Abstract: A cold rolling mill and method for cold rolling is disclosed. The cold rolling mill includes at least two tandem four-high reversing mills with at least one tension reel on each side of the tandem mills. Bridle roll units may be positioned on each side of the tandem, reversing mills to allow the cold rolling mill to be utilized as a temper mill.

Abstract: A method and plant for casting and rolling strip and/or sheet in line. The method comprises continuously casting slabs less than about 1.5 inches thick which naturally have a columnar grain structure. The method further comprises passing the slabs directly onto an insulated run-out table for maintaining temperature and minimizing heat loss from the slabs and permitting equalization of temperature within the slabs. The method also comprises passing the slabs directly to a hot reversing mill having upstream and downstream coiling furnaces such that the slabs first pass the reversing mill and are subject to an initial reduction in thickness sufficient to break up the columnar structure prior to being coiled as strips in the downstream coiling furnace and passing the strips back and forth to produce sheet or strip having an equiaxed grain structure.

Abstract: A method of underwinding strip on a drum along the passline of a hot reversing mill comprises positioning the drum in a receiving mode, passing the strip through the mill at a given thread speed, detecting the presence of the strip at a given position in relation to the drum, activating the drum in an underwinding direction at a given time delay representative of a distance in which the strip is through the drum slot and internal of the drum, and speed matching the drum and the strip in an initial surface winding mode and a subsequent center driven tension mode.
