摘要
基于洛阳某铝厂设计的气垫炉结构,建立了气垫炉整体的三维物理数学模型,运用流固耦合FSI分析方法,得到了铝带材热处理气垫炉内的流场分布和铝带材表面的压力分布,以及带材在气垫炉内漂浮换热过程中的变形量。以减小漂浮过程中铝带材的变形量为目的,对气垫炉内导流板和狭缝喷嘴宽度进行改造,结果表明,改造后铝带材最大形变量为13.2 mm,较改造前减少了22.2 mm。
Based on the air cushion furnace structure designed by an aluminum plant in Luoyang city,the three-dimensional physical and mathematical model of the air cushion furnace for aluminum strip heat treatment was established.The flow field distribution in the air cushion furnace and the pressure distribution on the surface of the aluminum strip were obtained by using the fluid solid coupling FSI analysis method,and the deformation amount of the strip during the heat transfer process in the air cushion furnace was also obtained.In order to reduce the deformation of the aluminum strip in the floating process,the width of the guide plate and the slit nozzle in the air cushion furnace was reformed.The results show that the maximum deformation amount of the aluminum strip is 13.2 mm after the reformation,and 22.2 mm is reduced compared with that before.
