Method for Manufacturing Galvannealed Steel Sheet with Low Permeability

摘要

PURPOSE: A galvannealed steel sheet manufacturing method is provided to manufacture a galvannealed steel sheet from a steel sheet with low permeability using an induction heating method. CONSTITUTION: A method for manufacturing a galvannealed steel sheet with low permeability comprises a step of galvanizing a steel sheet and a step of induction-heating and alloying the galvanized steel sheet by induction heating in the width direction of the steel sheet. A steel sheet with low permeability and a thickness of 0.5-2.5mm is used as a steel sheet to be galvanized.
