Les exigences de la fonte et de l'analyse des métaux précieux ainsi que les applications sidérurgiques et métallurgiques nécessitent des fours spécialement conçus. Carbolite Gero propose des produits dédiés pour répondre à ces exigences spécifiques.
The HRF furnace is suitable for hardening and tempering steel by increasing the mechanical resistance through heat treatment. Powerful recirculating air turbines ensure excellent temperature homogeneity for optimum heat distribution, this complying with requirements according to AMS 2750G Nadcap.
For typical soft annealing temperatures under vacuum up to 750°C and inert or reactive gas up to 1100°C, the annealing furnace range GLO is recommended. This helps to reduce precipitations in the steel to decrease the strength and hardness of the material and increase the plasticity to facilitate further process steps. The additional quick cooling option offers the possibility to precisely maintain materialspecific temperature profiles, thus ensuring high product quality.
For the production and processing of special steels and steel alloys, different types of heat treatment are required. The HTK chamber furnace series offers a variety of solutions in terms of size, temperature range and gas packages.
The furnaces can be operated up to a maximum temperature of 2200°C; the HTKW/22 model, for example, is suitable for operation in ultrahigh vacuum, under hydrogen partial pressure or with other reactive gases. It is also possible to carry out surface hardening by nitriding or carburization in a nitrogen-rich (ammonia) or carbon-rich atmosphere with slight overpressure at which nitrogen or carbon diffuses into the steel.
The maximum temperature for carburizing is 3000°C in a HTK GR/30. Data recording is possible for all furnaces, ensuring compliance with and monitoring of quality standards in process operation.
