| Abstract: | In this paper, some quality problems were analyzed which were found in sheet production process of the hot rolled IF steel automobile original plate, such as temperature deviation ,edge black line, width narrow, coiling indentation. According to the practical production , some improvement measures were proposed including increasing slab dropping-out temperature, optimizing E1 roll camber, descaling process, control parameters and method of U coiling process, and speed scheme of finishing mill and adjusting the unit tension of loop. Based on these measures, the quality of IF steel sheet were improved and the stable production was realized. |
