摘要
某冷轧厂在光整过程中,在IF带钢表面两侧约100 mm范围内出现色差。通过有限元分析软件MSC.Marc建立了光整的三维动态有限元模型,并对工作辊施加弯辊力。对光整过程进行动态仿真研究,分析了IF带钢表面轧制应力分布与摩擦因数之间的关系,最终找出了色差产生的原因,并提出了改进措施。
Chromatic aberration appeared about 100 mm width on both side surfaces of IF strip during skin roiling in a cold rolling factory. A three dimensional dynamic finite element model of the skin rolling process was established by means of MSC. Marc software, and the roll bending force was applied to the working roll. Subsequently, the dynamic emulation on the skin rolling process was performed, and the effect of friction coefficient on roiling stress distribution at the IF strip surface was analyzed. Finally, causes of the chromatic aberration generation were discovered, and the corresponding precautions were put forward.
