PROBLEM TO BE SOLVED: To provide a lubricant supply facility and a lubrication rolling method capable of preventing generation of deposition unevenness and deposition failure of lubricant to a metal strip due to collision and interference of vertical lubricant injection flows on outside of a plate width direction of the metal strip, and capable of supplying lubricant to the metal strip uniformly in injecting and supplying the lubricant with gas to vertical surfaces of the metal strip on an inlet side of a rolling mill by using a lubrication header having a two-fluid nozzle in cold rolling of the metal strip.SOLUTION: An area ratio of areas 53w, 53d on which vertical injection areas overlap with respect to a lubricant injection area on outside of a width direction of a metal strip 2 on a surface of plate height of the metal strip is suppressed to 50% or less. In order to achieve it, positions of the vertical lubricant headers are shifted to a rolling direction. In addition, vertical rolling headers are inclined to an opposite side of the rolling direction. |
