PURPOSE:To reduce an initial investment of rolling mill equipment by installing a thin-slab continuous casting machine, an edging device, and a descaler in series and incorporating forcing rolling-rolls and multiple high-draft rolls in a common housing, to form a rolling line. CONSTITUTION:A soaking pit 6, an edging device 7 and a descaler 8 are installed in series at the outlet side of a thin-slab continuous casting machine 5. Further, a multiple high-draft roll-structure 16 equipped with a 2-high forced rolling roll-structure 13 and a pair of work rolls, is incorporated in a common housing, and a hot high-draft mill 9 is disposed at the back side of the descaler 8. The distance between the roll structure 13 and the roll structure 16 is small because they are incorporated in the common housing, and the temperature drop of a rolling material 2 is small. Further, because the rolling mill equipment is simplified into two passes, both of its initial investment and energy loss are reduced. |
