HOT-ROLLED STEEL SHEET, METHOD OF MANUFACTURING THE SAME, AND EQUIPMENT FOR MANUFACTURING THE SAME |
| 摘要 |
A method of manufacturing a hot-rolled steel sheet is explained. The method includes hot-rolling a slab, performing a first phase transformation process cooling a surface of the hot-rolled slab to phase-transform a structure of a surface portion of the hot-rolled slab, performing a second phase transformation process to phase-transform a structure of a central portion of the hot-rolled slab after the first phase transformation process, and coiling the slab including the phase-transformed surface portion and the phase-transformed central portion. |
