| 摘 要： | 为了提高宽幅冷轧薄板板形尤其是边中复合浪等高次复杂浪形的控制能力,研究工作辊精细冷却喷射梁的结构参数及其安装尺寸对精细冷却效果的影响.采用流体建模软件ANSYS Fluent建立工作辊精细冷却的三维VOF非稳态模型,分析精细冷却喷嘴孔口特征比、喷嘴到工作辊距离和喷嘴之间的距离对工作辊冷却效果的影响.仿真结果表明:喷嘴孔口特征比较小时,射流轴线速度衰减慢；利用射流在特征衰减区的特性合理控制冷却喷射粱喷嘴与工作辊之间的距离可提高精细冷却效率；喷嘴间距适度减小可使控制区域的工作辊温度场冷却效果更均匀并提高精细冷却效率.

| Abstract: | In order to enhance the controllability of profile and flatness for ultra-wide cold-rolled strip,especially the complex waves such as the center buckle with edge wave,the effect of the structural parameters and assembly dimensions of spray header of multi-zone cooling on the coefficient of heat transfer and the temperature distribution of work rolls was studied.The 3-Dimensional unsteady VOF models were built up by ANSYS Fluent flow modeling software to simulate and analyze the multi-zone cooling performanc... |
