Abstract

The selection of charge materials, lance operation, lance tip design and bottom stirring are the important criteria by means of which the LD-process can be monitored and controlled. This paper demonstrates the effects of the individual components on the process as a whole, and shows the mutual influences and dependencies of the factors discussed. The aim of the present discussion is to explain the processes taking place in the LD-converter and to suggest ways of improving the processes where problems arise.
