PRODUCTION METHOD OF HOT-DIP METAL STRIP AND DEVICE THEREFOR

摘要

A production method of hot-dip metal strip comprising the step of pulling metal strip into a molten metal bath containing plating metal and depositing molten metal on the surface of metal strip, the step of changing the direction of the metal strip and then pulling out the metal strip without being affected by a dynamic force from the outside of the surface of the metal strip, the step of regulating the deposited amount of molten metal deposited on the metal strip, and the step of controlling the shape of the metal strip in non-contact by a magnetic force immediately before or after the deposition amount regulating step, whereby high-quality hot-dip metal strip can be produced without reducing productivity and without the deposition of dross.
