Patent ID: 7584779

Claim:
A twin roll casting machine comprising: (a) a pair of water-cooled casting rolls laterally positioned to form a nip therebetween and counter rotatable about rotational axes thereof, with the casting rolls biased towards each other by thrust forces; (b) rotary joints coupled to at least one end of the casting rolls and capable of supplying cooling water into and removing cooling water out of passages in the casting rolls, with the rotary joints of each casting roll being arranged so that the flow of cooling water into the rotary joints and the flow of cooling water out of the rotary joints exert forces on the casting rolls generally in the direction along the rotational axis of the casting rolls; (c) cooling water supply hoses connected to the rotary joints; and (d) biasing units capable of supporting the hoses such that the mass of the hoses is not carried by the casting rolls.
