Abstract

A method of descaling the heat rolled steel strip, which is characterized in that: prior to acid washing, the heat rolled steel strip with heat rolled oxidized skin attached thereto is subject to high pressure rolling and scrubbing to remove the oxidized skin, and the relationship between the thickness of the heat rolled oxidized skin t(μm) and the rolling press ratio R(%) is maintained at t x R ≧150.
