Abstract

Jindal Steel Works (JSW) in Toranagallu, India, focuses on steelmaking technologies to be able to utilise iron ores of varying grades for the production of high quality steel grades. In the converters, for example, bottom gas purging is applied together with slag splashing maintenance technology in order to achieve the required high quality of tapped steel with minimum conversion costs. To meet this target a partnership between JSW and RHI was successfully created comprising an implementation team from JSW and a continuous site supervision from RHI. The realized metallurgical and process benefits due to gas purging in combination with intensive slag splashing maintenance of the converter are described below.
