METHOD FOR MANUFACTURING GA STEEL SHEET

摘要

A steel strip was coiled after galvanizing treatment on the continuous galvanizing line by the conventional method, charged in batch annealing furnace, heated to 380-410 deg. C for 5-10 hours for maintaining the Fe content in the galvanized layer to 8-15.0%, and cooled in furnace or at room temperature to give a galvanized steel strip using batch annealing furnace.
