It is characterized in that aluminum killed steel satisfying the relationship 10-51 (weight % or more) is coiled at 550 to 720°C after hot rolling, pickled by a conventional method, and annealed after cold rolling.
この発明における各成分の限定理由について説明する。The reasons for limiting each component in this invention will be explained.

た。一方、Ｃ搦が０．１０係を越えると製品が硬質とな
ってプレス成形性が悪くなり、ホーロー用鋼板として軽
重しぐないので、その添加上限を０．１０％とした。(1) C C exists as a carbide in steel, but the carbide peels off from the matrix during cold rolling or voids are generated due to carbide destruction.
C has the function of improving nail resistance and astringency, but if its content is less than 0.02%, the above-mentioned effects are lost, so the lower limit of the amount of C added was set at 0.02%. On the other hand, if the C ratio exceeds 0.10, the product becomes hard and has poor press formability, and is not light or heavy as a steel plate for enamel, so the upper limit of its addition was set at 0.10%.
（２）１Ｍｎ

限定した。(2) 1Mn Mn requires about 10 times the amount of S to prevent hot embrittlement caused by S, but in terms of press formability and enamel firing strain, it is necessary to add as much Mn as possible. The smaller the amount, the better. Therefore, in consideration of these points, in the present invention, the amount of Mn added is limited to a range of 0.05 to 50%.

発明では、ＰとＳの含有量４ｏ、ｏｏａ〜０．０３０％
とした。(3) P and S P and S are impurity elements and cannot be avoided in certain amounts, but they affect the pickling speed in the enamel pretreatment, and their content is less than 0.005%. In this case, the pickling speed becomes slow and the workability of the enamel pretreatment becomes poor. On the other hand, if the amount of these substances is large, press formability deteriorates, so in this 5- invention, the content of P and S is 4o, ooa ~ 0.030%.
And so.

範囲を０．００１０〜０．０１００％とした。(4), N N is unavoidably contained in steel, and has the effect of making the steel hard and promoting age hardening, so it is better to have a smaller content. However, it is difficult to reduce the amount to less than 0.0010%, so in this invention, the addition range is set to 0.0010 to 0.0100%.

It is necessary to precipitate as N and make the product non-aging, and at least 0.005% or more is essential. On the other hand, if it is added multiple times, the manufacturing cost will increase, so in this invention it is set at 0.005 to 0.100%.

以、」二とした。(6), B B, like C, is an element necessary to improve the one-finger jump property. As shown in Figure 1, when the amount of C is 0.02% or more, B is It can be seen that the occurrence of nail skipping can be reduced by adding 0.0015% or more. On the other hand, adding a large amount of (3) not only increases the manufacturing cost but also makes the slab properties unstable.
．． 0050%. Furthermore, B is fixed in solid solution as BN in steel, but it is thought that the total amount of B does not become BH, but about half of that amount combines with N. Therefore, in the above composition range, solid solution N often remains in the steel, and the non-aging property, which is one of the characteristics of aluminum killed cold rolled steel sheets, is lost. As a result of various considerations, S oJ

It has been found that non-aging properties can be achieved by satisfying x, 0-51. It's good (N%-0,511-・B%)
is less than 0.0005%, that is, the amount of solid solute N is 0.00
If it is less than 0.05%, the steel plate is practically non-aging, so
The aforementioned restrictions are not necessary. Therefore, (N%-05・

０〜０．０５０％とした。7-(7) Cu cuIi is an element that affects the porcelain adhesion and the pickling speed in the porcelain pretreatment. In this case, the pickling speed becomes slow and the workability of the enamel pretreatment becomes poor. Therefore, in this invention, the addition range of O is set to 0.01
The content was set at 0 to 0.050%.

えると熱延鋼板の脱スケールが困難になるためである。In this invention, steel containing two consecutive components is hot-rolled by normal means and then rolled at 550 to 720°C.
This is because carbide precipitates finely at temperatures below 550°C.
This is because the single-claw jump rate decreases, and on the other hand, if the temperature exceeds 720°C, it becomes difficult to descale the hot rolled steel sheet.

脱炭焼鈍を行う必要がある。The recrystallization annealing method may be a normal box annealing method or a continuous annealing method, but in the case of continuous annealing, solid solution C is used in the line.
It is preferable to perform a precipitation treatment. Aluminum guild cold-rolled steel sheets manufactured by this method are manufactured using 2
Although it is suitable for steel plates for porcelain enamel, in order to prevent carbon boiling, O, jii' should be 0.01% or less for steel plates for enamel porcelain, in which the upper glaze is directly attached to the steel plate. It is necessary to perform decarburization annealing to achieve this.
次に、この発明の実施例について説明する。Next, embodiments of the invention will be described.

After hot rolling at a winding temperature of 560 °C, pickling
It was cold rolled to am thickness. After that, annealing (box annealing, continuous annealing, decarburization annealing) was performed, and finally 1st stage temper rolling was performed. Table 2 shows the results of the mechanical properties and enamel properties of the aluminum-killed steel sheets produced in this manner.

The adhesion of the lower f111 agent was measured using a DEI adhesion tester when a Borrow steel plate was pickled with SO for 2 minutes. Furthermore, in the case of continuously annealed material, the hot rolling coiling temperature was 680°C.

できない。As is clear from Table 2, Comparative Steel E has a C content equal to that of Invention Example 1, and has poor nail-skipping resistance, with a large number of nail-skippings occurring. Unfortunately, comparative steel E has a small amount of C, so even if solid solution C is precipitated by continuous annealing, solid solution C does not precipitate sufficiently.
(ndex) A/I is high and it is not time-limited. Comparative steel F61 has a low B content that is outside the range of the present invention, and therefore has poor four-claw jumpability, making it unsuitable as a steel plate for enamel. Comparative steel G has Cu amount and 5oJAe%X
(N%-〇, 5・Dan-B%) 1 is outside the scope of the present invention, and the porous adhesion and aging resistance are poor. Furthermore, Comparative Steel H is an aluminum guild cold-rolled steel sheet without the addition of B, and has poor single-claw jumpability and porous adhesion, and cannot be used as a steel sheet for enamel.

Although it is 7Ky/-, this value is practical-L non-aging property, and there is no problem at all with respect to aging property.
