  • Remote-controlled infinitely adjustable roll stand
    Patent number: 4034797
    Abstract: A roll stand for use in the roll racks of a continuous casting machine is disclosed in which the distance between the rolls is capable of infinite adjustment and is remote-controlled. Through the use of screw jacks supporting the top rolls, infinite adjustment is attained within the upper and lower limits of the jacks. The system is remote-controlled through the use of hydraulic motors for operating the jacks. Positive locking of the rolls in position is achieved through the use of wedge-shaped tapered keys.
