Evacuable chamber tempering furnaces, series RH…RVe/g, are mainly used to temper and anneal materials treated in vacuum hardening furnaces. The RH...RVe type furnaces are electrically-heated, whereas the abbreviation “g” is used for gas-heated models.
The systems consist of a furnace body with modern, low heat-retaining insulation and the horizontal sliding retort with a gas circulation unit.
The integrated indirect cooling system permits cooling under a protective atmosphere (inert gas). The pump stand consists of a mechanical vacuum pump with the associated measuring instruments.
The switchgear is equipped with a freely-programmable process control system. The selection of this equipment permits very flexible process design.
The IVANIT unit permits nitriding, nitrocarburizing and oxidizing in evacuable tempering furnaces.
Moreover, the furnaces can be equipped with a specially developed rapid cooling system on request. This system achieves direct cooling of the nitrogen atmosphere, radically reduces the cycle times and thus renders IVA chamber tempering furnaces even more economical.
In combination with IVA vacuum chamber ovens, series VH...U/K, these evacuable tempering furnaces offer an attractive package for hardening and tempering of tools made of hot-work, cold-work and high speed steel.
