Linz-Donawitz converter

LD converter steelmaking is a complex physico-chemical process where many variables have effects on thequality of the resulted steel. The main features of the process are the followings: a large (~150-ton) converter is filled with waste iron, melted pig iron and many additives, then it is blasted through with pure oxygen to burn out the unwanted contamination (e.g. silicon, etc.).

This article summarizes the outcome of research work carried out to improve the performance of the oxygen lance in the LD steelmaking process. In order to augment the droplet generation, a new oxygen lance with a central subsonic nozzle through which flow can be controlled has been introduced and its blowing performances studied using numerical and water model studies.
