Control process for twin-roll continuous casting, in which, during casting, the roll separation force (RSF) is measured and the position of the bearings of at least one of the rolls is varied in order to increase or decrease the center-to-center spacing of the rolls, with a view to keeping the force substantially constant, a band (.DELTA.RSF) of force values bracketing a desired nominal force (RSF.sub.0) is predetermined and the position of the bearings is varied more sharply when the value of the measured force lies outside the band than when it lies within the band. Application especially to the twin-roll continuous casting of thin steel strip.
