Speech Title: 

Research on thermal and mechanical behavior of continuous casting mold

连铸结晶器的传热与力学行为研究


Abstract: 

During the continuous casting process, the solidification of slab always deviates from ideal state, the non-uniform heat transfer, deformation and friction have been the major reason of slab defects, which becomes the key factor to improve slab quality. Rationally connect numeral simulation and measured data to investigate the asymmetric and non-uniform character during mold, and discuss the key factors which would affect the slab quality such as heat transfer/solidification, stress/deformation, friction/lubrication and gap distribution under real conditions, is one of the key point of the research. Based on this, this paper focuses on the heat transfer, solidification, deformation and friction in continuous casting mold and slab, and it is significant for improving slab quality and optimizing process parameters.

连铸生产过程中,铸坯的凝固进程往往偏离理想状况,结晶器内非均匀的传热、变形和摩擦是诱发铸坯表面缺陷的主要根源,成为稳定和提高连铸坯质量的瓶颈性因素。其中,合理衔接数值模拟与浇铸过程实测数据,以考察结晶器复杂冶金过程的非对称、非均匀特性,进一步探讨真实工况下铸坯与结晶器的传热/凝固、应力/变形、摩擦/润滑和气隙分布等影响连铸坯质量的重要因素,是研究工作的重点之一。有鉴于此,本研究将实测数据与数值模拟相结合,重点围绕连铸板坯-结晶器传热、凝固、变形和摩擦行为进行研究,研究结果对于铸坯质量提升和连铸工艺优化具有重要意义。
