Abstract Scope |
Cold rolled wide steel strip is mainly used in all kinds of large size covers or structural parts of automobile body, and its production technology is more difficult than ordinary products, especially in the continuous annealing process, the edge scratch defects of products have a great impact on the surface quality and production efficiency. Based on the analysis of the microstructure and morphology of the defects, combined with the production process and equipment, the results show that the edge scratches of the cold rolled wide strips mainly come from the surface defects of hearth rollers in the preheating and cooling sections, and some from the acid rolling process. Meanwhile, some countermeasures to reduce or prevent the edge scratch of cold rolled wide steel strip are proposed. |
