Al is applied to one side of the
The present invention relates to a hot-dip aluminized steel sheet in which a -S in is formed, respectively, and is suitable for a wide range of uses. [Prior Art] Galvanized steel sheets have been used for a long time as steel sheets with improved corrosion resistance and weather resistance because they are easy to manufacture and inexpensive, but they are not sufficient in both corrosion resistance and weather resistance. Since then, aluminum-plated steel sheets have come to be used depending on the application. Aluminized steel sheets are generally manufactured using a continuous hot-dip aluminum plating method.In principle, the steel sheets are heated in a mildly oxidizing atmosphere to remove the rust preventive oil and rolling oil that have adhered to the surface, and then heated in a reducing atmosphere. It is manufactured by continuously passing a raw steel sheet that has been heated and reduced through an aluminum bath, and then adjusting the amount of plating deposited by gas wiping or the like. Aluminum plating baths typically contain 5 to 11% Si to reduce the growth of a hard and brittle alloy layer of Fe and Al. FIG. 3 is an explanatory cross-sectional view of a conventional 71J aluminized steel sheet obtained in this manner. As shown in FIG. 3, this conventional hot-dip aluminized steel plate 5 has "e
F, which is an alloy of 8σ and 8σ, which has a strong affinity with this.
An e-Al-Si alloy layer 3 is formed, and Al-8ii 14 is further formed on the outer side thereof. Since the Al-Sili 4 formed on the outside is mainly composed of Al, which has a strong affinity for oxygen, it is covered with a dense oxide film that has high corrosion resistance and weather resistance in the air. As described above, the conventional hot-dip aluminized steel sheet 5 had Al-SiG4 formed on its circular outer surface, and had much better corrosion resistance and weather resistance than the galvanized steel sheet.

狭い問題点があった。However, although such conventional hot-dip aluminized steel sheets 5 have good corrosion resistance and weather resistance as described above, on the other hand, the same Si material deteriorates weldability and paintability, so it is difficult to weld. In many cases, it cannot be used in cases where paint or paint is required, and furthermore, the moisture corrosion resistance required for automobile mufflers is insufficient, resulting in the problem that the scope of use is extremely narrow.

A Fe-Al-Si alloy decoy with a thickness of 3 to 10 μm is formed on one side of a steel plate having a composition consisting of diiron and unavoidable impurities, and Al-stl is further formed on the outside of the decoy. Fe-Al-S with a thickness of 3 to 10μ on one side of
The present invention relates to a hot-dip aluminum-plated steel sheet characterized by having an i-based alloy layer formed thereon. EMBODIMENT OF THE INVENTION Hereinafter, the hot-dip aluminum plated steel sheet (hereinafter sometimes abbreviated as the present invention plated steel sheet) and the manufacturing method thereof according to the present invention will be explained in detail with reference to the drawings. FIG. 1 is an explanatory cross-sectional view of a hot-dip aluminized steel sheet according to the present invention, and FIG. 2 is an explanatory view of a method for manufacturing a hot-dip aluminized steel sheet according to the present invention. [Description of the plated steel sheet of the present invention] The first feature of the plated steel sheet 1 of the present invention is that, as shown in FIG. Additionally, Al-s is added to the outside.
v4 is formed, and the Fe-Al-Si alloy layer 3 is formed on the other side. In other words, compared to the conventional hot-dip aluminized steel sheet 5,
The biggest difference is that the Al-st layer 4 is formed on only one side, and the Fe-Al-Si alloy layer 3 is exposed on the other side. The second feature of the plated steel sheet 1 of the present invention is that the thickness of the Fc-Al-Si alloy layer 3 is limited to 3 to 10 microns. The reason for this is that, as will be described later, in the plated steel sheet 1 of the present invention, the Fe-Al-8i alloy layer 3 is exposed on one side, resulting in good weldability, paintability, high moisture corrosion resistance, etc. On the other hand, if the thickness of the Fe-Al-Si alloy straddle 3 is too thick, processing such as drawing becomes difficult. Therefore, as a result of examining the thickness of the Fe-Si alloy layer 3 that would not cause such difficulties and solve the above-mentioned problems, it was determined to be 3 to 10 .mu.m. Al-5i
The thickness of the layer 4 can be set depending on the degree of corrosion resistance and weather resistance required for each application. The third feature of the plated steel sheet 1 of the present invention is that the base material W42 forming the main body thereof has a C:≦0.01%, Mn: 0.10~
0.40%, Ti: 0.04-0.30%, C
r: 50.30%, ■ji/'(C+N)>4. The remainder consists of diiron and unavoidable impurities. For the following reasons, when steel sheets with this composition are subjected to hot-dip aluminum plating, compared to rimmed steel sheets, which are the raw steel sheets for conventional hot-dip aluminized steel sheets, the Fe-^a-sr alloy layer 3 forms and grows very quickly. This is because the steel plate's b1 mechanical properties, solid solute C and N are fixed by (1), and are therefore extremely excellent. ■ Steel sheets with the above composition have a higher recrystallization temperature than rimmed steel sheets, and it is necessary to increase the heating temperature before plating.For this reason, the steel sheets are introduced into the aluminum plating bath in a high n state, so Fe-8 -Si-based alloy threshold is likely to be generated. (2) Since free Ti (Ti that has not become a compound such as TiC or TiN) is present in the steel sheet having the above composition, Al diffuses easily into Fe, and a Fe-Al-8i alloy layer is likely to be formed. [Method for producing plated steel sheet according to the present invention 1] As shown in FIG. 2, a raw steel sheet 1' which has been pretreated according to the usual hot-dip aluminum plating method is first introduced into an aluminum bath 6. Pretreatment is generally performed as follows. In other words, the raw steel sheet 1'
A condition in which rust preventive oil and rolling oil adhering to the front and back surfaces of the steel are removed by evaporation or chemical reaction, and then introduced into a reducing atmosphere furnace to remove the oxide film formed in the previous process so that Fe and Al are in close contact with each other. The material is prepared and annealed, and then heated to a temperature of 550 to 850 degrees Celsius and introduced into the aluminum bath 6 through a conduit 7 without being exposed to the outside air. As mentioned above, this aluminum bath usually has 5 to 1196
of Si is contained. The raw steel plate 1' introduced into the aluminum bath 6 is changed direction by a pot roll 8 and pulled upward, and the amount of plating is first adjusted by gas wipers 9, 9'. In this case, on one side of the raw steel plate 1', Fe-Al-Si
The hot-dipped metal that will become the final Al-Si layer is prepared by leaving the alloy layer on top of it. The gas wiping conditions of the gas wiping nozzle 9 and the gas wiping nozzle 9' for thick coating, such as gas pressure, gas temperature, nozzle height, and nozzle spacing, are adjusted respectively.As an example of differential pressure coating, thin coating is 30
(1/m' or less, and 800/m2 or more for thicker areas.The hot-dip plated steel sheet 1 whose plating level has been adjusted to have a differential pressure area is brushed as necessary for thin areas. The roll 10 and the brushing roll 10' for thick coating remove unnecessary coatings and adjust the plating thickness, and if necessary, the surface on the thin coating side is heated with a heater 11.
to complete the layering of the Fe-Al-Si alloy up to the surface of this surface, smooth the surface irregularities caused by the brushing roll 10, and finally form the Fe-Al-Si alloy between the outermost surfaces of one side. In addition to forming a cabinet, each layer is made to have a predetermined thickness. To that extent, either or both of the brushing roll 10, 10' and the heater 11 may not be used. After that, it is cooled and smoothed with a leveler. Perform normal post-treatments such as chemical conversion treatment on the plating surface. [Operations and Effects] The hot-dip aluminized steel sheet according to the present invention has a Fe-Al-Si alloy layer on one side of a steel sheet with a specific composition, which has a maximum thickness of 4μ, which is the thickness of a conventional hot-dip aluminized steel sheet. A Fe-^a-S;-based alloy layer with a thickness of 3 to 10 μm is formed, and an Al-Si layer is formed on the outside of the Fe-^a-S alloy layer.
A layer is formed on the other side, and the thickness is 3 to 10μ, which is much thicker than the maximum thickness of 4μ, which is the thickness of the Fe-to-Si alloy layer of conventional hot-dip aluminized steel sheets.
Since the Fe-Al-Si alloy layer is formed, it can be used in various ways. For example, in applications where corrosion resistance and weather resistance are important, Al-Si
For applications where paintability is important, use the surface on which the decoy is formed, use the surface on which the Fe-Al-Si alloy layer is formed on the outside, and when welding, use the surface on which the Fe-Al-Si alloy layer is formed. -8
By welding the side on which the i-based alloy circle is formed, it is possible to exhibit unique characteristics in each application. Historically, Fe-Al-Si alloy layers have high moisture corrosion resistance in alkaline atmospheres such as automobile mufflers, so ^Q-8
If used in an automobile muffler with the i-layer on the outside and the Fe-Al-Si alloy layer on the inside, the life of the muffler will be greatly extended because both the outside and inside surfaces have great resistance to the respective environments, and the demand for it will increase. Very large. The present invention as described above greatly contributes to the development of industry.
