Method for galvanizing and galvannealing employing a bath of zinc and aluminum |
摘要 |
The present application discloses a method for hot-dip galvanizing and galvannealing which employs a bath of zinc and aluminum. Strips are immersed in the bath to produce substantially dross-free galvannealed and galvanized strips. The bath can have substantially the same effective aluminum concentration during galvannealing as during galvanizing, and the temperature set-point of the bath is at a temperature of about 440° C. to about 450° C.
