Abstract
Twin roll caster for casting thin steel strip comprises chilled 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 substantially constant gap is maintained between the rolls such that unsolidifed 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 constant and low biasing forces, which may be between the same and slightly more than the force required to balance the hydrostatic pressure of the casting pool and to overcome the mechanical friction involved in moving the biased roll.
