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.

Manufacturing methods and apparatus for targeted cooling in hot metal rolling

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 Rand Rare fully saturated fatty acyl radicals derived from saturated fatty acids containing from about 10 to 22 carbon atoms; and Ris 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.
