面向局部高点控制的工作辊同宽轧制公里数

 为适应市场和节能降耗的迫切需要，提出了工作辊同宽轧制公里数研究，基于金属塑性变形和辊系弹性变形等模型耦合建立起描述带钢断面形状的仿真系统，以带钢断面形状良好即局部高点为控制对象，研究了在不同轧制模式下，工作辊同宽轧制公里数与带钢局部高点的关系。模拟计算和生产试验表明，普通模式下工作辊轧制公里数明显受限于同宽带钢轧制，相比普通轧制，采用合理的窜辊轧制可以大大提高带钢同宽轧制公里数，有效控制带钢局部高点，研究结果对组织轧制生产和制定换辊制度具有重要的指导意义和实用价值。

Research of Work Roll Same Width Rolling Kilometer for Local High Point Control

For the urgent need of meeting market and saving energy, the research of work roll same width rolling kilometer was put forward, and the simulation system of strip profile was established based on coupling the metal deformation model and rolls elastic deformation model etc. Taking local high point of strip as control object, the relationship between same width rolling kilometer and local high point was researched in different rolling mode. The simulated calculation and production experiment shows that work roll rolling kilometer is obviously restricted by same width strip in ordinary rolling mode, compared to ordinary mode, the reasonable shift roll rolling can greatly improve same width rolling kilometer, and local high point of strip is effectively controlled, therefore the research results has the important direction meaning and practical value for organizing production and making change roll system.
