Abstract��Dimple and cavity defects will appear on the W800 hot-rolled strips when being rolled of non-oriented electrical steel W800 plate, the causes were analyzed by the metallographic and chemical components analysis. The results show that the dimple defects were generated from the external abnormal substances with the strip impacting and rubbing the side guide plates, a lot of external abnormal substances were produced on the surface of strip, hence the external abnormal substances were rolled into the strip surface and peeled off when coiled. The edge breach defects resulted from the impacts between the strip and the side guide plates and the cavity defects from the external small grain abnormal substances rolled into the strip with inconsistent deformation.
