Abstract
A method of rolling metal in a plurality of rolling stands with each of the stands having two or more rolls. The method includes first polishing the surfaces of the rolls to a mirror finish, after which the roll surfaces are textured with a plurality of minute micron size craters. The roll surface and craters are then coated with a dense, hard material before the rolls are lubricated and used to reduce the thickness of the metal in the stands. To this end, the metal is directed through the stands, the craters being capable of retaining and carrying lubricant into the bites of all of the rolls without substantial adherence of metal to the roll surfaces and without substantial generation of wear debris on the surfaces of the rolls and rolled material.
