摘　　要：经过大量的现场实验与理论研究,将应用数学理论与实际生产工艺相结合,在利用泰勒级数展开并忽略高次项将相关非线性问题简化为线性问题的基础上,通过相关矩阵知识求解线性方程组,并根据牛顿解析法的基本原理,建立了一套适合冷连轧机快速负荷设定的带材中间厚度计算模型,并将其直接应用于某厂1220五机架冷连轧机中间厚度的设定,取得了良好的使用效果,创造了较大的经济效益,具有进一步的推广应用价值。Based on large scale of field experiment and theory research, and by utilizing mathematical treatment method of Taylor series expansion and neglecting the high-order term to simplify the nonlinear problem into the linear problem,and according to the coherent principle of Newton analysis method and matrixes knowledge to solve the linear equation set,it established a set of strip steel intermediate thickness calculation model for the load-quick-set in cold tandem mill. By applying it to the 1220mm five-stander cold tandem mill of one factory ,the enterprise has got large economic benefits. It can be further popularized.
