Abstract:
A coated metal sheet includes a steel substrate and a coating on at least one surface of the steel substrate. The coating includes between 0.2 and 0.7% by weight of Al, with a remainder of the metal coating being Zn and inevitable impurities. The coated metal sheet was subjected to a skin pass operation after coating. An outer surface of the metal coating has a waviness Wa0.8 of less than or equal to 0.55 μm.

A steel part includes a steel sheet substrate and a coating on at least one surface of the steel sheet substrate. The coating includes between 0.2 and 0.7% by weight of Al, with a remainder of the metal coating being Zn and inevitable impurities. The steel sheet substrate and the coating have at least one deformation. An outer surface of the coating has a waviness Wa0.8 of less than or equal to 0.43 μm.
Abstract:
An apparatus for the continuous hot dip coating of a metal strip is provided The apparatus includes a vessel intended to contain a liquid metal bath, a bottom roller and a scroll casing of the metal strip. The casing includes, at its lower end, a pouring box delimiting a front pouring compartment for liquid metal and a rear pouring compartment for liquid metal. Each pouring compartment is inwardly delimited by an inner wall and outwardly delimited by an outer wall. The outer wall of the rear pouring compartment forms, with the passage plane of the metal strip, an angle greater than or equal to 15° in the usage configuration. A method is also provided.
