Processes:
Carbonitriding
Annealing
Gas carburising
Hardening
High/low tempering
Nominal temperature: up to 1000oC
Max load weight: from 180 kg to 1500 kg
Useful space dimensions: from 450 x 300 x 650mm to 760 x 910 x 1800mm
The advantages of the CASEMASTER® furnaces are:
Low voltage tubular heating elements, typically heating element life in excess of 30,000 hours in carburizing furnaces
Temperature uniformity +/- 5oC, optionally with multi-zone temperature control
Robust construction and close control of the carburizing atmosphere and heating systems helps to give the furnace a long operational life,
Atmosphere circulating fans have profiled blades to ensure high mixing and circulation capacity
Furnace construction and operation eliminates any potential oxidation of the workload surface after carburizing process. |

Equipment: loading system, vibrators, washing machines, oil separators, salt recovery system and tempering furnaces...
Technical and economical advantages :
Choice of the heating mode (Gas or electric).
Choice of the quenching media, the extraction mode as well as the washing system upstream and downstream from the furnace.
Homogeneity of treatment and reproducibility of the results.
Reduced production costs and times.
Economy of energy thanks to the rapid treatments series changes and to the fast setting in production.
Reliability and longevity of the elements thanks to their design and to the used materials |

Design Features:
- Electric or gas heating.
- Gas-tight alloy muffle, for perfect furnace atmosphere control and low protective gas consumption.
- Choice of protective gas systems, for external supply or built-in generator, to suit all industrial requirements.
- Unique SAFED mesh belt drive system, with reciprocating hearth plate, for smooth parts transport and low belt wear.
- Automatic control of all process parameters, for versatility and reproducibility..
Operation:
Workpieces are loaded in bulk or positioned on the mesh belt at the loading station. They pass through several heating zones inside the gas-tight muffle to the chute and drop into the quench. The workpieces are then retrieved from the quench tank by a conveyor. |
