Improvement of the BOF process by use of a radar measurement at the Dillinger Hütte
2001
In order to achieve comparatively constant BOF process data, a radar measurement equipment was installed at the two 185-t vessels at the Dillinger Hutte steelplant. The level of liquid steel in the converter is easily measured for every heat with a radar unit. With this installation, the distance between the tip of the oxygen blowing lance and the steel surface can be adjusted in accordance to process conditions. As a result, metallurgical and technological improvements were achieved, e.g. the Fe-content of the slag was reduced and the lime consumption could be lowered as well. A more uniform lining wear can be observed and the life of lance tips is increased.
