(S069)Improvement on CC Technology of Auto Exposed Panel for Surface Defect Control -3 Control of Flow F Field ield in the M Mold old

摘要

The formation of surface defects on cold rolled sheets is clos closel ely related to the flow field y in the CC mold. The simulated calculation and water mo modelling elling experiment are the important importantly ly conventional methods to study the flow field of molten steel in the CC mold. However, the two method methods are still the indirect one ones. s. Ther Therefore, it is efore, highly desirable to measure the velocity of molten steel dire directly for ctly study studying ing the flow field in the CC mold.
