Hot Strip Mill. The Hot Strip Mill is where CSI's rolling operations begin, as steel slab is reheated and rolled to hot rolled coil. With an annual capacity of more than two million tons, the rolling mill is more than a half-mile long and includes a walking beam reheat furnace, a two-high scalebreaker, five four-high roughers, a crop shear, six four-high finish mills, and two downcoilers.
