The control of the liquid metal flow and the damping of surface fluctuations are predominant objects connected with the operation of wide mould casters. Investigations on a full scale water model reveal that the casting speed, the immersion depth of the entry nozzle, and the lift gas injection rate have to be tuned carefully for the benefit of optimal flow conditions in the CC‐mould. When casting conditions are changed, it is necessary to adjust the free parameters correspondingly in order to maintain smooth casting operation and high ranking strand quality.
