Manufacturing methods and apparatus for targeted lubrication in hot metal rolling

Rolling mill apparatus and methods of hot rolling with targeted lubrication are provided herein. A rolling mill apparatus having multiple roll stacks (A, B, C) may include a cooling fluid pump (10) and a lubricant pump (20) fluidly coupled with cooling nozzles (24) and lubrication nozzles (25) through a piping system. The piping system may be configured such that the lubricant pump (20) introduces neat lubricant that mixes with the cooling fluid to form a lubricating fluid as loose lubricant emulsion for discharge to select roll stacks (A, B, C) through one or more lubrication nozzles ( 25), while one or more cooling nozzles (24) discharge the cooling fluid without the added lubricant. The lubrication nozzles (25) may be aimed to target discharge of the lubricant emulsion to the bite roll. Modifications to mill headers (24) to provide targeted lubrication in accordance with the invention are also provided.
