Transcript

  • 1. Innovation Storyboard [EMIRATES ALUMINIUMCOMPANY LTD ][CRUSHED BATH AND SILO –PTM SIMULTANEOUS FILLING ] [ SID 1798] [Reduction R1]
  • 2. 1. About the Organization• Emal is one of the world’s largest green field smelter• Emal aims at high quality delivery of its products to customers, safety, every thing can be improved• Aluminium ingots, sow, slabs• Taweelah
  • 3. 2. The IdeaCrushed Bath Silo Filling and PTM Filling Simultaneous Operation
  • 4. PROBLEM• Average no. of PTM’s to be filled during anode setting per shift is 7 nos.• PTM Bin capacity is 5m3• Shift Requirement= 7x4x5m3= 140m3• Daily Consumption= 140x3= 420m3• PTM Filling Station Silo capacity is 70mt• Pot-line operations raised their concern regarding delays in withdrawing ACRM material which consequently causes delays in their day-to-day activities. The projected idle time for two cell operator is 90 mins. Scheduled jobs will be disrupted and may incur overtime. Environmental concerns are also highlighted due to prolong open pot shields scenario during anode setting.
  • 5. 3. People Involvement• SIMULTANESOUS SILO- PTM FILLING• REDUCTION• SID:• Suggestors : Suresh Basappa• Deepu Ramachandran• Rajesh Chenolil• Supervisor :Rafel panga
  • 6. 4. Process
  • 7. Process• Implementing the logic changes in the programme to enable the simultaneous filling of the silo and the PTM
  • 8. Process• Refilling request commences when the silo level falls below 50%• Refilling time varies depending on the physical location of the ACRM Day Silo.• Since it is a batch conveying system, each refilling is approximately 5m3 which is capable to fill 1 PTM.• System is limited 2 PTM fillings between two consecutive silo filling.• At present the we have only two Pressure Vessels that are extensively used in the ACRM transport system. On a 24-hour operation each vessel approximately conveys 40 cycles per day.• The priority is set which ever comes first, meaning, if silo refilling is engaged PTM filling is not possible and if PTM filling is engaged silo refilling is not possible.• The present logic also inhibits the PTM filling if in case the required silo level is not reached with one refilling sequence alone.
  • 9. 6. Learning• Installed in all the 8 Stations successfully• No repetition of the problem till date• Simple solutions have tremendous effect on the system• Simple solutions yields enormous results
  • 10. 7. Way Forward• All the team members were awarded .• Applied in the design of future pots for further expansion of Emal .• Motivated in providing many more innovative suggestions
  • 11. Q&A
  • 12. Thank You
