摘要
为在满足热轧带钢精轧前的温度要求的同时提升轧制效率,该文针对传统空冷方式降温慢、影响产线节奏的问题,设计一种粗轧后带钢射流冷却系统。首先,建立控温冷却系统的结构模型,分析其主要部件的作用与功能;随后对喷嘴结构参数进行优化设计,选定合适型号并构建三维模型;最后使用有限元分析软件ANSYS Fluent进行流体力学仿真,获得带钢在喷淋冷却过程中的温度分布和流场特性。结果表明模拟数值与实测数据的温度误差在15 K以内,证明所提模型为冷却系统改造提供具体参数依据,可以直接用于现场喷嘴布置优化,提升热轧产线的节奏与产量。
In order to meet the temperature requirements of hot rolled strip before finishing rolling while improving rolling efficiency,a jet cooling system for strip after rough rolling is designed to solve the problem of slow cooling by traditional air cooling method and affecting the rhythm of the production line.First,a structural model of the temperature-controlled cooling system is established,and the functions and functions of its main components are analyzed;then the structural parameters of the nozzle are optimized,the appropriate model is selected,and a three-dimensional model is constructed;finally,the finite element analysis software ANSYS Fluent performs fluid dynamics simulation to obtain the temperature distribution and flow field characteristics of the strip during spray cooling.The results show that the temperature error between the simulated values and the measured data is within 15 K,which proves that the proposed model provides specific parameter basis for the transformation of the cooling system,and can be directly used for on-site nozzle layout optimization to improve the rhythm and output of the hot rolling production line.
