A dross removal device including: a dross robot that is configured to collect a bath surface dross present on a bath surface of a coating bath; a dross sensor that is configured to measure an intensity of infrared light from the bath surface of the coating bath; a dross sensor control device that is configured to specify a position of the bath surface dross according to a temporal change amount in the intensity of the infrared light; and a dross robot control device that is configured to cause the dross robot to collect the bath surface dross at the position specified by the dross sensor control device.

A rectangular parallelepiped ingot defined by a height H, a width W and a length L, having longitudinal faces extending between two end faces, having a volume between 0.15 m.sup.3 and 0.80 m.sup.3 and a surface area to volume ratio between 10 m.sup.?1 and 18 m.sup.?1, made of at least one metal, including at least one notch and a notch tip along the ingot length, wherein the at least one notch is configured such that: MaxD<H/2, MaxD<W/2 and MaxD being the maximum distance between any point of the ingot and the closest surface of the ingot.

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.

Disclosed is a device for removing mattes from the surface of a liquid metal bath inside a duct of a line for continuously coating a metal strip having first and second faces, the first face being intended to come into contact with a bottom roller, comprising a compartment via which the liquid metal inside the duct is replenished by being drawn off by a pump to which the compartment is connected, characterized in that the compartment is capable of being removed by disassembly means without the metal strip needing to be cut.

Equipment for the continuous hot dip-coating of a metal strip 9 including an annealing furnace, a tank 2 containing a liquid metal bath 3, a snout connecting the annealing furnace and tank 2, through which the metal strip 9 runs in a protective atmosphere and the lower part of the snout, the sabot 5, is at least partly immersed in the liquid metal bath 3 in order to define with the surface of the bath, and inside this snout, a liquid seal 6, an overflow 7 not connected to the snout, the overflow 7 including at least one tray 8, placed in the vicinity of the strip 9 when entering the liquid metal bath 3 and encompassed by liquid seal 6.

A coated stainless-steel substrate including a coating including nanographites and a binder being sodium silicate, wherein the stainless-steel substrate has the following composition in weight percent: C1.2%, Cr11.0%, Ni8.0% and on a purely optional basis, one or more elements such as Nb6.0%, B1.0%, Ti3.0%, Cu5.0%, Co3.0%, N1.0%, V3.0%, Si4.0%, Mn5.0%, P0.5%, S0.5%, Mo6.0%, Ce1.0%, the remainder of the composition being made of iron and inevitable impurities resulting from the elaboration. A method for the manufacture of this coated stainless-steel substrate is also provided.

An equipment for the continuous hot dip-coating of a metallic strip comprising: an annealing furnace, a tank containing a liquid metal bath, a snout connecting the annealing furnace and said bath, through which the metallic strip runs in a protective atmosphere and the lower part of said snout, the snout tip, is at least partly immersed in the liquid metal bath in order to define with the surface of the bath, and inside this snout, a liquid seal, a moveable support system, on at least one tank side, comprising connecting means, an overflow connected to said moveable support system through said connecting means, comprising at least one vat and at a least one pump.
