1 Cold rolling tandem mill
“azbil” Solutions for Steel Plant Iron ore Pellet Limestone Coke Sintered ore Blast furnace (BF) Hot metal Basic oxygen furnace (BOF) Scrap Iron making Electric arc furnace (EAF) Steel making Continuous 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 Main products Plate mill Plate Wire rod mill Wire rod Section mill Bar Shape Sheet pile Rail Integrated Open DCS Field Instrument & Control Valves

2 ALARM(Leakage detected)
A Suggestion at Tuyere of Blast Furnace Blast Furnace Arithmetic and Control Unit(DCS or Sequencer ) A Entrance(Cooling water) B Exit(Cooling water) 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! Damaged pipe, Cooling water leakage ⇒Steam Explosion Most Important Monitor Point

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<3 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<5 L/min Differential flow rate: below than 1.0% of full scale *) Accuracy of Electro-magnet Flow meter: ±0.5% of reading

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

5 azbil Open System Platform with a variety of Solution Packages
Yamatake Solution Vision with System Platform PM-EX PM100 AMC Knowledge Power Alarm Analyst PREXION, MIB Electric Shift Log Utility Optimization 3rd party system Integrated HMI DOPC DGFC DGPL Field Client PlantWalker-HV Ex Proof Field Client OperationAnywhere

6 Distill data in multiple sources into useful data
MIB- For Manufacturing data visualization Personalized window presentation images… For Manufacturing Manager For Manufacturing Stuff For Shift Leader Distill data in multiple sources into useful data Personalize useful data for each individual meeting their role and responsibility SOP Shift Log Batch History Plan/Performance Order/Ship Quality Labo Asset Data

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

8 Alarm Analyst - Correlation analysis
Alarm Analyst R20 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.
