The type of this article is " used for product " . it analyzes surface pollution of metal , hydro capacity and effect to wall piping quantitatively on the base of the rinsing of piping of hydraulic system of precise - rolling machine at the hot sequential rolling plant . by analysis , we confirm the fit flux and pressure when rinsing , design high - ability , high - efficiency , wide - applicability whole set equipment 本论文的成果直接用于生产，以太钢热连轧精轧机液压系统的钢管清洗为背景，对金属表面污染进行分析，对液压钢管冲洗时流体的性能和其对管道内壁的作用效果进行定量的分析，确定合适的冲洗流量和冲洗压力，设计制造了能力大、效率高、效果好、适用广的成套装置。
Because of optimizing its control system , so first we mention a amending algorithm to referring the model of the extract millings iron force based the aims and the tasks of optimizing design , then reduce an applicable forecast algorithm based forecasting and simulating . so we have a lot of discussion as follows 由于要对其控制系统进行优化设计，所以基于优化设计的目标和任务，我们提出了一种改进的算法首先对精轧机组的轧制力模型进行了讨论，然后对其进行了预测和仿真，得到了一个实用的预测算法。
It not only makes rolling rules more proper , but also designs rolling mill economically and timely , and utilize expert experience efficiently , and develops a new way for finishing mill design and product price decision intelligently . therefore , it is a task with important theoretical value and practical significance 这不仅使轧制规程的制定更趋合理，而且有利于克服轧机设计周期长、经济性能差的缺点，并能有效地利用专家的经验知识，为热连轧精轧机设计的智能化和帮助决策者进行产品报价决策活动开辟了一条新路，是一个具有理论价值和实际意义的课题。
