The flow dynamics at the meniscus level of the mold have an important impact on operational conditions and quality of cast products during continuous casting. Abrupt mold surface velocity variation brings asymmetry on the surface directed flow, therefore forming internal and surface defects in the final cast products. The local turbulent flow can be dampened instantaneously with the use of electromagnetic forces, known as electromagnetic brake (EMBr). The impacts of EMBr on the surface velocity, mold powder entrapment rates, and the surface fluctuation heights at different mold widths and casting speeds are analyzed to provide a better knowledge and understanding.
