Analysis and industrial application of the soft reduction model in continuous bloom casting of C92D2 steel
School of Materials Science and Engineering, Jiujiang University, 332005 Jiujiang, China
Soft reduction is a key method to reduce or eliminate the internal quality defects of high carbon steel in blooming castings. In the present work, the total reduction amount and the distribution of the reduction amount at various casting speeds were calculated using the obtained model of the soft reduction amount. Industry experiments were carried out on soft reduction in continuous casting to improve the internal quality of C92D2 high carbon steel blooms by means of the model. The results show a remarkable improvement of the internal quality of C92D2 high carbon steel blooms by applying a suitable reduction mode during continuous casting.
