Abstract
A method of improving control of thin strip produced by continuous casting including the steps of assembling a continuous casting apparatus having a pair of counter-rotating cooling rolls, having a nip there between and at least one enclosure downstream from the nip, introducing molten metal to form a casting pool supported on the cooling rolls above the nip and counter-rotating the cooling rolls forming cast strip downwardly from the nip, guiding the strip through the at least one enclosure downstream from the nip, the at least one enclosure having gas inlets for directing oxygen-containing gas into the enclosure, and directing oxygen-containing gas having a desired amount of oxygen through the inlets into the enclosure to provide an atmosphere 0.5% and 15% oxygen with between 3 and 10% humidity to oxidize at least one surface of the strip a desired thickness of scale on the surface of the strip to provide less mill force and downstream control of the strip.
