在带钢产品的热轧过程中，表面缺陷会以多种方式演变。在过去的几十年里，已经确定了许多缺陷的原因，并出台了对策，但仍有一个问题尚未解决。这是银条，通常在镀锌(GA)过程后观察到细小的白色线条。提出了一项建议，以确定这一缺陷的可能原因，使用反向材料跟踪来确定来源位置。材料跟踪是最近的一项创新，它依赖基于有限元的模型来提供计算热轧操作过程中材料运动的框架。
Surface defects can evolve in a number of ways during the hot rolling of strip products. Over the past few decades the causes of many defects have been determined and countermeasures introduced, but one issue still remains unresolved. This is sliver, which is usually observed after the galvannealing (GA) process as thin white lines. A proposal is made to determine the likely causes of this defect, using backward material tracking to determine the source location. Material tracking is a recent innovation that relies on FE based models to provide a framework for calculating material movement during hot rolling operations.
