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.
