Abstract
A method for continuously removing scale from a hot-rolled carbon steel strip includes: cracking the scale on the hot-rolled steel strip; shot-blasting the cracked scale to remove the scale; deforming the hot-rolled steel strip so as to weaken the bond between scale remaining after the shot-blasting and the hot-rolled steel strip and so as to impart surface roughness to the hot-rolled steel sheet; and polishing the deformed hot-rolled steel strip to remove the remaining scale.
