| Principle |
|
The
controller calculates CP from input data from the Probe as well as
the programmable CO percentage in the furnace and controls the carburisation
process at the set values of CP . |
|
Control
Cycles
|
| Heating |
|
Process fluid (e.g. methanol ) started at operator set temperature
.Boost fluid (e.g. acetone ) switched on at a higher preset
temperature. |
| Carburisation
/ Boost |
|
The
system controls CP at the set value (high CP) by controlling the
boost fluid flow. |
| Diffusion |
|
At
the end of the carburisation cycle , the system automatically switches
the set point to the low CP value specified for diffusion ad controls
the process till the diffusion cycle is over. |
| Weight |
|
4
kg |
| Cooling |
|
The
process fluids are switched off at the preset temperature. |
