Splashing in LD-KG-Converter

In this paper, variables effecting on splashing in LD-KG-converted are presented. The heat database was collected from one converter of Ruukki's Raahe Steel Works. Also the expert knowledge of personnel of the steel plant was utilized. Two dominant variables were found in this study, the batch size and added ferrosilicone in the early stages of the blow. By investigating more closely the heats, where the batch size and furthermore also ferrosilicone-addition were similar, it was possible to find some additional variables effecting on splashing. Some practical ideas were proposed to avoid strong splashing. Also most common variable combinations causing stronger or lower splashing are listed.
