M/s Sunflag Iron & Steel Co. Ltd., have a unit of DRI Plant having a rated capacity of 150,000 TPA built with overseas technology. However, the plant operation could not be optimised over a long period. In 1991 Sunflag approached OSIL to assist in optimising their operation. OSIL studied their plant parameters, identified the points of non-compatibility and recommended modifications with engineering support. The major modifications suggested are : 

- Controlled Raw Material Sizing

- Coal Slinger System (Coal Injection)

- Kiln Operation – Logic

- Kiln Discharge System 

- Improvement in air sealing system and prevention of air leakage

- Modification in kiln to cooling drum transition chute to ensure free-flow of kiln-discharge


Within six months of OSIL's association the plant performance improved to a great extent.
