • This BMI furnace has a low dead load and is very well insulated, thus significantly reducing energy consumption and so treatment costs.
  • This compact furnace is of robust construction, thus reducing maintenance costs.
  • As an option, the vacuum furnaces of the B5_R family can be equipped with ALLNIT® low pressure nitriding which can also be complemented by ALLNIT-OX® post-oxidation. These furnaces are called B5_RN.
  • The *COOL PLUS* cryogenic process, developed and patented by our sister company, SCHMETZ, is available as an option on the B5_R. This cold treatment is performed at the end of the quenching cycle and offers several advantages: *COOL PLUS* reduces the level of residual austenite while increasing the hardness and dimensional stability of the treated parts. Moreover, the parts maintain an exceptional shine because of the total absence of condensation after the change to cold. This "sub-zero" treatment process, particularly suitable for treating stainless steels, high-speed steels and tooling, is performed between the quenching and tempering cycles.
