摘　　要：根据唐山某钢厂1 370 mm冷连轧机设备参数,选取等相对负荷目标函数,在一定的约束条件下,优化压下率分配比,并通过蚁群算法的迭代运算,求出负荷最佳分配。仿真结果表明,蚁群算法可以防止目标函数值落入局部极小,优化速度快、收敛性好,可作为冷连轧轧制负荷分配优化方法用于实际生产。Ant colony algorithm was used to optimize load distribution of tandem cold mill. Based on equipment parameters of a certain 1 370 mm tandem cold mill at Tangshan, relative load equalization was taken as object function and reduction distribution ratio was optimized on certain constraint conditions. The optimal load distribution was obtained through iterative operation of ant colony algorithm. Simulated results show that ant colony algorithm can prevent from local minimum of object function value, has fast optimizing speed and good eonstringency. It can be applied to practice as a load distribution optimization method for tandem cold rolling.
