Abstract
A method for producing bright steel, particularly bar-shaped bright round steel produced from hot-rolled steel. The method includes rounding the round steel coming from rolling heat in a sizing mill to close tolerances, extensively removing the oxide film of the round steel and subsequently subjecting the round steel to a straightening and polishing procedure.
