Device for solidifying a coating layer hot-deposited on a wire, corresponding installation and method

A method for solidifying a coating layer hot deposited on a wire, with a device for solidifying a coating layer hot deposited on a wire, said device extending along a longitudinal direction defining the path of passage of said wire, wherein the device comprises:

• [a] a cooling liquid injection chamber with a cooling liquid inlet and a wire inlet, said injection chamber being cylindrical,
• [b] a cooling chamber with a cooling liquid outlet and a wire outlet,
• [c] a partition arranged between said injection and cooling chambers, comprising a wire passage communicating said injection chamber and said cooling chamber with one another,
• [d] a conduit for separating said wire, extending between said wire inlet and said wire passage,
• [e] said partition comprises a plurality of channels fluidically connecting said injection chamber with said cooling chamber, said plurality of channels leading into the center of said wire passage in an eccentric manner such that each channel of said plurality of channels seen on a plane perpendicular to said longitudinal direction has a first side wall and a second side wall, said first and second side walls being configured such that at least one of them is eccentric to said longitudinal axis, and the other one is at least radial, the prolongation of said first and second side walls being on one and the same side of said longitudinal axis and
• [f] said plurality of channels being inclined forming an angle with respect to said longitudinal direction which is comprised between 10° and 40° for aiming a jet of cooling liquid on said wire in the direction from said injection chamber towards said cooling chamber,
• wherein the method comprises the following steps:
• [g] moving said wire forward along a longitudinal direction of said device by passing said wire between said wire inlet, and said wire outlet, and
• [h] projecting onto said wire a plurality of jets of cooling liquid through the partition comprising the plurality of channels, eccentric with respect to the center of said wire and transverse to said longitudinal direction in the forward movement direction of said wire.
