    摘要: The invention specifies a method which allows process-stable hot-dip coating of Ni-alloy steel flat products in a cost- and resource-effective manner, comprising the following steps: a) provision of a steel flat product obtained by cold- or hot-rolling, b) within 1-30 s, heating the steel flat product to a holding temperature between 700 and 1100° C., under a heating atmosphere of N2; c) holding the steel flat product at the holding temperature for a holding duration of 10-120 s under a holding atmosphere of N2; d) cooling the steel flat product from the holding temperature to a strip inlet temperature of 430-800° C.; e) passing the steel flat product through an inlet zone, in which an inert or reducing inlet atmosphere predominates, and passing the steel flat product through a melt bath, wherein TP1>TP2>TP4.

    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: 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.
