Treatment Supervision
During treatment of a heat at the RH station, the heat status is tracked according to signals of Level 1 or manual inputs. Based on this tracking the respective model calculations are started and the operator is guided through the treatment process.
Following treatment steps are distinguished:
Waiting – heat has been logged in and has arrived in the treatment position (signal from Level 1)
Recirculation/ Stabilization – ends with signal from Level 1, when operator confirms stabilization
Natural and Forced Decarburization – ends when calculated C-concentration is below its aim or decarburization time is longer than a minute time from the practice data,
or the operator finishes decarburization by manual input, in order to get an earlier start of the subsequent process steps.
Dehydrogenation – ends when calculated H-concentration is below its aim or dehydrogenation time is longer than a minute time from the practice data,
or process step of leaving has started.
Process Step Trimming
During this step different material addition is done. Material addition may be finished prematurely by operator's manual input.
Before any material addition the corresponding model is started. For detailed description see chapter Process Models.

Treatment End
At treatment end, indicated by the operator or by the corresponding Level 1 signal, the system checks the actual condition of the steel bath (analysis and temperature). If the chemical analysis is out of the allowed range, some additional treatment is necessary. In this case the operator is advised to start the required action.
If no more remaining activities are detected, the operator has to finish the ***refining*** using the treatment end dialog. Missing information concerning the heat can be entered.
