A method and apparatus for manufacturing hot strip steel includes a continuous slab caster adapted to cast a strand of 4 inches or more in thickness. The strand is cut to slab length and heated in a roller hearth furnace or a walking beam furnace prior to entry into a multi-stand tandem reversing mill. The slab is rolled in a downstream direction through the mill in a first reducing pass. The mill is reversed and the elongated slab is rolled in an upstream direction through the mill in a second reducing pass. The intermediate bar exits the upstream end of the mill and is coiled in a coil box positioned intermediate the furnace and the reversing mill. The bar is then unwound from the coil box for rolling in the downstream direction through the mill in a third and finish pass. The finish gauge strip moves down a run out table downstream from the mill for coiling in a down coiler apparatus.
