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 displacement casing for the metal strip. The casing includes an upper portion and a lower portion. The lower portion includes a pouring box delimiting at least two liquid metal pouring compartments. Each pouring compartment is inwardly delimited by an inner wall including an upper rim. The casing is provided with the pouring box, is rotatable relative to the metal strip around a first rotation axis and the pouring box is rotatable relative to the upper portion of the casing around a second rotation axis. A method for coating the metal sheet is also provided.

A flux composition which includes one or more organic compounds including one or more sulfonic acid groups, salts or anhydrides thereof is applied to tin or tin alloy deposits. The flux composition is then homogenized on the tin or tin alloy to inhibit tin or tin alloy oxidation and improve brightness of the tin or tin alloy.

A tinsel wire structure and a manufacturing method thereof are provided. The tinsel wire structure has a core, a conductive layer and a metal cladding layer. The core has an outer surface and defines a length direction. The conductive layer is spirally wound along the length direction on the outer surface of the core. The metal cladding layer is provided on the periphery of the conductive layer to cover the core and the conductive layer. The conductive layer is spirally wound on the outer surface of the core in a non-overlapping manner to define a gap so that the gap is spirally wound on the outer surface of the core in a non-overlapping manner. When the metal cladding layer covers the core and the conductive layer, the metal cladding layer covers the gap at the same time.
