Electromagnetic brake (EMBr) has been applied in the molten steel to control the meniscus characteristics and stabilize the meniscus fluctuation. The nail dipping method has been developed to actively determine the mold top surface velocity in a certain slab caster. The shape of the meniscus profile and direction of flow are quantified by analyzing the angular profile of the lump for each solidified nail, which indicates that the meniscus level fluctuates with time variation and the EMBr can make the meniscus level flatter and slower. The correlation between the height difference of the solidified lump on the nail and surface velocity is confirmed and extended. The error evaluation for each lump measurement is also discussed. Furthermore the effect of magnetic field on the fluid flow in the mold has been investigated.
