MANUFACTURING GALVANNEALED SHEETS BY HEAT-TREATING ELECTROLYTICALLY FINISHED SHEETS |
摘要 |
The invention relates to a method for manufacturing a steel strip with a cathodic corrosion protection coating, in which the steel strip is hot rolled and then cold rolled; the steel strip is subjected to an electrolytic galvanization and after the electrolytic galvanization, the steel strip is heat treated in a bell-type annealing furnace at temperatures of 250° C. to 350° C. for a period of 4 to 48 hours and this produces a zinc/iron layer.
