  • Patent number: 6568459
    Abstract: An apparatus and process for casting a continuous metal strand, in particular steel, in a continuous casting apparatus having strand parts disposed opposite one another and being fitted with bearings in which guide rollers are mounted, and having actuators by which a gap between respective opposed rollers can be set infinitely variable, and which method includes sensing a value representing a compressive force which occurs in the bearings and feeding said value to a computing unit; comparing the individual measured force values of a roller or of a pair of oppositely disposed rollers with respect to a level of the force; and utilizing at least the relating highest value measured as a command variable for controlling the gap and/or the casting rate and/or the amount of cooling water and/or the melt feed and/or the casting powder feed and/or the mold oscillation.
    Type: Grant
