FIELD: foundry engineering. SUBSTANCE: device has one or two rolls set in rotation. Rolls walls are cooled with water. Two lateral walls 3 form casting space 4. Each roll surface is divided at least for three circular zones. At least one of them has roughness exceeding roughness of the others. Preferably only several longitudinal skin zones of casting metal hardened through a contact with cooling walls of rolls or a roll. EFFECT: improved design. 9 cl, 4 dwg
