Embodiment Construction

[0063] Figure 1 shows an embodiment of a system for coating flat metal articles using continuous hot dipping in a bath of molten metal. Such a system includes:

[0064] The electromagnetic equipment 1 targeted by the present invention, also known as a galvanizer when the coating is zinc, comprises an inductor 3 and a container 11 containing a bath of molten metal;

[0065] - a current feeder 2 for feeding the inductor 3 in the vicinity of the wound coil 4;

[0066] - a heating / melting kiln 5 provided with a circulation pump 6 installed in the hearth so as to be intruded into the molten bed material in the kiln;

[0067] - a suitably heated sediment filter 7 for purifying molten paint material;

[0068] - Suitably heated pipes for circulating molten layer material from the galvanizer 1 to the furnace 5, from the furnace 5 to the sediment filter 7 and finally from the sediment filter 7 back to the galvanizer 1 8.

[0069] - Closing mechanism 10 for closing the container 11 in...

Abstract

An electromagnetic device for coating flat metal products by means of continuous hot dipping in a small molten coating bath, arranged over strip guiding rollers, the device being adapted not only to contain the molten coating metal in the bath but further to substantially eliminate leakages and dripping through the lower opening at the bottom of the container, for the strip passing, by means of particular electromagnetic components.

Description

Technical field: [0001] The invention relates to an electromagnetic device for coating flat metal articles, such as steel strip, with a coating metal, such as zinc or a zinc alloy, by continuous hot dipping, and also to flat metal Product continuous hot dip coating process. Background technique: [0002] The known steel strip coating process involves passing it vertically through a bath of molten metal kept semi-suspended by means of an alternating magnetic field. [0003] The traditional hot-dip galvanizing process is continuous and usually requires (as an initial stage) to pre-treat and preheat the strip before coating it with careful control of its temperature. Pretreatment chemically and thermally to improve the adhesion of the coating on the strip, the heat treatment stage may be a preheating operation in a controlled atmosphere or a melting operation in which the strip is immersed in a reducing inorganic flux In order to form a protective film on the surface of the s...
