FIELD: technological processes.
SUBSTANCE: invention relates to rolling and is intended for retention of viscous material, for example, coolant, on roll (130) and / or material processed during rolling, for example, metal strip. Device (100) for holding viscous material comprises movable seal (110) and gas supply device (120). Method of roll cooling (130) may include application of viscous material, such as coolant, on roll (130) and retention of viscous material on roll (130) by means of device (100) for retention of viscous material. In some cases, viscous material retention device (100) can be used to facilitate removal of viscous material from roll (130) and / or material to be rolled.
EFFECT: invention makes it possible to prevent accumulation of used process viscous material.
