ResultTo create a high-quality surface for rolling, the broadest sides of a metal ingot are shaved by a machine with rotating blades, called a scalper. Scalping removes any irregularities or unwanted chemical compositions left on the surface of the ingot by the casting process. The scalper uses large horizontal blades with a span of …
