热轧带钢边部质量控制及研究

Quality Control and Research of Hot Rolling Steel Edge Defect

针对本钢1700线生产含Cr带钢出现的边部质量问题进行原因分析,通过增大导尺短行程稳定段的设定、提高出炉温度、减少除鳞投入排数和不投入活套下表面除鳞水等优化,含Cr带钢破边缺陷得到有效控制,边部质量得到改善.

Based on the analysis of the quality of the edge of steel with Cr strip produced by the 1700 line of BenXi Steel,By increasing the setting of the short stroke stability section of the guide ruler,increasing the temperature from the oven,reducing the number of descaling inputs,and optimizing the descaling water on the surface without input,the defect of the broken edge containing the Cr strip was effectively controlled,and the quality of the edge was improved.
