れ始めている。 The greater the thickness of the plating, the better the corrosion resistance of a plated steel plate, but for steel plates for automobiles that are painted after plating, if the plated surface is painted, the sharpness will be poor and the commercial value will be significantly reduced. Further, for example, the weldability of galvanized steel sheets is unfavorable because the difference between the melting point and boiling point of zinc is small, the thermal conductivity is good, and the electrodes are easily contaminated.
In this way, corrosion resistance has properties that conflict with weldability and image clarity after painting, so steel sheets for automobiles,
Steel plates for home appliances are plated on only one side,
So-called single-sided galvanized steel sheets have begun to be used, which have corrosion resistance on one side and improved paintability and weldability on the other side.

る。 As a method for manufacturing this single-sided plated steel sheet, there is a method using electroplating, but the plating thickness of the plating layer obtained by the electroplating method is generally small and it is not possible to provide sufficient corrosion resistance. In order to produce products with a large amount of plating using the electroplating method, it is necessary to reduce the threading speed, resulting in poor productivity and high costs.

点があつた。 On the other hand, with the melt plating method, a large amount of plating can be easily obtained. One way to produce single-sided plated steel sheets using the hot-dip plating method is to apply phosphate treatment to one side and then plate the plate (Japanese Patent Publication No. 1973-
24966), the method of applying water glass to one side to prevent plating (Special Publications No. 39-7112, 39-4522), and the method of applying various other lubricants (for example, the method of applying various coating agents)
35174 and 51-8101) are known. However, when these methods are applied to Sendzimer-type continuous plating equipment that performs pretreatment by heat treatment immediately before plating, the steel strip is exposed to high temperatures of about 700°C, so treatment agents such as phosphates and water glass are used. Due to alteration and decomposition, it has been difficult to reliably produce single-sided plated steel sheets. Furthermore, it is necessary to apply an expensive treatment material to the non-plated surface, and special materials and machines are required to remove the treatment coating after plating, resulting in an increase in plating costs.

る。 The present invention was made based on the fact that when the surface of a material to be plated is coated with soot as a pretreatment, the plating solution does not adhere to the part covered with the soot film. The feature of this method is that after coating the non-plated surface of the material to be plated, the material is immersed in molten plating metal to adhere the plating metal to the plated surface. This is a one-sided plating method in which soot is deposited by passing a combusted flame through the metal, and then the material to be plated is immersed in molten metal.

ことができ片面メツキ鋼板が得られる。 FIG. 1 shows an embodiment in which the present invention is applied to a Sendzimer type continuous plating device. Fuel is incompletely combusted by a burner 3 installed in a snout 2 on one side of the steel strip 1, which has been subjected to gas cleaning treatment and its surface has been activated by a pretreatment device (not shown), and the generated combustion products are removed from this non-plated surface. Attach it to the surface.
In order to achieve incomplete combustion of the fuel, the amounts of fuel and air supplied from the fuel supply pipe 4 and the air supply pipe 5 may be appropriately adjusted by the respective flow rate control valves 6 and 7. In other words, incomplete combustion can be easily achieved by supplying an amount of air that is smaller than the theoretical amount of air required to completely burn a fixed amount of fuel. In this case, it is also possible to control the amount of soot generated depending on the passing speed of the material to be plated. FIG. 2 is a cross-sectional view taken from FIG. 1, and the burner 3 is equipped with fuel outlets 8 arranged at regular intervals. The fuel blown out from the fuel outlet 8 undergoes incomplete combustion due to the lack of supplied air, generating soot as a combustion product, and only one side B of the steel strip 1 is coated with soot 9 having a uniform width.
When the steel strip 1 whose one side B is coated with soot, which is a combustion product, is passed through the plating metal 11 of the plating tank 10, the activated surface A to be plated which is not coated with soot is not plated. Although metal adheres to it,
No plating metal adheres to the soot-covered surface B, making it a non-plated surface. A single-sided plated steel plate is obtained by controlling this to a desired coating amount by squeezing it with a plated roll 12. When the steel plate leaves the plating tank, it can be brushed with a commonly used brush roller to easily remove soot adhering to the non-plated side, resulting in a single-sided plated steel plate.

層確実となる。 Figure 3 shows an example of an apparatus for removing soot attached to the non-plated side of a steel strip whose one side has been unplated by the method described above.
After being cooled by the cooling device 13, the soot on the non-plated surface side is removed by the brush roller 14.
The soot on the non-plated side also has the role of preventing oxidation of the steel strip after plating treatment (the plating side does not oxidize because it is covered with plating metal), so there is no need to take special oxidation prevention measures. It also has advantages.
When removing soot with the brush roller 14, if water is jetted from the spray nozzle 15, the removal of the soot becomes more reliable.

増加させることが出来ることは明らかである。 FIG. 4 shows an embodiment in which the present invention is applied to a Wheeling continuous plating method, which is a typical type of off-line annealing method. The unplated surface of the steel strip 1, whose surface has been cleaned by the degreasing device 16 and the pickling tank 17, is coated with soot by the burner 31. Next, the steel sheet enters the flux treatment device 18, and after drying the flux and preheating the steel sheet at the same time in the drying preheating furnace 19, the steel sheet is placed in the plating tank 10 to obtain a steel strip with one side unplated. A single-sided plated steel strip is obtained by removing soot from this using a brush roller in the same manner as described above. Covering soot with burner 31〓〓〓〓〓
It is clear that a plurality of similar burners 32 can be provided to increase the coverage.

とが確認された。 According to experiments conducted by the present inventors, acetylene gas was incompletely combusted in a burner on a steel strip that had been gas-purified by the method illustrated in Fig. 1, soot was deposited on one side of the steel strip, and the galvanizing bath temperature was 460°C. A beautiful single-sided plated steel plate with a zinc coating of 213 g/m 2 on one side was obtained. Soot on the unplated surface could be easily removed using a nylon brush at a circumferential speed of 20 m/sec. Next, 24 for the mated surface.
As a result of an hourly salt spray test, it was confirmed that there was no red rust on the plating surface, and reliable plating was performed.
