FIELD: sealing devices for rolls of rolling mills. ^ SUBSTANCE: device for sealing roll mounted with possibility of rotation includes at least one annular body arranged on roll journal and embracing it. Said annular body includes at least one extended tongue closely abutted to stationary construction member at rotation of roll. Said annular body has at least two parts; its first part abuts to roll and its second part has at least one tongue. Second part of annular body is arranged in recess of first part of said body; walls of first part prevent axial displacement of second part. Rolling apparatus has at least one roll mounted in stand with possibility of rotation and at least one sealing device for sealing roll relative to stationary region of rolling apparatus. ^ EFFECT: prevention of axial displacement of parts of sealing device, mechanical stability of device. ^ 8 cl, 2 dwg |
