3. n. One who or that which removes the scale of protoxid of iron from any plate or beam or other piece of steel or iron undergoing the process of rolling in the rolling-mill. If this scale were left on the surface of the piece, being cooler and harder than the hot metal it would be rolled into the surface at the next pass, or make a blister or pock-mark. In older practice, the scale was swept off by twig-brooms or besoms: water currents are much used with larger masses.
