1 1 Iron ore Pellet Limestone Coke Sintered ore Blast furnace (BF) Hot metal Basic oxygen furnace (BOF) Scrap Iron making Electric arc furnace (EAF) Steel makingContinuous casting Hot direct rolling (HDR) Billet Bloom Slab Reheating furnace Steel casting Rolling Seamless pipe mill Seamless pip Welded pipe mill Welded pipe Butt welded pipe Cold rolling tandem mill Cold rolled coil and sheet (also for plating) Hot strip mill Hot rolled coil and sheet Main products Plate mill Plate Wire rod mill Wire rod Section mill Bar Shape Sheet pile Rail azbil Solutions for Steel Plant Integrated Open DCS Field Instrument & Control Valves

2 2 A Blast Furnace B Entrance Cooling water Exit Cooling water Arithmetic and Control Unit DCS or Sequencer Damaged pipe, Cooling water leakage Steam Explosion Most Important Monitor Point ALARM Leakage detected) A B Flow rate difference) Target Normal A B Flow rate difference) Target Abnormal High accuracy complies with reliable monitoring on cooling water leakage at tuyere! A Suggestion at Tuyere of Blast Furnace

3 3 Differential Flow Rate Strict Monitoring Standard Since cooling water leakage is very important factor to monitor, very small leakage must strictly be measured. A company in Japan Flow rate range: L/min Targeted differential flow rate: A B L/min Differential flow rate: Below than 0.375% of full scale B company in Korea Flow rate range: L/min Targeted differential flow rate: A B L/min Differential flow rate: below than 1.0% of full scale *) Accuracy of Electro-magnet Flow meter: ±0.5% of reading

4 4 Differential Flow Rate Monitoring Field Trial A Company – Result of Field Trial Targeted Differential Flow Rate: 0.375% of F.S. Result: 0.275%FS: Fully complied with severe monitoring standard! A (Entrance) B Exit A-B Differntia lFlow rate

7 7 Infrastructure of production Information system Process historical information user can utilize the information at any time and any accuracy depending on their work. Technology Control Quality Control Facility Management Production Control Operation Manageme nt Site performance for Plant Manager Production performance for Production Engineer Process performance for Shift Leader PREXION – For production monitoring

8 8 Alarm Analyst - Correlation analysis Correlation Analysis;- Easy to build Knowledge-Base alarm & event model… unique technology From alarm & event historical logs, Correlation Analysis extracts ;- Event groups consisted of the alarms and the operation actions in a process upset Propagation path Source origin Nuisance alarms Total counts in Alarm & Event group Information about Alarm & Event group structure Cause & Effect relationship –Cause of alarm flood or complex operation is estimated using order of events occurrence.
