Description

technical field [0001] The invention relates to a twin-roll strip continuous casting solidification simulation device and method. Background technique [0002] In the twin-roll strip continuous casting process, the molten steel in the molten pool composed of two crystallization rolls and side sealing plates contacts the crystallization rolls, and quickly solidifies to form a solidified shell in a very short period of time. Finally, the cast strip is formed, and then the cast strip is rolled in-line, forced cooling and coiled to form the finished coil. In the whole process, the sub-rapid solidification process of molten steel on the surface of the crystallization roller is the core of the whole process, which directly affects the production stability and the quality of cast strip products. Therefore, research on the sub-rapid solidification process of molten steel on the surface of crystallization rolls has been continuously implemented through various simulation experiments...
