随着轧钢自动化程度和对产品质量要求的提高,对数学模型精度也愈来愈注意,因而国内外都在致力这方面的研究,由于轧制压力模型是一个主要模型,提高轧制压力计算精度就必然成为重要的研究课题。就冷轧而言,轧制压力模型大多是建立在工程近似解法基础之上,其中尤以采里可夫方程和D、R、Bland方程应用最为普遍,据此再导出简化的代数方程或统计方程以适于在线控制。本文是对现有主要轧制压力方程本身进行分析比较。 With the degree of automation of rolling steel and the improvement of product quality requirements, more attention is paid to the accuracy of mathematical models. Therefore, researches in this field both at home and abroad are devoted to the study. Since the rolling pressure model is a major model, the accuracy of rolling pressure calculation It must become an important research topic. In terms of cold rolling, the rolling pressure model is mostly based on the approximate solution of engineering, especially the mining of Leakoff and D, R, Bland equation is the most common application, and then derive simplified algebraic equations or statistics The equation is suitable for online control. This article is to analyze and compare the existing main rolling pressure equation itself.
