Definitions
- the subject of the present invention is a method and a device for continuously coating a steel strip using a liquid metal, in particular zinc, zinc-aluminum or aluminum.
- the present invention is particularly suitable for continuous hot-dip galvanizing.
- the steel strip is immersed in the bath of liquid metal contained in a crucible and the path of said strip in the crucible is about 2.50 meters.
- the iron of the strip is attacked by the bath of liquid metal and dissolves in said bath.
- iron reacts with the elements of the bath to form solid intermetallic compounds in the form of particles, zinc-iron, zinc-iron-aluminum, or zincaluminium in the case of hot-dip galvanization.
- These particles have a size ranging from a few microns to several hundred microns depending on the degree of saturation of the bath. Given the continuous stirring of the bath and according to their density and composition, these particles rise to the surface, or remain in saturation or even settle at the bottom of the bath. Consequently, the particles can be entrained by the strip and remain included in the coating. However, the inclusions of particles are detrimental to the surface appearance and to the use of hot-dip galvanized sheet, in particular for visible parts of the automobile body.
- the large volume of the crucible has the drawback of making it difficult to purify the bath by filtration and of increasing the time necessary for any change in the composition of said bath.
- the present invention aims to avoid these drawbacks and has the particular advantage of being able to continuously filter the entire bath after pollution on contact with the strip, while allowing rapid corrections to the composition of the bath.

- the auxiliary crucible 11 also includes a hopper 20 to correct the quality of the liquid metal contained in said crucible 11, for example by the addition of elements such as, for example, aluminum, lead, or bismuth.
- the pinch rollers 7 and 8 include a coating resistant to thermal stresses and not wetted by the liquid metal and are provided with wiping members, not shown, for example with nitrogen for preventing entrainment of liquid metal on the surface of said rollers.
- the coating of the pinch rollers 7 and 8 may consist of a thin ceramic coating on steel, or a coating of non-porous and non-cracked molybdenum on steel.
- Pinch rollers 7 and 8 can also be formed by ferrule rollers in silica or ceramic.
- pinch rollers 7 and 8 may also include internal heating means, not shown, constituted for example by electric heating candles or a gas radiant tube, to minimize thermal stresses.
- the horizontal axes of the pinch rollers 7 and 8 can be offset vertically relative to each other to avoid bending the steel strip 2 as it passes around one of the rollers and in the nip interval of said rollers.
- Wringing means formed, for example by ramps 21 placed on either side of the steel strip 2, are arranged about one meter above the coating area 10.
- the steel strip 2 is wrung pneumatically under nitrogen with recirculation.
- two pads 22 are applied for example by jacks 23 in said interval at an adjustable distance from the edge of the strip d steel 2.
- pads 22 can be graphite or amorphous carbon or consist of compacted fibrous ceramic materials or organic materials resistant to high temperatures (up to 500 ° C) under nitrogen protection.
- the coating device also includes means for recovering and recycling the excess liquid metal flowing through the nip 9 of the rollers 7 and 8.
- These means consist of a retention tank 25 made of refractory material disposed below said nip interval 9 and the bottom of which comprises two orifices 26a which can be closed alternately by a buffer nozzle 26.
- each orifice 26a is placed a recovery crucible 27 each provided with heating means 28, for example by induction, and possibly with a filter 29.
- Each crucible 27 is connected by a funnel 30 to the main crucible 3.
- the liquid metal returns directly to the main crucible.
- each recovery crucible 27 is provided with means 31 for detecting the overflow of the liquid metal of said crucible formed for example by a photoelectric cell targeting the overflow spout 27a of the corresponding crucible (FIG. 1).
- the coating device according to the invention operates in the following manner.
- the main crucible 3 is filled with liquid metal, in particular pure zinc without aluminum or lead, the liquid metal being maintained at the desired temperature by the heating means.
- the pump 14 transfers the liquid metal via the line 13 into the auxiliary crucible 11 where it is maintained at the desired temperature by the heating means 12.
- the liquid metal in particular zinc
- the liquid metal can be corrected by additions to the hopper, for example aluminum, lead or bismuth.
