FIELD: metallurgy.
SUBSTANCE: invention can be used at continuous casting of cracking susceptibility steels into mold of length 700-1200 mm. Mold contains bearing plates with wide and narrow operating walls of equal length, fastened to each other. Narrow operating walls are implemented with vertical groove of length 600...800 mm from top shear of narrow wall and of depth 15...20 mm. Groove existence provides alignment of thermal profile on ingot surface, reduction of stress in ingot sinterskin.
EFFECT: increasing of mold life and improving of casting block.
