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.

A surface temperature measuring method includes: acquiring a radiation light amount of a surface of a measurement object; irradiating the surface of the measurement object with light under a specular reflection condition to acquire a specular reflection light amount; irradiating the surface of the measurement object with light under a diffuse reflection condition to acquire a diffuse reflection light amount; calculating an emissivity of the surface of the measurement object by using a model indicating a relationship between an emissivity and a specular reflectance, and a relationship between the emissivity and a diffuse reflectance of the surface of the measurement object, the acquired specular reflection light amount, and the acquired diffuse reflection light amount; and calculating a surface temperature of the measurement object using the acquired radiation light amount and the calculated emissivity.

A device for coating a metal strip with a liquid coating material comprises a coating container filled with, for example, liquid zinc. After the metal strip exits the coating container, liquid coating material adheres to the metal strip. Excess coating material is blown away from the surface of the metal strip by a blowing device. Thereafter, the metal strip runs through an electromagnetic stabilization device which is supported on the blowing device. Disturbing influences may cause the metal strip to no longer run centrally through a slot of the blowing device. A displacement or re-alignment of the blowing device is then required to guide the metal strip back to the set middle position. A first displacing device displaces the electromagnetic stabilization device relative to the blowing device in the plane transverse to the direction of transport of the metal strip to avoid an undesirable displacement of the electromagnetic stabilization device.

A method and a device for coating a metal strip with a coating material which is at first still liquid. A first displacing device for displacing an electromagnetic stabilisation device relative to a blowing device in the plane transverse to the direction of transport of the metal strip is provided.
