APPARATUS FOR MANUFACTURING A GALVANIZED STEEL SHEET WITH REDUCING DROSS AND A METHOD FOR MANUFACTURING THE STEEL SHEET USING THE SAME, CAPABLE OF RESTRAINING THE GENERATION OF THE DROSS WITH PRE-PLATING THE SURFACE OF THE STEEL SHEET WITH AN EFFECTIVE THICKNESS

摘要

PURPOSE: An apparatus for manufacturing a galvanized steel sheet with reducing dross and a method for manufacturing the steel sheet using the same are provided to uniformly form a galvanized layer and to improve productivity through a continuous manufacturing process.;CONSTITUTION: An apparatus for manufacturing a galvanized steel sheet with reducing dross includes a plating bath (110), a snout (120), and a pre-plating unit (130). The plating bath houses a galvanizing bath. The snout guides the steel sheet to be plated to the galvanizing bath inside the plating bath. The pre-plating unit inside the snout forms a pre-plating layer on the steel sheet before the steel sheet is galvanized. The pre-plating unit has a metal depositing furnace inside which a process for depositing metal on the surface of the steel sheet is implemented.;COPYRIGHT KIPO 2013
