在考虑轧机设备能力限制、提高产量和产品质量、减少能耗的基础上,建立了按功率最大化轧制策略的冷连轧机轧制负荷分配优化数学模型,并开发了MATLAB程序。通过仿真实例证明,该算法计算速度快、精度高,克服了传统的负荷分配模型中求解非线性方程组时对初值要求苛刻、计算速度慢的缺点,适用于冷连轧机初始压下分配和轧制规程的离线模拟计算,为模型在线控制奠定了基础。
Based on the limitation of capacity of rolling mill equipment, the improvement of output and product quality, and the reduction of energy consumption, a mathematic model of rolling load distribution optimization for tandem cold rolling mill based on power maximization rolling strategy was established and a MATLAB program was developed. The simulation example proves that this algorithm has the advantages of fast calculation and high precision. It overcomes the shortcomings of the traditional initial load distribution model when solving nonlinear equations, such as poor initial value and slow calculation speed. It is suitable for the initial pressure distribution and Off-line simulation of rolling procedures, which laid the foundation for model online control.
