Abstract (en)
[origin: WO2014177605A1] The signal obtained by measuring a mold level (5) is analyzed, the occurrence of irregular strand bulges (8) is recognized and the stopper rod movement is boosted and adapted by adding an additional control algorithm to the mold level controller (10) such that the variations of the mold level (5) about the target level can be maintained in a predetermined range of ± 1.0 to ± 3.0 mm.
