Changes in morphology of inclusions in steel under the top slag without calcium
Original language description
Many authors dealt with change of the chemical composition of inclusions after dosage of calcium by cored wire or through the top lance. This paper aims to focus on the issue, whether inclusions in steel change their morphology without addition of calcium. Evolution of inclusions under top slag is monitored in conditions of atmospheric pressure and vacuum. Change of the chemical composition of inclusions during processing is discussed and then a mechanism for the conversion of inclusions during processing is proposed. For this purpose samples from steel and slag were taken at different treatment periods. The steel samples were subjected to chemical and metallographic analysis of inclusions. The slag samples were subjected to chemical analysis. All theheats were prepared by this production process: OBM converter - ladle furnace ? vacuum chamber ? continuous casting.
