Technical transformation for improving operation stability of the charging table frame in the medium and heavy plate plant
In this paper, the analysis and demonstration are conducted in view of the guiding function failure of the guide carriage of the steel billet charging table frame, the high failure rate of the charging ta⁃ble as well as the unreasonable design in medium and heavy plate plant of Tianjin Iron and Steel Group Co., Ltd., the technical transformation scheme for the overall structure of the charging table frame is pro⁃posed, and which is redesigned. The transformation scheme changes tthe guide carriage of the steel billet charging table frame from the existing frame guide wheel guiding form to the guide column guiding form , so the strength of the charging table frame is enhanced, the position of the hydraulic cylinder is changed and the stroke of the hydraulic cylinder is shortened. After the implementation of the transformation scheme, the charging table frame rises and falls steadily, the original guiding function is restored, the load of the lifting hydraulic cylinder is reduced, and the stability and safety of the equipment operation are effectively improved.
