| Abstract Scope |
The green and cycle and sustainable development of the steel industry represents the future direction. The continuous increase in scrap steel production capacity has led to an increase in the content of impurity elements in molten steel. Twin-roll strip casting can effectively suppress the segregation of impurity elements. Therefore, it is of great significance to study the migration behavior of different impurity elements during twin-roll strip casting. In this study, elements Al, O, N, and Ti were used as variables, and the sub-rapid droplet solidification technique was employed to simulate the solidification process of twin-roll strip casting. The effects of impurity elements on the deposition film, heat flux, and wettability were investigated. The mechanism of deposition film was elucidated through SEM-EDS analysis and thermodynamic calculations. The results show that the impurity elements reduce the heat transfer and wettability by forming deposition films with different compositions and thicknesses. |
