26 Ironmaking Steelmaking Energy & Environment Since 1977 Level 2 SDM

27 Level 2 system The Level-2 software contains two main components: The process model (SDM) The environmental shell Model SDM stands for Static and Dynamic model and serves all the processes in a BOF shop.

28 Level 2 system Environmental Shell Maintaining default process schemes & SOP s Interaction with Level 1 (collecting data and set points transmission) WGA and ASCON interaction Interaction with L3, other L2 systems and lab Data management Reports SDM process model Process aim calculation Ordering calculation Desulphurisation Blowing calculation Dynamic control calculation Ladle alloying calculation Feedback calculation

29 SDM Benefits The use of SDM brings the following advantages: Improvement of process efficiency Higher accuracy of end-point temperature Higher accuracy of end-point carbon content Reducing the number of re-blows Decrease Fe-content in the slag Increase converter lining life Optimise scrap melting efficiency.

30 Ironmaking Steelmaking Energy & Environment Since 1977 Sublance Probes

31 Sublance Probe

32 Available Sublance probes TSC (Temperature, Sample, Carbon content determination) used for measurements during oxygen blowing TSO (Temperature, Sample, Oxygen activity) used for measurement after the blow plus bath level determination P probe T (Temperature) Used (rarely) for measurement after the blow
