摘要： The weight and distribution of the coating material applied to a moving steel strip, extracted from a bath of molten zinc, are advantageously controlled by combined action of magnetic forces that are induced in a layer of coating by means of a non- continuous magnetic field and a jet of gas. The synergistic effect of the electromagnetic forces and the jet of gas enables removal of the coating material in excess, prevention of a premature solidification of the coating layer in the area of impact of the gas, and prevention at the same time of any oscillation of the strip. Thanks to the jointed action of the magnetic forces and of the gas jets a uniform coating is obtained.

摘要： The invention relates to a method for the hot dip coating of a metal strip (1), in particular a steel strip, according to which the metal strip (1) is fed vertically through a container (3) that holds the molten coating metal (2) and a guide channel (4) that is connected upstream. According to the invention, to retain the coating metal (2) in the container (3) in the vicinity of the guide channel (4), an electromagnetic field is generated by means of at least two inductors (5) that are situated on either side of the metal strip (1) and to stabilise the metal strip (1) in a central position in the guide channel (4), the electromagnetic excitation of the inductors (5) is modified and/or an electromagnetic field that overlaps the electromagnetic field of the inductors (5) is generated by means of at least two correction coils (6) that are situated on either side of the metal strip (1). The aim of the invention is to control the centring of the metal strip in a manner that is not susceptible to interference. To achieve this, the stabilisation of the central position of the metal strip (1) in the guide channel (4) takes place in a closed-loop control circuit by the sequence of the following steps: a) measurement of the force (FH) that acts in a horizontal direction and that the metal strip (1) exerts on a force measuring element (7) when it leaves the central position; b) the induction current (II) in the inductors (5) and/or on the induction current (II) in the correction coils (6) is influenced in accordance with the measured force (FH), in order to hold the metal strip (1) in a central position in the guide channel (4). The invention also relates to a device for the hot dip coating of a metal strip.

摘要： A device and a method for stabilizing an elongated metallic strip of a magnetic material when coating the strip (1) with a metallic layer. The strip is transported from the bath (2) in a direction of transport (16) along a predetermined transport path (x). A wiping device (4) for wiping off superfluous molten metal from the strip (1) applies an air flow in a line across the strip (1), where the wiping device (4) comprises at least one pair of air-knives (5, 6) arranged with one air-knife on each side of the strip (1). An electromagnetic stabilizing device (7) stabilizes the position of the strip (1) with respect to the predetermined transport path (x). A sensor (14, 15) detects the position of the strip (1) in relation to the predetermined transport path (x).

摘要： A method for producing a Zn-Al-Mg base hot dip steel sheet excellent in retention of gloss, which comprises appropriately controlling, in a step of cooling with water after coagulation of a plating layer, "the temperature at which the plating layer is contacted with water flow", that is, appropriately controlling in the step "the temperature of a material to be plated when it is contacted with water flow", and preferably using a plating bath having a small amount of "an highly oxidizable element" incorporated therein. The employment of the method stabilizes the oxidation states of Al and Mg present in the surface portion of the plating layer, which results in the suppression of deterioration in the surface gloss of a Zn-Al-Mg base hot dip steel sheet.

摘要： The invention relates to a device for hot dip coating metal strands (1), particularly strip steel, in which the metal strand (1) can be vertically guided through a reservoir (3), which accommodates the molten coating metal (2), and though a guide channel (4) connected upstream therefrom. An electromagnetic inductor (5) is mounted in the area of the guide channel (4) and in order to retain the coating metal (2) inside the reservoir (3), can induce induction currents in the coating metal (2) by means of an electromagnetic traveling field. While interacting with the electromagnetic traveling field, said induction currents exert an electromagnetic force. The inductor (5) has at least two main coils (6) that are arranged in succession in movement direction (X) of the metal strand (1), and has at least two correction coils (7) for controlling the position of the metal strand (1) inside the guide channel (4) in direction (N), which is normal to the surface of the metal strand (1). These correction coils are also arranged in succession in movement direction (X) of the metal strand (1). In order to improve the efficiency of the control of the metal strip inside the guide channel, the invention provides that at least a portion of the correction coils (7), when viewed in movement direction (X) of the metal strand (1), are arranged so that they are offset with regard to one another perpendicular to movement direction (X) and perpendicular to direction (N) that is normal to the surface of the metal strand (1).
