The technical design of the chamber furnace sealed quench CASEMASTER® type, introduced to the market by ELTERMA S.A. provides:
- automation of the heat treatment and heat-chemical treatment processes
- repeatability of the processes
- elimination of skin decarburization of the workload surfaces after heat treatment and heat-chemical treatment processes.
Chamber furnace with integral quenching tank CASEMASTER® is available in the following versions:
- Single door and pass-trough furnaces
- One and two-chamber furnaces
- Electrical furnace and gas fired furnace.
For the controlling of operation of the CASEMASTER® furnaces and technological lines based on them, the computer system is used which, besides its standard functionality in the heat treatment additionally realize following tasks:
– Calculation of the carbon diffusion in carburizing process in „on-line” mode
– Calculation of parameters of furnace atmosphere on the mathematical model of the chamber of the furnace
- Function of technological diagrams (current profile of concentration of carbon, expected hardness profile after hardening, current state of the process on the diagram iron - carbon and iron oxidation)
- Programming overhaul.

The same construction philosophy characterises various types of plants built by CIEFFE FORNI INDUSTRIALI, applying the maximum automation where possible,
Some examples of this kind of custom-built plants are:
- automatic belt lines for the hardening and tempering of self-tempering stainless steels;
- automatic lines for die quenching furnaces with roller movement;
- automatic roller-, pusher-, chamber-lines for isothermic hardening and tempering;
- automatic treatment lines for aluminium parts;
- automatic high productivity lines for the annealing of noble metals;
- automatic lines combined with continuous and discontinuous plants with the same store and the same loading dimensions.
As to this regard, we would like to draw your attention to the considerable gain of flexibility in the management of the charges in system like this, where the same priority, according to production and quality requirements, can be directed to two different working areas of the same store.
The construction of plants working in controlled atmosphere obliges us to the continuous research of new systems for the generation of atmosphere for the various types of treatments. The current research regards the reduction of expenses and the reaching of the quality standards demanded by the market.

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.
