ABSTRACT:
Twin roll casters for casting thin steel strip comprise cooled casting rolls mounted on carriers. One roll is fixed and the other is moveable laterally and biased toward the other roll by carrier drive units acting on the moveable roll carriers. A casting pool of molten steel is supported on the rolls which are rotated to produce a solidified steel strip delivered downwardly from the nip therebetween. A gap is regulated between the rolls such that unsolidified molten metal passes through the nip between the solidified shells of the forming strip and solidifies below the nip. The carrier drive units are effective to apply to the biased roll substantially intermediate biasing forces such that the roll separation force at the casting rolls is regulated to a value between 2 and 4.5 Newtons per millimeter.
