Background

The steel is oxidized at high temperature to form a layer of compact iron scale on the surface. If this layer of scale cannot be removed before rolling, it can be pressed into the surface of the strip by the rolls during rolling, which affects its surface quality. The residual iron oxide scale can also accelerate the abrasion of the roller and reduce the service life of the roller. If the strip steel needs to be acid-washed, the residual iron oxide scale can increase the difficulty of acid-washing and increase the acid consumption. Therefore, before billet rolling, the scale on the surface must be removed. The method for removing the iron oxide scale (removing phosphorus by high-pressure water) by utilizing the mechanical impact force of high-pressure water is the most effective method at present.
