Description

Technical Field [0001] The present invention relates to a system for automatically removing dross and sludge from a molten metal,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for automatically removing dross and sludge of a molten metal, and more particularly, to an apparatus for cleaning a dross and a sludge of a molten metal, To a dross and sludge automatic removal system of a molten metal capable of automatically removing dross and sludge.

Generally, a molten metal plating facility is a molten metal facility in which a metal ingot is dissolved in a high-temperature molten state of 450 or more to coat a metal film (for example, zinc, etc.) on the surface of the hot strip, thereby plating the metal film on the surface of the hot strip.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram showing a molten metal installed in a continuous galvanizing line (CGL) according to the prior art; FIG. As shown in Fig. 1, a continuous steel strip 1 is continuously supplied from a uncoiling device (not shown) and connected to a heating furnace (not shown), and a Snout (Snout) 40, which is immersed in a bath surface of the molten metal 10, And the molten metal 20 is introduced into the molten metal 10 through which the molten metal 20 flows. The steel plate 1 is soaked in the molten metal 10 by the immersion roll, that is, the sink roll 50 and the stabilizing roll 60 directly above the molten metal 10, The molten metal 10 is continuously transferred through the molten metal 10 while being vertically changed to the upper portion of the molten metal 10. At this time, the molten metal 20 filled in the molten metal 10 is attached to the surface of the steel plate 1.

Thereafter, the steel plate 1 that has passed through the sink rolls 50 is passed between a pair of stabilizing rolls 60 on the upper side thereof, and its warping is corrected by the operation of the stabilizing roll 60. Thereafter, the steel sheet 1 is passed through an air knife 70 on the upper part of the plating vessel to adjust the surface adhesion amount of the molten metal. Thereafter, the steel sheet 1 is cooled and solidified, and then wound in the form of a coil through a winding device (not shown).

The molten metal plating facility is provided with a plating bath (hereinafter referred to as a " plating bath ") for preventing a temperature difference between the plating bathtub and a vertical strip surface from occurring due to metal oxidation due to contact between the vertical strip surface and the discharge wiping air of a gas wiping device Dross and sludge are generated inside the molten metal.

These drosses and sludges are especially added with various alloy elements such as aluminum, manganese and silicon to improve the corrosion resistance and surface quality of the strip. Oxidation, etc.).

The dross is commonly referred to as a molten metal residue generated by oxidation or the like of the molten metal, and is mostly composed of oxides and nitrides. The sludge is a molten metal residue which is present in the lower part of the molten metal and has a higher viscosity than the dross, and is mainly composed of an intermetallic compound. In particular, the sludge is highly viscous and has a high specific gravity and is deposited on the bottom of the melting furnace, which reduces the volume of the melting furnace during long-time operation of the furnace, thereby reducing the efficiency of recycling.

The dross and the sludge are attached to the inside of the molten metal to reduce the volume of the molten metal and adhere to the surface of the plating layer or the plating surface, thereby causing defects. In addition, it is a major cause of sink roll surface damage and must be removed to improve the cleanliness of the molten metal.

Conventionally, the upper dross suspended above the molten metal was removed by using a receiving plate (shovel). In other words, after the worker collects the upper dross which is lighter than the specific gravity of the molten metal on the upper side of the molten metal to the edge of the molten metal, the accumulated dross is drained by the receiving plate and transferred to the adjacent dross processing box. However, since it has to be manually operated in a hot molten metal, it is difficult to work and it is difficult to effectively remove a large amount of dross quickly.

In addition, the dross and sludge attached to the inside of the molten metal were emptied of the molten metal in the molten metal and then manually removed by the operator using a separate tool. In this way, since the operator manually bends and removes the dross and sludge attached to the inside of the molten metal by using a separate tool, it takes a long time for the work, and the work is difficult and laborious, There was a problem avoiding work.
