Abstract: The present relates to an apparatus and method for predicting slab quality including a plurality of meniscus height detecting units prepared in a plurality of region on a top side of a mold receiving molten steel, and detecting a meniscus height of the molten steel, a meniscus flow detecting unit creating a meniscus flow pattern using meniscus heights at the plurality of regions, which are detected by the plurality of meniscus height detecting units, a data storage unit storing the meniscus flow pattern and quality data of a slab produced accordingly and a slab quality predicting unit extracting the meniscus flow pattern detected by the meniscus flow detecting unit and consequent slab quality from the data storage unit to predict slab quality.
