る。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) This invention is a DWI used for filling beer and carbonated drinks.
Can (Drawing & Wall Ironing
This invention relates to a two-piece steel plate for cans, which is the original plate for tin cans.
〔従来の技術］
最近、ＤＷＩ缶用ふりきは、缶コスト低減を目的に板厚
を薄く、材質は硬く、そして錫目付を低減させる傾向が
進んでいる。[Prior Art] Recently, there has been a trend toward thinner plate thicknesses, harder materials, and lower tin weights for the purpose of reducing the cost of cans for DWI cans.
ただし、板厚を薄くすると缶強度が低下するので、材質
の固い原板を使って缶強度を維持していた。However, reducing the thickness of the can reduces the strength of the can, so hard original plates were used to maintain the strength of the can.
しかし、缶強度を維持するために硬質材を使うと、製缶
加工性が悪（なって、生産性が悪化した。However, when hard materials were used to maintain the strength of the can, the processability of the can was poor (and productivity deteriorated).
さらに錫目付を少なくした場合、錫はＤＷＩ加工に際し
て固体潤滑剤としての作用も有しているので、やはり製
缶の生産性を悪化させることになる。Furthermore, if the tin weight is reduced, tin also acts as a solid lubricant during DWI processing, so the productivity of can manufacturing will be deteriorated.

必要な缶強度の得られる２ピース缶用調板（ふりき）が
求められていた。That is, in the past, under such a situation, reduction of plate thickness, maintenance of can strength with thin plate thickness, and reduction of tin weight could not achieve the intended results. Therefore, it has excellent workability during DWI processing, and the finished can is hard.
There was a need for a two-piece can trimming board that would provide the necessary can strength.

ことを目的としている。This invention was made in view of the above-mentioned conventional problems, and the following thoughts and experiments were conducted in the process of developing the invention. That is, the material of the plastic is mostly determined by the crystal grain size and solid solution components (C, N). If the grain size is made smaller, the steel sheet becomes harder, but there is a limit to how much the grain size can be made smaller because cold rolling properties and temper rolling properties deteriorate in the manufacturing process. But hard? The eight components do not reduce rollability except in a certain range and become hard through heat treatment, so in the can manufacturing process, the cleaning process, painting, and printing after DWI processing harden the can, so the required can We obtained knowledge that reached strength. Based on this, we set the composition of the steel plate for two-piece cans, and especially set the amount of solid solute N (Ntotal-NasAI2N) to 0.00.
The purpose is to solve the above problem by setting the content to 2 to 0.010%.

本発明において、Ｃ量は少なすぎても多すぎても仕上が
ったふりきは第１図に示すように硬くなる領域（イ）、
（ロ）と、その間に軟質材の得られる領域（ハ）がある

って材質のバラツキも大きくなる不安定領域である。な
お、Ｃ量を少なくすれば結晶粒径が大きくなるので圧延
性は改善される。In the present invention, even if the amount of C is too small or too large, the finished furiki will become hard as shown in FIG. 1 (A).
There is a region (b) between which a soft material can be obtained (c). When the amount of C is 0.02% or less, a large amount of solid solute C remains, and the furiki becomes hard (region (a)). However, this region (a) is an unstable region in which the amount of solid solute C varies greatly, and therefore the material quality also varies widely. Note that if the amount of C is reduced, the crystal grain size becomes larger, so that rolling properties are improved.
一方、Ｃ量が０．０８％を超えると（領域（ロ））、結
晶粒径もそれに相関して細かくなり、その結果、鋼板が
硬くなって現存する冷間圧延機、調質圧延機で圧延する
に際し、圧延性は極端に悪くなる。On the other hand, when the C content exceeds 0.08% (region (B)), the grain size also becomes finer, and as a result, the steel sheet becomes harder and cannot be used in existing cold rolling mills and temper rolling mills. During rolling, the rolling properties become extremely poor.
Ｃ量が０．０２〜０．０８％の範囲内の領域（ハ）でぶ
りきが軟質になるのは、固溶Ｃ量が少なく、結晶粒径も
大きい領域のためであって、この固溶Ｃ量が少なくなる
のは、セメンタイトが細かく均一に分散しているので、
焼鈍の冷却工程で固溶Ｃが効率よく析出するためである
。またＣ量が０．０２〜０．０８％の範囲であれば製缶
後の材質のバラツキも安定することがわかった。これは
Ｃ量をこの領域で規制したものは固溶Ｃ量も安定して少
なくなるためと考えられた。従ってＣ量は０．０２〜０
．０８％が適量である。The reason why tin becomes soft in the range (c) where the amount of C is within the range of 0.02 to 0.08% is because the amount of dissolved C is small and the crystal grain size is large. The amount of molten C decreases because cementite is finely and uniformly dispersed.
This is because solid solution C is efficiently precipitated in the cooling step of annealing. It was also found that when the C content is in the range of 0.02 to 0.08%, variations in material quality after can manufacturing are stabilized. This is thought to be because when the amount of C is regulated in this range, the amount of solid solute C is stably reduced. Therefore, the amount of C is 0.02~0
．． 0.8% is an appropriate amount.
Ｓｉはふりきや、Ｃｒ、Ｎｉ、ＡＮ等のめっきを施して
表面処理銅板に仕上げる際、めっき密着性を悪くして耐
食性にも悪影響を及ぼすために０゜０２％以下とした。When finishing a surface-treated copper plate by dusting or plating with Cr, Ni, AN, etc., Si impairs plating adhesion and has a negative effect on corrosion resistance, so the content was set to 0.02% or less.
Ｍｎはその含有量を０．０５から０．３０％の範囲に限
定した理由は、Ｍｎ量が０．０５％より少ないと硬さが
不充分となり、また０、３０％を超えると圧延性が悪く
なる。また、熱間圧延の際に現れる青熱脆性を防く意味
からも０．０５％以上が必要となる。The reason why the Mn content is limited to a range of 0.05 to 0.30% is that if the Mn content is less than 0.05%, the hardness will be insufficient, and if it exceeds 0.30%, the rollability will deteriorate. Deteriorate. Further, 0.05% or more is required to prevent blue brittleness that appears during hot rolling.
Ｐ、Ｓはそれぞれ、ふりきの延性を減少し、脆化や耐食
性の劣化をもたらす元素なので、０．０２５％を上限と
した。Since P and S are elements that reduce the ductility of the steel sheet, causing embrittlement and deterioration of corrosion resistance, the upper limit was set at 0.025%.
次に、本発明においてはＮ成分を０．００３〜０．０１
５％の範囲に限定する点を重要な構成要件の一つとする

られる。Next, in the present invention, the N component is 0.003 to 0.01
One of the important constituent requirements is to limit the amount to a range of 5%. That is, the present invention improves rolling and DW by adjusting the amount of solid solution nitrogen that does not adversely affect rolling properties.
The purpose is to obtain cans that are soft until subjected to I processing, but after DWI processing, become hard due to heating when the paint is baked on the can, and means to make this purpose possible. can be obtained by adjusting A1 and the amount of N.

た。Figure 2 shows the amount of solid solute N in the steel sheet (Ntotal-NasA
fN) and the hardness of tinplate (HR30T) in each process. In the conventional example, the amount of solid solute N was small, so
Furiki is soft and the degree of hardening is small even after aging or DWI processing, so there was little room to reduce the plate thickness in order to maintain the required can strength. However, when the amount of solid solute N is 0.02% or more, the baking of the coating and printing of DI cans will be affected by aging treatment as shown in the graph (approximately 210"C x 20 minutes). Graph of hardness of wood■
The degree of age hardening is large when the hardness is expressed as , and therefore the plate thickness can be made sufficiently thin in proportion to this hardness.

工法が改良できれば上限を設ける必要はなくなる。In this way, the degree of hardening increases as the amount of solid solution N increases, but on the other hand, if the shape after neck-in processing in the DWI processing step exceeds the boundary line X in Fig. 2 to the right in the figure, Becomes unstable. Therefore, in the present invention, the upper limit of the amount of solid solute N is set to 0.010%. Graph ■ is D
The hardness of the furiki after WI processing is shown. Note that if the neck-in processing method can be improved, there will be no need to set an upper limit.

ない。従ってＡｆｆｉ：０．０２％〜０．０６％、 Ｎ
： ０．００３〜０．０１５％が適切である。FIG. 3 shows the relationship between the amount of N, the amount of Affi, and the amount of solid solution N. As can be seen from the figure, if /l is small and the amount of N is large, a large amount of solid solution N remains. However, if the amount of A2 is small, Al2O3 is difficult to form clusters in the molten steel, so its flotation separation is not promoted, and many nonmetallic inclusions such as Al2O3 remain in the steel, resulting in the part (F) in Figure 4. As shown in , this is not preferable because it causes flange cracking during DWI processing. Therefore Affi: 0.02%~0.06%, N
: 0.003 to 0.015% is appropriate.
〔実施例］
以下、本発明による実施例を第１表の数値によって示す
。これは表に示した条件で作成した１６種類のぷりきを
用いて、ＤＷＩ加工法による実製缶試験を実施したもの
である。[Examples] Examples according to the present invention will be shown below using the numerical values in Table 1. This is an actual can test conducted using the DWI processing method using 16 types of plastic molds prepared under the conditions shown in the table.
ＤＷＩ加工性評価は、製缶後、塗装印刷前に缶外壁面を
目視観察して、傷付き状況で評価した。The DWI processability evaluation was performed by visually observing the outer wall surface of the can after can manufacturing and before painting and printing, and evaluating the degree of scratches.
傷付きが大きいと製缶加工中及び製品毎での耐錆性が悪
く、好ましくない。また傷付きが大きいことは、ダイス
も傷めていることになり、ダイス寿命が短くなることは
明らかである。If the scratches are large, the rust resistance during the can manufacturing process and for each product will be poor, which is not preferable. Moreover, if the scratches are large, the die is also damaged, and it is clear that the life of the die will be shortened.

Cans with pressure resistance above this level are required, and cans with lower strength will be severely deformed even when filled with something subject to internal pressure, such as carbonated beverages, and their commercial value will be significantly impaired. In addition, flange cracking was evaluated based on the crack occurrence rate after processing the flange.

。Here, it is not always possible to detect 100% of cracks in the actual can manufacturing process, and the comparison steel (symbol 1 in the table), which is a conventional example with a high incidence of cracks,
If the furiki made in steps 3 to 3 and 13 to 16) are used, there is a high possibility that broken cans will reach the consumer, which is not only undesirable in terms of food hygiene, but also poses a risk of causing social problems.
