, Eu-1, the shape of the steel strip S is controlled by adjusting the pushing inertia ΔS of the υ-dipped/4 snap roll 2 in the zinc bot 1. This method using snap rolls has problems with roll arrangement, roll diameter management, and the occurrence of indentation scratches. Many aspects of operation also depend on the skill of the operator, making adjustments difficult. Therefore, there is a limit to the shape modification of the copper strip.
