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.
