Research & Development

To Stretch the Raw Materials Envelope

This programme was taken up to improve the process of lowering the phosphorus content in the converter during oxygen steel making. Themes addressed are design of a new supersonic lance, improvement in bottom stirring and assessment of the BOF slag system.

• Trials have been carried out at the LD2 steel plant in Jamshedpur with a new 6+1 hole top lance designed by R&D.
• Implementation of a new way of blowing argon from the vessel bottom called ‘Differential Flow’ at the LD2 plant in Jamshedpur has improved the phosphorus partition and reduced the argon consumption.
