为优化冷轧机工艺冷却系统的控制,提出冷轧机工艺冷却控制与板形分段冷却控制的各自所需的乳化液流量的计算模型.通过乳化液冷却流量偏差计算出所对应的附加板形偏差量,用于补偿冷轧过程中基本冷却功能与板形控制分段冷却功能二者对不同乳化液流量喷射的工艺要求.进而实现了二种不同工艺功能对冷却流量的优化控制,实现了冷轧过程工艺基本冷却与板形分段冷却之间的组合优化控制,在保证稳定轧制所需的冷却流量前提下,满足了带钢板形质量的良好控制.
In order to optimize the control of the cold rolling mill process cooling system, the calculation models of the respective emulsion flow rates for the cold rolling mill process cooling control and the plate-shaped section cooling control are proposed.The corresponding additional plate shapes are calculated through the deviation of the cooling flow rate of the emulsion The deviation is used to compensate the process requirements of different emulsion flow injection between the basic cooling function in the cold rolling process and the segment cooling function in the plate control section, so as to realize the optimal control of the cooling flow rate by two different process functions, The combined optimization control between the basic cooling process and the plate-shaped section cooling in the cold rolling process satisfies the good control of the strip shape quality under the premise of ensuring the cooling flow required for stable rolling.
