Understand Atmosphere In Carburizing Applications Using Simulation and Real-Time Carbon Diffusion

In gas carburizing the source of carbon is a carbon-rich furnace atmosphere produced either from gaseous hydrocarbons or from vaporized hydrocarbon liquids.  Using theoretical steps with anticipated process variable inputs, the prediction of the carbon available to the steel surface and diffusion can be simulated.  Inputs captured during a real-time run can predict the carbon build up in a part.  The simulation and real-time data can be matched up to compare metallurgical results. 

We will cover principles of atmosphere carburizing including sensor and control technology.  Analysis of input variables associated with carburizing applications and understanding the effects the atmosphere, temperature and time has on results.  We will look at information using 3-gas analysis versus oxygen probes and review what an atmosphere would look like during a carburizing run.  We will review real world scenarios with actual data that compares simulation versus calculated carbon transfer and diffusion against met lab results.
