| 1 | Constructing a data platform for surface defect management using a multidimensional database显示文摘Surface quality has been one of the key factors influencing the ongoing improvement of the quality of steel.Therefore,it is urgent to provide methods for efficient supervision of surface defects.This paper first expressed the main problems existing in defect management and then focused on constructing a data platform of surface defect management using a multidimensional database.Finally,some on-line applications of the platform at Baosteel were demonstrated.Results show that the constructed multidimensional database provides more structured defect data,and thus it is suitable for swift and multi-angle analysis of the defect data. | SU Yicai OU Peng GAO Wenwu | 2013 | Baosteel Technical Research2013，7，4： | 0 |
