Abstract

DC60 (14/05/47) This invention involves a method for hot-dip coating of metallic strands (1), in particular, of a steel strip in which the metal strands (1) are directed vertically through the container. (3) which makes it suitable To the metal used for the molten coating (2) and through the conductive channel (4) with the height (H) determined by which in order to preserve the metal used for the coating (2) in the container (3) A magnetic field is generated in the area of the guide channel (4) by means of at least two conductors (5) placed on both sides of the metal line (1) in order to make The basin for the glaze was smooth, without waves, the preparation was performed in accordance with this invention. For a predetermined flow volume (Q) in the area of elongation with its height (H) this invention Further related to equipment for Hot Dip Coating of Metal Strands The invention involves a method for hot-dip coating of metallic strands (1), in particular of the steel strip, in which the metal strands (1) are directed vertically through the container.

Claims (10)

1. A method for hot-dip coating of metals (1), specifically of steel strips, in which a metal wire (1) is brought vertically through a container (3) which is fitted with the molten coating metal (2) and through a conduction channel (4) of a specified height (H), in order to keep the coating metal (2) in the shape of (3), an electromagnetic field is created in the area of the conduction channel (4) by means of at least two conductors (5) placed on either side of the metal wire (1) such that a predetermined flow volume (Q) of the coating metal (2) is introduced into the conduction channel (4) in the area of extension of height (H). 2. A method in accordance with claim 1 is characterized as follows: the predetermined flow volume (Q) of the coating metal (2) being introduced into the guide channel (4) is consistent per unit time per fraction of the volume of re-filling of the coating metal (2) determined in order to maintain the desired height (h) of the coating metal (2) in the container (3). 3. The method in accordance with claim 1 is characterized as follows: the predetermined flow volume (Q) of coating metal (2) introduced into the intake channel (4) corresponds per unit time to the total new filling volume of coating metal (2) determined in order to maintain the desired level (h) of coating metal (2) in the container (3). 4. The method in accordance with claims 1 to 3 is characterized by the predetermined flow volume (Q) of the metal used for coating (2), which is directed to the guide channel (4), being directed in a controlled or organized manner. 5.
