Important Basis

The solidification shrinkage of liquid steel has an important impact on thermal deformation behavior of high-temperature thin shell. Solidification shrinkage of liquid steel is an important basis for structure and shap optimization of the mould. In this paper, a direct coupled model was built on heat transfer in solidification and stress-strain by using the ANSYS software. And solidification shrinkage of liquid steel with the interior temperature and stress distribution were studied in the process of steel solidification, and it provided a theoretical basis for the further optimization of shape of the thin slab FTSC mould. This study was based on analysis of temperature and stress, deriving calculation of solidification shrinkage of steel’s phase change on macro-state by calculating the variation discipline of the distance between nodes.

This paper discusses a non-destructive measurement technique of residual stress through optical visualization. The least amount of deformation possible is applied to steel plates by heating the specimens +10 °C from room temperature for initial calibration, and the thermal expansion behavior is visualized with an electronic speckle pattern interferometer sensitive to two dimensional in-plane displacement. Displacement distribution with the thermal deformation and coefficient of thermal expansion are obtained through interferometric fringe analysis. The results suggest the change in the thermal deformation behavior is affected by the external stress initially applied to the steel specimen. Additionally, dissimilar joints of steel and cemented carbide plates are prepared by butt-brazing. The residual stress is estimated based on the stress dependence of thermal expansion coefficient.
