Beschreibung
Zusammenfassung:	FIELD: rolled stock production, namely manufacture of cold rolled metal. SUBSTANCE: method comprises steps of successively deforming blank between rolls; supplying technological lubricant onto blank and rolling rolls; feeding oil in liquid friction bearing assemblies of rolls; periodically changing backup rolls and before such operation releasing pressure in pipeline for feeding oil into liquid friction bearings and disconnecting hoses for feeding oil and discharging it from bearing assemblies. Novelty is blowing compressed air to liquid friction bearing assemblies through pipeline for feeding oil before disconnection of hoses for feeding oil and discharging it. Then compressed air pressure is released and feed pipeline is connected with draining tank. EFFECT: elimination of penetration of oil used for lubricating liquid friction bearing assemblies into system for supplying technological lubricating and cooling agent, lowered oil consumption fed to liquid friction bearing assemblies. 2 dwg
