Problems solved by technology

With today's stabilizers this is not possible as space must be provided for the plate to vibrate between the air knives which causes the coating thickness to become greater than necessary
Thick coatings result in a more expensive product compared to thin coatings and also result in surface defects such as uneven coating

Embodiment Construction

[0035] Figure 1 shows an apparatus for stabilizing an elongated metal strip 1 as it is continuously conveyed through a molten metal plating tank 2 in a vessel 3 to coat the strip.

[0036] The device comprises a wiping device 4 for wiping off excess molten metal from the strip by applying a stream of air to the metal strip, and the wiping device comprises at least a first pair of air knives 5 , 6. The pair of air knives includes one air knife on each side of the strip 1 . The air knives 5, 6 are arranged at the beams 19, 20 by means of suspension devices 21, 22 and since the beams are arranged movable in vertical and horizontal directions, the position of the air knives can be adjusted relative to the position of the strip 1 . The device also comprises an electromagnetic stabilizing device 7 arranged to stabilize the position of the strip relative to the predetermined transport path x. The electromagnetic stabilizing device 7 comprises at least one first pair of electromagne...

Abstract

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).

Description

technical field [0001] The present invention relates to an apparatus for stabilizing an elongated metal object of magnetic material as it is coated with a metal layer by continuously conveying the object through a molten metal plating tank. The metal object is to be conveyed from the device in a conveying direction along a predetermined conveying path. The apparatus includes wiping apparatus for wiping excess molten metal from the metal object by applying a stream of air to the object, and the wiping apparatus includes at least a first pair of air knives positioned between the An air knife is included on each side of the object. The apparatus also includes an electromagnetic stabilizing device arranged to stabilize the position of the object relative to the predetermined transport path, the electromagnetic stabilizing device comprising at each side of the plane at least one first pair of electromagnetic stabilizing members. [0002] The invention also relates to a method for...
