FIELD: ferrous metallurgy, namely continuous casting of steel.
SUBSTANCE: built up mold includes cooled plates with vertical ribs in zone of coupling plates. Relation of legs a, b forming ribs is in range 1 : (1.5 -2). Relation of small leg w forming vertical ribs to small side h of mold is in range 1 : (50-60). Relation of large leg b forming vertical ribs to large side l of mold is in range 1 : (30 - 330. Relation of small side h to large side l of mold is 1 : 1.1 at total surface area of mold 990 sq.cm.
EFFECT: enhanced quality of surface of continuously cast billets, increased strength of mold.
