ABSTRACT:
In apparatus for continuously casting metals between endless moving belts, a pulley device for carrying a casting belt, including outer, belt-supporting structure having at least two belt-engaging surface zones respectively located on opposite sides of the median plane of the pulley, wherein at least one of the two zones is variable in circumference with respect to the other of the two zones for adjusting the transverse profile of the belt-supporting surface of the pulley. The pulley device in one form comprises a belt-supporting structure which is circumferentially expansible at each of two surface zones and means for effecting controlled expansion of the structure separately at each of the two zones. A method of steering a casting belt, in continuous casting procedure, includes the steps of advancing the belt over a pulley around which the belt is trained and varying the circumference of one surface zone of the pulley with respect to another surface zone of the pulley for adjusting the lateral contour of the pulley surface to counteract a tendency of the belt to move laterally on the pulley.
