Abstract
A mold powder for use in continuous casting, containing specified amounts of CaO, Al.sub.2 O.sub.3, TiO.sub.2, Li.sub.2 O, BaO, MgO, F and Na.sub.2 O, and further containing at least one of BN and C as aggregate. The mold powder, when used in continuous casting of a steel rich in strong reducing metal elements such as Al, Ti, REM and so forth, remarkably suppresses generation of deterioration in the surface quality of the slab and break out of the slab which are attributable inferior lubrication.
