中文摘要： 连铸坯与结晶器铜板的粘结是制约高拉速连铸和宽厚板连铸技术发展的关键因素之一，预防和监控粘结对保证连铸生产顺行、生产高质量铸坯和优化连铸工艺具有重要意义。本项目拟开展以铸坯粘结行为为主线的系统研究，从连铸基础理论出发，结合凝固坯壳的力学行为等方面，构建粘结形成、传播和修复模型，并基于粘结实例的实测数据进行验证和优化；试图从联合在线实测和粘结模型的双重角度对粘结行为进行完整表述和准确解析，揭示粘结形成、传播和修复机制，厘清并量化影响粘结行为的主要因素和作用规律；以此为基础，确立粘结产生的判据和预测方法，完善粘结传播行为的判定方法，提出动态粘结报警控制策略，最终形成可操作性强、完整有效的粘结防控方法体系。研究结果将进一步深化对铸坯粘结形成、传播和修复行为的认识，为结晶器冶金过程的科学调控提供理论基础和技术支撑。

英文摘要： Sticker between continuous casting slab and mould is one of the key factors which restrict the development of high speed continuous casting and wide and heavy plate continuous casting technology. Prevention, monitoring and control of the sticker are of great significance for ensuring smooth production and high quality slabs, optimizing continuous casting process. In this project, slab sticker behavior will be systematically studied as the main line. Firstly, based on basic theory of continuous casting, sticker formation, propagation and recovery models are established by combining with mechanical behavior of solidified shell, etc. And the models are verified and optimized by measured data of many stickers. It tries to make complete description and accurate parsing for sticker behavior from the double angles of online measurement and sticker’s models, and to reveal sticker formation, propagation and recovery mechanisms, and further to clarify and quantify the main factors influencing sticker behavior and law of action. On this basis, the criterion and prediction method of sticker formation are established, and the judgment method of sticker propagation behavior is improved, and dynamic sticking alarm control strategy is put forward. Finally, a complete and effective prevention and control method system with strong operability is formed. The results of this study will further deepen the understanding on formation, propagation and recovery behavior of slab sticker, which can provide theoretical basis and technical support for scientific regulation of mould metallurgical process.
