TH47810A - Procedures and equipment for coating hot-dip metal rods, especially steel strips. - Google Patents

Abstract

DC60 (19/04/44) The procedure for hot-dip coating of a steel bar (1), in particular, where the bar (1) is passed vertically through a container holding the molten coating and through a pilot channel leading to the source (2). The electromagnetic field of the moving wave in the coating induces an induced current, which interacts with the electromagnetic field of the moving wave to generate an electromagnetic force for holding the coating. This is performed with the aim of continuously correcting the electromagnetic field perpendicular to the surface of the bar (1a) in order to stabilize the center position of the bar (1) in the pilot channel (2) or inductor (3).

Claims (10)

1. The process for hot-dip coating metal rods, specifically steel strips, involves the rod being passed vertically through a container holding the molten coating and through a guide channel. The electromagnetic field of the moving wave within the coating induces an induced current, which interacts with the electromagnetic field of the moving wave to generate an electromagnetic force that holds the coating in place. This force is unique because the electromagnetic field is continuously modified to be perpendicular to the surface of the rod, stabilizing the rod's center position in the guide channel or inductor. 2. The procedure under claim 1 is characterized by the fact that the electromagnetic field is modified in a way that generates an S-shape perpendicular to the direction of motion in the metal rod. 3. The procedure, according to one of the claims 1 or 2, is characterized by the fact that the rectifying coil is operated in balance with the magnetic field of the inductor's moving wave, utilizing fluid dynamics and magnetic forces. 4. A device for hot-dip coating of metal bars, specifically steel bars, in which the metal bar is passed vertically through a container holding the molten coating and through a pilot channel leading to the source, where the electromagnetic field of the moving wave in the coating induces an induced current, which interacts with the electromagnetic field of the moving wave to generate an electromagnetic force for holding the coating. This is made special by the fact that a rectification coil (5) is incorporated into the magnetic yoke (7) of the main coil (6) of the inductor using fluid dynamics and magnetic force (3). 5. The device, according to claim 4, is made special by the fact that at least two rows (8) of smaller modifier coils (5) are arranged along the path of the metal rod (1c) to create a progressive characteristic of the higher-order metal rod characteristic curve in a direction perpendicular to the longitudinal direction of the metal rod (1b). 6. The device under claim 5 is made special by the fact that each smaller (5) rectifier coil is actuated by 7. The device, according to one of the claims 4 through 6, is made special by the fact that the position of the metal rod (1) in the pilot channel (2) can be measured for each individual correction process. 8. The device, according to one of the claims 4 through 7, is made special by the fact that it is able to modify the modified coil (5) using the control circuit. 9. The device under claim 8 is made special by the fact that a separate control circuit is allocated to each rectifier coil (5). 10. The device, according to one of the claims 4 through 9, is made special by the fact that more than two electromagnetic fixing coils (5) are arranged, each of which is in at least two rows (8) of fixing coils (5) along the path of movement of the metal rod (1c).
