Hot rolling process is a very intense energy consuming process and deformation energy is one of the major cost items. Deformation energy consumed in hot rolling process is highly related with the design of the roll pass sequence. In this study, response surface methodology (RSM) is utilized to optimize minor geometric parameters i.e. radii and angle in a box pass design. Set values of the independent variables of the constructed response surface have been determined by central composite design (CCD). Simulation experiments based on finite element method have been used to estimate deformation energies. Methodology used in the simulations have been verified by modelling an industrial production process and comparing the simulation results with the industrial data. Optimization has been verified by applying the optimized radii and angle values to a roll pass sequence with 5 stages. Decrease in deformation energy by 7.44% has been established by optimization with respect to conventional roll pass design.

响应面在热轧辊道设计优化中的应用

热轧过程是一个非常耗能的过程，变形能是主要的成本项目之一。热轧过程中消耗的变形能与轧制道次顺序的设计高度相关。在这项研究中，利用响应面方法（RSM）在盒式设计中优化次要几何参数，即半径和角度。已通过中央复合设计（CCD）确定了构造的响应面的自变量的设定值。基于有限元方法的仿真实验已被用来估计变形能。通过对工业生产过程进行建模并将模拟结果与工业数据进行比较，已验证了模拟中使用的方法。通过将优化的半径和角度值应用于具有5个阶段的滚动过程序列，已验证了优化。相对于传统的辊道设计，通过优化已将变形能降低了7.44％。
