Casting metal strip by delivering molten metal to a casting pool (81) supported on a pair of parallel casting rolls (16) and passing metal downwardly between the rolls to produce solidified strip (20). Flow of metal to the casting pool (81) is controlled by an input flow control valve (47). At start of casting when pool (81) is being filled speed of rolls (16) is varied in response to variations between actual instantaneous pool level and predicted level until pool approaches desired operational level. Thereafter any varia- tions between instantaneous roll speed and desired operational roll speed are caused to adjust valve (47) to being pool level and roll speed to desired operational valves.
