Abstract:

As an important integrated casting-rolling short-process technology in the field of materials and metallurgy, twin-roll strip casting has significant application value in the preparation of thin-gauge strip steel, special steels, and special alloys. Addressing the complex theoretical and technical challenges of multi-element, multi-phase, multi-variable, and strongly coupled high-temperature melt flow and heat transfer during the twin-roll strip casting process, this paper reviews the research progress on key technologies, process control strategies, and product-related technologies. Based on theoretical research and technological development practices, it highlights the independent innovative achievements and technical applications in high-temperature melt distribution, casting roller cooling, side sealing technology, and casting-rolling process control. Finally, it points out the theoretical and technical issues that require further study to promote the application of this technology in the research and production of high-end, high-quality steel materials.

Key words: steel, twin-roll strip casting, process technology, control strategy, product technology
