| Abstract: | In view of badly thickness variation of SPHD hot rolled coil during cold rolling at Xinyu Iron ＆ Steel Co. , Ltd. , the hot rolling parameters, microstructure and performances of hot rolled SPHD coil were meas- ured and analyzed. The results show that the defect is related to SPHD hot rolled coil horizontal microstructure performance and cross-section shape. By adjusting the hot rolling process and improve roll type, the defect has been eliminated. |
