摘　　要：结合双辊立式铸轧机设备和技术参数,通过流-固耦合的方法进行了变参数正交模拟研究,揭示了1×××系铝液浇铸温度和铸轧速度对铸轧复合区内温度场、流场的影响。研究结果表明,最优铸轧参数区间为浇铸温度670~690℃、铸轧速度12~13 m/min。浇铸温度越高、铸轧速度越快越容易发生漏液,反之容易发生轧卡。Combined with the equipment and technical parameters of two-roll vertical casting and rolling mill,a variable parameter orthogonal simulation study has been carried out by the method of fluid-solid coupling,revealing the effects of casting temperature and casting speed of 1×××aluminum liquid on the temperature and flow fields in the casting and rolling composite zone.The results show that the optimum casting and rolling parameters range is casting temperature at 670~690℃and casting and rolling speed at 12~13 m/min,the higher the casting temperature and the faster the casting and rolling speed,the more likely the leakage will occur,and otherwise the nip would occur easily.
