コストの上昇の問題があった。As a material for food cans, tin-plated steel sheets, commonly referred to as yellowtail, have been widely used1. In the past, solder was used to join these can bodies, but due to problems with the 1U nature of lead contained in solder, pure tin solder has come to be used in recent years. [7]However, there are technical problems with solder joints because pure tin solder has inferior properties when joining, and there is also the problem of increased manufacturing costs due to the use of expensive pure tin solder.

できないことが判明した。The inventors have conducted various studies on the weldability and paint corrosion resistance of the above-mentioned materials for welded cans, especially those with thin coatings, and have found that weldability is good unless the amount of chromium water-retaining oxide film exceeds a certain value. It has been found that corrosion resistance is poor in this region, and although corrosion resistance improves when the total amount of chromium water-retaining oxide film is increased, weldability deteriorates, making it impossible to obtain an appropriate welding range. That is, from the point of view of economy, there is a limit such as 12/d or less. Within the range of tin adhesion, weldability and coating

forming a first layer consisting of an iron-nickel alloy of 10 to 50 (l O^) having a composition in the range of 01 to 1f on the first layer;
After complete tin plating in the range of /m', iron is treated with hot tin.
forming a second layer consisting of a tin-nickel alloy; and electrolytic chromate treatment on the second layer to convert it into ROM equivalent.
(a method for manufacturing a surface-treated αθ plate for electric resistance welding, comprising the step of forming a third layer consisting of metallic chromium and chromium water-conserving oxide in the range of 5 to 20 strokes/d) ,.Certainly, with this method, 1. The thin tint had both weldability and corrosion resistance of -rg1+, and it was possible to make C with some success, but as a result of subsequent investigation, the C contained in the can content was found to have sufficient corrosion resistance. It turns out that there are some things that aren't. Therefore, as a result of detailed investigation and re-examination ΔJ, the present inventors found that molten pot treatment is not necessarily necessary for forming the second layer in the prior art.
They also discovered that the structure of the chromate film makes a difference in its corrosion resistance, and completed the present invention by improving the technology of the prior application. In other words, the prior art uses chromium metal and chromium water-containing oxide to control the amount of water used, but although it is similar, it does not have sufficient corrosion resistance.
It was found that the amount of metallic chromium in the chromate film was small l/+. The metal layer in the chromate film D A
And the scattering of chromium hydroxide has changed dramatically! :? '
); investigated the relationship between cracking corrosion resistance and weldability, and found that the appropriate range and 14 paint corrosion resistance and bath weldability were both within the immediate range in Figure @1, and the metal chromium [11x was 2~/♂ on the embankment] In some cases, corrosion resistance is extremely low, but 2 W
/rr1, some had poor corrosion resistance. This is thought to be due to the increase in metallic chromium and the increased adhesion with the VC paint [7, especially at 2 mf/m or more, the effect of λ)1 is significant. From Figure 1, metallic chromium and chromium If the total amount of hydrated oxides (fx+y) is less than 5/d, the corrosion resistance will be poor; if it exceeds 2 (1"/11'), the weldability will be poor; if 5≦x+y≦20, the corrosion resistance will be poor; It can be seen that both the weldability is within the appropriate range of tl.From these results, in the present invention, the chromium equivalent of 1 of the metal chromium The range of ^y(η/rr?) is 2≦x,
It was limited to 5≦x −t−y≦2().

Subsequent training revealed that a sufficient effect can be recognized with an alloy layer as thick as the alloy layer. Therefore, in the present application, at the stage of forming the second layer, M+H- may be used with or without melting pot treatment.

In order to improve corrosion resistance after painting, it is better to consider the corrosion resistance after painting 1q, that is, after baking, and therefore, it is better to consider the corrosion resistance after painting 1q, that is, after baking. It is not necessarily necessary to carry out molten tin treatment (7L). Even if an alloy layer is formed during painting (2), the effect of improving the corrosion resistance of the alloy layer is sufficiently recognized.

The surface structure has a multi-layer structure consisting of a first layer made of a nickel alloy, a uniform, non-pole-free second layer made of an iron-tin-nickel alloy, and a third layer treated with a controlled amount of chromate, making it easy to weld and paint. This shows that both the corrosion resistance and the subsequent corrosion resistance are excellent.

A first layer consisting of iron and gold is formed on the steel plate, and tin plating is applied on top of it.Group 1. A second layer is formed by molten tin treatment using Bisha, and a third layer of chromate film is formed on the second layer by electrolytic chromate treatment (a multilayer surface structure is formed in step 7 [7, and the third layer is formed by electrolytic chromate treatment). Because we have strictly controlled the composition of the first layer and the adhesion of the second and third layers, its weldability and corrosion resistance after painting are extremely excellent, and the adhesion of the paint film is also excellent, making it a genuine product. The inventors were able to provide a surface-treated steel sheet for bath cans that satisfies all of the above-mentioned requirements for materials for welded cans.
