Description of the Related Art Recently, a DI drawing method shown in FIG. 5 has been used as a method for producing a cylindrical battery can having a closed surface on one end, which is mainly on the plus side, and an opening on the other end, which is attached on the minus side. Being developed. In this DI drawing method, when the base material M is punched out from the sheet steel plate S, it is punched while being drawn into a shallow cylindrical shape having a bottom wall M-1 and a peripheral wall M-2, and the cup is subjected to the next one step. Deep drawing is performed to form a cylindrical shape having a required depth and diameter.

図ることができる。When the above-mentioned DI drawing is used, since only the peripheral wall is stretched in the deep drawing process of the cup, as an example, the thickness of the bottom wall is 0.4 mm and the thickness of the peripheral wall is reduced to 0.15 mm. The ironing rate (reduction rate) with respect to the plate thickness can be more than double the conventional value. As described above, when the peripheral wall is thin, the volume of the hollow portion is increased, the amount of the filler is increased, and the battery characteristics can be improved. Further, since the processing steps are only a total of two steps including a cupping step of punching a cup from a sheet steel sheet which is a can forming material and a DI step of drawing,
It is possible to significantly reduce the number of processing steps and accordingly reduce the manufacturing cost.

It was a low carbon steel of 0.05% by weight and was manufactured by the method shown in FIG.

れてロールマークが付いてしまう。However, the batch annealing (step # 1) has the following disadvantages. First, in batch annealing, as shown in FIG. 7, since steel plates S ′ wound in a hoop shape are annealed in a state of being stacked inside an annealing furnace W, the occurrence of scratches due to the adhesion of the steel plates S ′ to each other. In order to prevent this, it is necessary to apply sodium silicate to the surface of each steel plate S ′ to form a film. However, when the film of this sodium silicate breaks, the broken film becomes powder and iron powder is generated, which causes deterioration of the quality of the steel sheet surface.
In particular, when iron powder adheres to the surface of the rolling roll during temper rolling (process # 2), the adhered iron powder is transferred to the steel plate and a roll mark is attached.

It is heated in the range of 550 to 600 ° C. for 1 hour, kept at this temperature for 2 to 10 hours, and further cooled to 100 ° C. in 23 to 33 hours.
It takes as long as 6 hours, which increases costs.

鈍開始から炉出まで約５分程度の時間しかかからない。On the other hand, in the continuous annealing performed in the above step # 4, since the sheet steel sheet is annealed while being fed by a roll, it is not necessary to apply sodium silicate to form a film,
The temperature distribution is also good. Further, in the case of continuous annealing, as shown in FIG. 9, it is rapidly heated to 600 to 900 ° C. in 1 minute and kept at this temperature for 30 seconds, cooled to 400 ° C. in 20 seconds and passed for 2 minutes and 30 seconds. An aging treatment is performed, and the material is rapidly cooled to 100 ° C. in 15 seconds. Therefore, in the case of continuous annealing, it takes about 5 minutes from the start of annealing to leaving the furnace.

For 5 wt% low carbon steel, continuous annealing cannot be performed in place of the batch annealing in the above step # 1 for the following reason.

ましくない。That is, the above-mentioned low-carbon steel has an α solid solution of iron (ferrite) and FeC 3 (perlite) at room temperature.
In the case of the unannealed material, the cementite (carbon atom A) in the ferrite tends to concentrate in the portion where the disposition of the iron atoms B is different (dislocation portion D), as shown in FIG. is there. When an external force is applied to the steel sheet, the dislocation portion D moves along the slip surface X, causing deformation. However, if cementite is concentrated in the dislocation portion D,
The resistance generated by cementite is added to the movement resistance of the dislocation portion D, and the yield point extension Yl shown in FIG. 11A is generated.
Then, for the steel plate having the yield point extension Yl, the above D
When the I drawing process is performed, a line pattern (Luders line) is generated on the surface of the battery can 1 shown in FIG. In particular, since the top portion 1a comes into contact with the eyes when the battery is completed as a finished product, the presence of the above Luders line is not preferable in terms of the appearance of the battery.

バッチ焼鈍を行わざるを得なかった。On the other hand, when the above low carbon steel is heated, cementite becomes a supersaturated solid solution and re-employment occurs. Therefore, when annealing and temper rolling are performed, the yield point spread Yl disappears as shown in FIG. 11 (B). . However, in the case of continuous annealing, since rapid heating and rapid cooling are performed as described above, strain is not completely removed by recrystallization, and as time elapses, as shown in FIG.
As shown in (C), a phenomenon (aging) in which the yield point spread Yl occurs again occurs. On the other hand, in the case of batch annealing,
Because of slow heating and slow cooling, strain-free crystals are generated and the above aging does not occur. Therefore, conventionally, continuous annealing cannot be performed in the step of annealing the cold-rolled steel sheet in order to prevent the generation of the Luders line due to aging,
There was no choice but to carry out batch annealing.

Thus, the annealing process can be performed by continuous annealing, and the purpose is to shorten the manufacturing time, reduce the cost, and the like.

As for the temperature setting in this continuous annealing, first, as shown in FIG. 9, first, the temperature is rapidly heated to 730 ° C. for 1 minute and held for 30 seconds, and then rapidly cooled to 400 ° C. for 20 seconds. Further, overaging treatment is performed at 400 ° C. for 2 minutes and 30 seconds, cooled to 100 ° C. in 15 seconds, and then removed from the furnace. The time required for continuous annealing is about 5 minutes, and the annealing process is completed in an extremely short time. Due to the continuous annealing, the metal structure of the steel sheet 3 is recrystallized to be in a strain-free state. In the case of this continuous annealing, the temperature distribution of the steel sheet is uniform because the annealing treatment is performed while the steel sheet is fed by the rolls as described above, and it is not necessary to provide a coating on the steel sheet. The temperature setting for continuous annealing is not limited to this, and the maximum temperature may be set to 600 to 900 ° C.

First, in batch annealing, as shown in FIG. 7, since the steel sheets S ′ wound in a coil shape are annealed in a state of being stacked inside the annealing furnace W, the occurrence of flaws due to the adhesion of the steel sheets S ′ to each other. In order to prevent this, it is necessary to apply sodium silicate to the surface of each steel plate S ′ to form a film. However, when the film of this sodium silicate breaks, the broken film becomes powder and iron powder is generated, which causes deterioration of the quality of the steel sheet surface.
In particular, when iron powder adheres to the surface of the rolling roll during temper rolling (process # 2), the adhered iron powder is transferred to the steel plate and a roll mark is attached.

ましくない。That is, the above-mentioned low carbon steel is composed of iron α solid solution (ferrite) and Fe 3 C (perlite) at room temperature.
In the case of the unannealed material, the cementite (carbon atom A) in the ferrite tends to concentrate in the portion where the disposition of the iron atoms B is different (dislocation portion D), as shown in FIG. is there. When an external force is applied to the steel sheet, the dislocation portion D moves along the slip surface X, causing deformation. However, if cementite is concentrated in the dislocation portion D,
The resistance generated by cementite is added to the movement resistance of the dislocation portion D, and the yield point extension Yl shown in FIG. 11A is generated.
Then, for the steel plate having the yield point extension Yl, the above D
When the I drawing process is performed, a line pattern (Luders line) is generated on the surface of the battery can 1 shown in FIG. In particular, since the top portion 1a comes into contact with the eyes when the battery is completed as a finished product, the presence of the above Luders line is not preferable in terms of the appearance of the battery.

However, in the case of continuous annealing, since rapid heating and rapid cooling are performed as described above, strain is not completely removed by recrystallization, and as time elapses, as shown in FIG.
As shown in (C), a phenomenon (aging) in which the yield point spread Yl occurs again occurs. On the other hand, in the case of batch annealing,
Because of slow heating and slow cooling, strain-free crystals are generated and the above aging does not occur. Therefore, conventionally, continuous annealing cannot be performed in the step of annealing the cold-rolled steel sheet in order to prevent the generation of the Luders line due to aging,
There was no choice but to carry out batch annealing.

Performs temper rolling in%. The relationship between the stress and strain of the steel sheet at the time of finishing the temper rolling is as shown in FIG. 11 (B) described above, and the yield point elongation disappears. In addition, in this example, the steel sheet 3 had a carbon content of 0.002 to 0.003.
Since the ultra-low carbon steel sheet of weight% is used, aging does not occur, the stress-strain relationship is maintained in the state shown in FIG. 11B, and the yield point stretch does not occur again. This has a carbon content of 0.00, as shown in FIG.
This is because if it is less than 9% by weight, cementite does not exist at room temperature and carbon atoms are present in the α solid solution of iron, and the present inventors have found that the above carbon content is an ultra low carbon steel of less than 0.009% by weight.
