摘要： The invention relates to a device and a method for hot-dip coating a metal strip with a metal covering, wherein the metal strip is directed continuously through a melt bath, wherein the thickness of the metal covering present on the metal strip when it leaves the melt bath is adjusted by means of a scraping device, and wherein slag which is present on the melt bath is driven away from the metal strip leaving the melt bath by means of a gas flow. To prevent slag from coming into contact with the metal strip leaving the melt bath, the invention drives away the slag from the metal strip by means of at least one nozzle which is arranged in close proximity to the metal strip, that a gas flow which extends over the width of the metal strip is directed onto the surface of the melt bath.

摘要： Devices and methods for cleaning a roller of a system for processing strip-type material may involve a suction duct in addition to a nozzle that directs a gas flow onto a surface of the roller. The nozzle and the suction duct may be disposed in a hood that covers part of a circumference of the roller. Further, the nozzle can be disposed at an angle within a range of ±45 degrees with respect to a normal line extending orthogonally from the surface of the roller. Moreover, the nozzle may be spaced less than 50 mm apart from the surface of the roller.

摘要： The invention relates to a device for strip guidance in a hot medium, comprising a deflection roller (3, 38) mounted on supporting arms (1, 2, 34, 37, 54, 57) and a carrier device holding the supporting arms (1, 2, 34, 37, 54, 57). The device is characterized in that one of the supporting arms (1, 2, 34, 37, 54, 57) is mounted on the carrier device by means of a floating bearing (5), wherein the floating bearing (5) allows the mounted supporting arm on the carrier device to move parallel to the longitudinal direction of the deflection roller (3, 38), and in that an elastic counter element (12), which acts parallel to the longitudinal direction of the deflection roller (3, 38) upon the supporting arm (1, 2, 34, 37, 54, 57) mounted on the floating bearing (5), is present and counteracts an increasing distance between the supporting arms (1, 2, 34, 37, 54, 57). In this way, the technical problems of offsetting a temperature-induced length change of the deflection roller and avoiding an uncontrolled movement of the system are solved.

摘要： A steel product may include a metallic anticorrosion coating of an aluminum alloy. So that such a steel product possesses high media resistance, more particularly high acid resistance and corrosion resistance, the steel product may be immersed in a liquid-melt coating bath that includes an aluminum alloy. In addition to Aluminum and unavoidable impurities, the aluminum alloy may include at least one of 0.2-2% by weight Mn or 0.2-7% by weight Mg, 0.5-5% by weight Fe, and at least one of 0.05-0.4% by weight Ti or 0.05-0.4% by weight Zr. A method for producing such steel products may involve providing a steel product in a hot-rolled or cold-rolled state, activating a surface of the steel product to remove passive oxides, and coating the surface-activated steel product by immersion in a liquid-melt coating bath that comprises an aluminum alloy having the aforementioned composition.
