Abstract:
A method for applying a liquid lubricant to a horizontally moving metal sheet, the method comprising:supplying the lubricant to a plurality of conduits; spreading the liquid lubricant over at least one wick from the conduits above the wick to provide a spread lubricant flow; moving the spread liquid lubricant through the at least one wick by gravity flow without the application of an external mechanical force to generate a resulting pressure through the wick to move the liquid lubricant therethrough, the wick supplying liquid lubricant to the moving metal surface by capillary flow of the lubricant through the wick; and applying the liquid lubricant from the wick to the moving metal sheet, the supply of liquid lubricant from the conduits and the thickness and density of the wicks effective to provide a generally uniform coating of liquid lubricant to the metal sheet at variable traveling rates of the metal sheet.
