LUBRICATING OIL SUPPLY FACILITY AND LUBRICATING OIL SUPPLY METHOD

WIPO Patent Application WO/2011/126139

A1

A lubricating oil supply facility for supplying lubricating oil to a mill roll (20) of a rolling mill for a plate-like metallic material (M) comprises: spray nozzles (1a, 1b) for granulating or atomizing lubricating oil together with gas and ejecting the mixture toward the mill roll; lubricating oil supply devices (2, 3, 4) for supplying the lubricating oil to the spray nozzles; and gas supply devices (5, 6) for supplying the gas to the spray nozzles. The amount of supply of the lubricating oil from side spray nozzles among the spray nozzles is set to be greater than the amount of supply of the lubricating oil from the center spray nozzle among the spray nozzles. Also, the amount of supply of the lubricating oil from the spray nozzles located between the center spray nozzle and the side spray nozzles is set to be less than or equal to the amount of supply of the lubricating oil from the side spray nozzles and greater than or equal to the amount of supply of the lubricating oil from the center spray nozzle. As a result of the configuration, the occurrence of nonuniform wear and surface roughening of the mill roll in the axial direction thereof is minimized.
