Hi Gurudas ,
Typically In gas carburizing, steel is heated above the austenitizing temperature in a gaseous atmosphere capable of providing carbon to the surface of the part. If the atmosphere's carbon potential is higher than that of the steel, carbon from the atmosphere will diffuse into the steel, developing a carbon-rich case of higher hardenability than the base metal .
The whole process go through the process of heat treating from the entrance to the exit covering the degreasing, preheating, carburizing, diffusion, cooling, hardening, post-washing and tempering
For applications like these where you need precise control of your temperature and also acquire signals from oxygen probes the solutions can be confined to two platforms from National Instruments
:
1) PXI RT
2) FieldPoint RT
Some of the signals like the t/c would need signal conditioning and so a combination chassis on PXI with suitable signalconditioners ona Realtime Controller would give maximum determinism to your application
trnsforming to maximum reliability , accuracy of the control that you need to do .
The RealTime (RT) Environment has a Host Computer where you can load LabVIEW RT and through Ethernet download the application to a Target environment like PXI or Fieldpoint , where the controller has a RTOS which runs the LabVIEw code .
Once you download the application , the PXI system runs independently intelligently even if the communication between the host desktop computer is lost .
The advantage that you get is that you have a open platfrom like PXI , where you can control the technology .
Gurudas, if you need more information on the system configuration and want to know more about this RT system , talk to me at ranjit_nambiar@hotmail.com or
