Method of improvement of the surface quality of a continuous casted slab

摘要

The surface quality of a continuously cast thin slab is improved by application of a reactant, other than water, onto the slab before or during descaling. A process for improving the surface quality of a slag and scale covered continuously cast slab (2), especially a thin slab of NOTGREATER 100 mm cast thickness (d), comprises applying a reactant (6) other than water, onto the slab before or during descaling prior to rolling in a finishing train (9).
