Computer Control of LD Converter Process of Steelmaking

An LD converter can produce 200- 400 tons of steel in 20- 25 minutes. However, the fast dynamics of the process makes accurate manual control very difficult and necessitates computer control. In this report, first a study of LD process dynamics has been presented; the influences of various inputs, disturbances and control variables on control
