CAE 해석을 활용한 대형 중공 잉곳 제조 연구

다국어 초록 (Multilingual Abstract)

The solidification patterns and internal microstructures of hollow ingot are investigated at various ingot casting experiments, using an optical microscopy and a computer simulation analysis. An ingot shape and casting conditions of very large hollow ingot with about 37ton weight are obtained throughout a computer simulation analysis using these experimental data. To verify these predicted data, a large hollow ingot of 37ton grade is manufactured, and then examined its internal qualities such as segregation grade and solidification pattern. It is found that these experimental results are well agreed with the predicted ones by a computer simulation. It is observed that the hollow ingot has less segregation band and low hot-top shrinkage than those of conventional ingot. Especially, the solidification defects are not observed in the hollow ingot.
