Abstract: A rolling mill apparatus and methods of hot rolling with targeted cooling. In one aspect, a mill having multiple roller stacks includes a cooling system that directs the bulk coolant flow to a heat exchanger having first and second heat exchangers in parallel. The first heat exchanger is adapted to cool the heated coolant to a first temperature for use in a first coolant stream discharged through a first set of nozzles during rolling, while the second heat exchanger is adapted to cool heated coolant to a lower temperature for use in a second coolant stream at a second temperature lower than the first for discharge through a second set of nozzles downstream to facilitate rolling or coiling of the rolled metal.

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

Abstract: A lubricant for food, beer or beverage container and container component stock is provided containing, as a conductivity enhancing additive, a phospholipid having a structure of Formula (I): wherein R1 and R2 are fully saturated fatty acyl radicals derived from saturated fatty acids containing from about 10 to 22 carbon atoms; and R3 is selected from the group consisting of choline, salts and mono- salts of Group I and II metals and fatty acid neutralized ethanolamine. Lubricant formulations are also described, comprising 0.5 to 50 wt % fatty acid ester of propylene glycol, 0.5 to 90 wt % petrolatum and 0.5 to 90 wt % mineral white oil. Finally, a lubricant for metalworking is described, containing as a load-bearing additive, a fatty acid monoester of propylene glycol as given by Formula (II): wherein n is from 7 to 21 and in which the acyl moiety is hydrogenated to maximize saturation.
