造方法に関する。The present invention relates to a method for producing a high-strength ultra-thin steel sheet for cans having a small in-plane anisotropy, and more particularly, to a so-called ear suitable for drawing. The present invention relates to a method for producing a high-strength ultra-thin steel sheet with little occurrence (earring).

ルミ、鋼基材共に増加傾向にある。Tin cans and TFS cans are made of three-piece cans consisting of a lid, a torso, and a bottom, and DI (drawn and ironed) cans and DRDs, which are formed by squeezing the torso and bottom and squeezing.
There are two-piece cans such as (draw / redraw) cans and DTR (draw / thin / redraw) cans. Since the two-piece can has an excellent can function in terms of leak resistance and the like as it has few joints, both aluminum and steel base materials tend to increase.

分に解決されているとは云い難い。"Problems to be solved by the invention" From the viewpoint of weight reduction, resource saving and cost reduction, it is required to reduce the gauge of a two-piece can. However, when the gauge is reduced, the strength during can production and during transport decreases. There is a tendency for even deformation due to a decrease in pressure resistance after filling the contents. Attempts have been made to make cans using DR with high temper quality in order to solve the strength and pressure reduction. However, in DR, ears are generally generated due to the anisotropy of the substrate during drawing, and the yield and the quality are inevitably reduced. The cause of the occurrence of these ears depends on the can-making process, but is mainly due to the anisotropy of the steel sheet. At present, it is difficult to say that the problem of the anisotropy of the hard thin steel sheet has been sufficiently solved. .

≦ R 2 ≦ 0.75R 1 +98 An ultra-hard ultra-thin cold-rolled steel sheet manufacturing method with improved anisotropy has been proposed (JP-A-59-113123).
However, as a result of the additional test, surface defects due to residual scale in pickling and insufficient strength of the steel sheet were recognized, and the problems of the prior art were not always sufficiently solved. In the DI can molding method, a plate-shaped material (blank) is punched from a sheet or a coil-shaped cold-rolled steel sheet, squeezed into a cup-shaped molded body (1st cup), and then squeezed two or three times to form a 1st cup side wall. It is made by reducing the thickness of the material.

が、DI缶成形法のようにカップ側壁缶素材の積極的な厚

り加工のみである点で異なる。In addition, the DRD can molding method has a common point with the DI can molding method in that it is a can made by drawing blanks, but aggressive thickness reduction of the cup side wall can material like the DI can molding method The difference is that the secondary processing is only the drawing processing without performing the squeezing processing which is the processing.

る。Furthermore, the DTR can forming method is similar to the DRD can forming method in that the blank is formed by drawing, but the deep drawing blank is given a high wrinkle holding force to reduce the side wall of the can.
It differs from the above two can making methods in that the overhanging process is performed.

プの縁高さが不揃いとなり、所謂「耳」が発生する。こ
の耳は、成形缶を成形ポンチから抜き取る時に抜け不良

くの不要部分である。In the manufacture of the DI, DRD, and DTR cans, if the material has high anisotropy and the flow of the material by plastic working is not uniform, the edge height of the cup is not uniform, and a so-called “ear” is generated. These ears are not only unnecessary parts that are caused not only when pulling out the molding can from the molding punch but also when removing the molding can, and are completely unnecessary parts that need to be removed after molding.
本発明は、上記３種の２ピース缶の中でも特にDRD、D
TR缶用素材として優れた鋼板を提供するものである。The present invention is particularly applicable to DRD and D among the above three types of two-piece cans.
It provides excellent steel sheet as a material for TR cans.

高い耐力を保持した調質度が要求される。That is, in the DRD can or DTR can molding, since the thickness of the material is not reduced by squeezing in the can making process, it is necessary to use a steel plate having a thickness smaller than that of the DI can element material. Also, since DRD cans and DTR cans have been developed with the aim of reducing the thickness of the product plate, the quality of the material is required to be high with high yield strength.

や、缶表面の印刷歪の発生という不都合を招来する。こ
のため異方性の小さい素材が強く望まれていた。Also, since DRD cans and DTR cans are not squeezed in the processing process, various surface-treated steel sheets (pre-coated steel sheets) pre-printed and coated in sheet or coil form, or steel sheets laminated with a pre-printed plastic film (Laminated steel sheet) can be used. However, when DRD cans or DTR cans are formed using such pre-coated steel sheets or laminated steel sheets, if the anisotropy is large, the plastic flow of the material is not uniform, so that ears and wrinkles are generated, and printing distortion on the can surface is caused. This leads to the disadvantage of occurrence. Therefore, a material having small anisotropy has been strongly desired.

とする缶用極薄鋼板の製造方法によって構成される。The present invention provides a high-strength electrode in which a continuously cast steel slab is hot-rolled at a finishing temperature of at least three points of Ar, then wound at a temperature of 700 ° C or less, pickled, primary rolled, continuously annealed, and secondary rolled in this order. In the production of thin steel sheets, continuous slabs, C: 0.006-0.02

And from unavoidable impurities, the primary reduction ratio R 1 of 80% to 90%
, And the and configured by the production method of the extra-thin steel sheet for a can, characterized in that the secondary rolling reduction R 2 is 20% to 45%.

Ｃ量は缶強度上必要とされる引張強度および、耳高さか
ら決定され、本発明においては0.006〜0.02％とする。"Action" Regarding steel composition C is one of the important elements of the present invention. In Figure 1, considering to secure the secondary rolling reduction R 2, C is the tensile strength in proportion to the amount of C to 0.01% increases rapidly. Also,
If it exceeds 0.01%, the tensile strength does not increase despite the increase in the amount of C. However, if C exceeds 0.02%, the ear height increases at a high primary rolling reduction of 80 to 90%, which is not desirable. That is, FIG. 2 shows the ear ratio (ΔH / H × 100) when the can A was drawn. FIG. 2 shows that the ear ratio is good.
It can be seen that the amount is in a certain range. Therefore, the C content in the present invention is determined from the tensile strength and ear height required for the strength of the can, and is set to 0.006 to 0.02% in the present invention.
Siは、缶用材料としては耐食性に有害な元素である
が、Alキルド鋼としては、不可避的に含有される元素で
あり、上限は0.06％である。Si is an element harmful to corrosion resistance as a material for cans, but is an unavoidable element contained in Al-killed steel, with an upper limit of 0.06%.
Mnは、不純物であるＳによる熱延時の赤熱脆性を防止
する為に、必要な元素であり、上限は0.6％である。Mn is an element necessary for preventing red hot brittleness at the time of hot rolling due to S as an impurity, and has an upper limit of 0.6%.
Ｐは、材質を硬化させる為高強度という観点からは有
用であるが、偏析し、缶材としては、耐食性で有害の
為、上限は0.03％である。P is useful from the viewpoint of high strength because it hardens the material, but segregates and is harmful to the corrosion resistance of the can material, so the upper limit is 0.03%.
Ｓは、熱延時の赤熱脆性を生じさせる有害元素であ
り、極力少ない方が望ましいが不可避的に混入する成分
であり、上限は0.03％である。S is a harmful element that causes red-hot embrittlement during hot rolling, and is preferably a component as small as possible, but is an unavoidable component, and the upper limit is 0.03%.
Alは、製鋼後脱酸剤として投入される成分でAlNとし
て析出し、Ｎの固溶強固作用を低減させるので、少ない
程望ましいが、その上限は0.08％であるのが望ましい。Al is a component added as a deoxidizing agent after steelmaking and precipitates as AlN, and reduces the solid-solution and strong action of N. Therefore, the smaller the amount, the better, but the upper limit is desirably 0.08%.
Ｎは、Ｃ、Mn、Ｐと同様に強化作用を有し、本発明の
主要因のひとつであり、下限を0.0018％とした。Ｎは多
い程望ましいが多過ぎると一次圧延後の焼鈍のｒ値を小
さくし、また、製鋼時添加するフェロ窒化物の歩留まり
を考慮し、上限は0.015％である。N has a strengthening effect similarly to C, Mn, and P, and is one of the main factors of the present invention, and the lower limit is made 0.0018%. The N content is preferably as large as possible, but if it is too large, the upper limit is 0.015% in consideration of the r value of annealing after primary rolling and the yield of ferro-nitride added during steelmaking.
製造条件について、 熱間圧延について、加熱炉抽出温度としては、低すぎ
ると、熱延時の温度確保が難しく、又、冷延板の高強度
化に寄与する固溶Ｎ分を考慮すると高い程望ましいが、
経済性を考慮すると、下限を1100℃、上限を1200℃とす
るのが望ましい。熱延仕上げ温度は、板厚精度制御及び
イヤリングを考慮し、Ar3以上とする必要がある。Regarding the production conditions, for the hot rolling, if the heating furnace extraction temperature is too low, it is difficult to ensure the temperature during hot rolling, and it is preferable that the higher the solid solution N content that contributes to increasing the strength of the cold-rolled sheet, But,
In consideration of economy, it is desirable to set the lower limit to 1100 ° C and the upper limit to 1200 ° C. The hot rolling finishing temperature needs to be Ar 3 or more in consideration of thickness accuracy control and earring.
酸洗後の１回目の圧延率は、90％を超えるとイヤリン
グが大きくなるため上限を90％、下限は熱延板の製造の
安定性を考え80％とすると良い。If the first rolling ratio after pickling exceeds 90%, the earring becomes large, so the upper limit is 90%, and the lower limit is preferably 80% in consideration of the production stability of the hot-rolled sheet.
再結晶焼鈍は、箱型焼鈍を施すと、所定の強度を得る
為の二次圧延率が高くなるため、イヤリングに望ましく
なく、又、経済的でもない為、さらに箱型焼鈍は、焼鈍
後の結晶粒が大きくなる為、絞り加工後のフランジ加工
時にフランジ割れが発生しやすく、又、結晶粒が大きい
と加工による肌荒れも大きく、耐食性にも有害であるた
め連続焼鈍に限定した。Recrystallization annealing, when subjected to box-shaped annealing, because the secondary rolling rate to obtain a predetermined strength is increased, it is not desirable for earrings, and also because it is not economical, further box-shaped annealing, after annealing Since the crystal grains are large, flange cracks are likely to occur at the time of flange processing after drawing, and if the crystal grains are large, the surface roughness due to the processing is large and the corrosion resistance is harmful.
第２回目の圧延は、圧延率が低過ぎると所定の強度が
出ない。その下限は20％であり、又、圧延率が高過ぎる
とイヤリングに対して望ましくなくその上限は50％であ
る。In the second rolling, a predetermined strength is not obtained when the rolling ratio is too low. The lower limit is 20%, and if the rolling reduction is too high, it is undesirable for earrings, and the upper limit is 50%.

After recrystallization annealing, the relationship between the secondary rolling ratio and strength was investigated. For C content of 0.006 to 0.06%, DR after annealing
There is no difference in strength after rolling, and 0.006
