摘　　要：桥梁支座板是一种要求很高的平板类铸件,其连接桥梁上部和下部,是桥梁的重要传力装置。根据结构特点及技术要求,设计冒口及浇注系统,确保补缩和平稳浇注,保证其内部组织致密、无缺陷,并通过CAE凝固过程模拟分析、流场分析验证。通过控制主要化学成分、微合金化、优化热处理工艺等,保证其机械性能尤其是低温冲击性能符合要求。Bridge bearing plate is a kind of plate casting with high requirements. It connects the upper and lower part of the bridge and is an important force transmission device of the bridge. According to the structural characteristics and technical requirements,the design of riser and pouring system,to ensure feeding and stable pouring,to ensure that its internal structure is dense,without defects,and through CAE solidification process simulation analysis,flow field analysis verification. By controlling the main chemical composition,microalloying and optimizing the heat treatment process,the echanical properties are guaranteed to meet the requirements,especially the low temperature impact properties.
