Device (1) for solidifying a coating layer hot deposited on a wire (108), corresponding installation and method. The device comprises a cooling liquid injection chamber (2) with a liquid inlet (6) and a wire inlet (4), a cooling chamber (8) with a liquid outlet (12) and a wire outlet (10), and a partition (14) arranged between the injection and cooling chambers (2, 8), comprising a wire passage (16). It also has a conduit (22) for separating the wire (108). The partition (14) comprises channels (18) fluidically connecting the injection chamber (2) with the cooling chamber (8) and leading into the center of the wire passage (16) in an eccentric manner and being inclined forming an angle (α) with respect to a longitudinal direction (L). This directs a jet of cooling liquid on the wire (108) in the direction from the injection chamber (2) towards the cooling chamber (8).

Disclosed is a steel sheet for hot press forming, which includes: a base steel sheet; and a plating layer disposed on the base steel sheet and including a diffusion layer and a surface layer that are sequentially laminated, wherein the diffusion layer includes an Fe—Al alloy layer and an Fe—Al intermetallic compound layer that are sequentially disposed on the base steel sheet and each include silicon, and an area fraction of the Fe—Al intermetallic compound layer with respect to the diffusion layer is 84.5% to 98.0%.

Provided is a zinc alloy-plated steel material used in automobiles, building materials, home appliances, or the like, and more specifically, to a zinc alloy-plated steel material having excellent corrosion resistance and surface quality, and a method for producing same.

A hot-dip-coated, non-skin-passed, cold-rolled metal strip is provided. The metal coating of the metal strip includes a waviness Wa.sub.0.8 of less than or equal to 0.70 μm, 0.2 to 8% by weight of aluminum and magnesium, and up to 0.3% by weight of additional elements, the balance being zinc and inevitable impurities. Metal parts are also provided.

Provided is a plated steel material which can be used for an automobile, a household appliance, a building material, and the like and, more specifically, to a zinc alloy plated steel material having excellent surface quality and corrosion resistance, and a method for manufacturing the same.

A gas wiping nozzle configured to blow wiping gas onto a metal strip includes a first nozzle member and a second nozzle member provided to face each other, in which a slit as a gas blowing port is formed to extend in a length direction between end portions of the first nozzle member and the second nozzle member on the metal strip side; and a shim member configured to adjust a gap of the slit in a width direction orthogonal to the length direction, wherein the shim member is made of a ceramic material or a carbon material, each of the first nozzle member and the second nozzle member has a groove portion, and the shim member is fitted into both of the groove portions of the first nozzle member and the second nozzle member and fixes the first nozzle member and the second nozzle member.

A Zn—Al—Mg coating on a steel strip. Specific amounts of Mg and Al are chosen, in a relationship wherein the amount of Al is higher than the amount of Mg. Also provided is a method for providing a steel strip having a Zn—Al—Mg coating provided by hot dip coating with a coating bath, wherein the thickness of the coating is controlled using gas knifes above the coating bath.
