In recent years, the production of soft materials by continuous annealing has been studied in place of the box annealing method, which is extremely inferior in productivity and has poor material uniformity in the longitudinal and width directions of the coil.
When manufactured by the conventional continuous annealing method using ordinary low carbon steel, a large amount of solute C remains in the steel due to rapid cooling after annealing, which causes strain aging during baking coating and subsequent processing such as can making. Sometimes molding defects such as fluting and stretcher strain occur.

In the method described in Japanese Patent Laid-Open No. 263143, the cost is high because extremely low C steel is used. In addition, JP-A-60-6
In the method described in Japanese Patent No. 7627, low carbon steel is used, but since it is hot rolled after hot rolling, the form of carbide and the precipitation state of AlN become non-uniform in the coil longitudinal direction and width direction, and as a result The uniformity of the material in the longitudinal and width directions of the final product is poor. Furthermore, since high-temperature heating above the A 1 transformation point is performed in continuous annealing, a steel plate having a thin plate thickness such as a can material is likely to cause a threading problem such as a heat buckle.

C is an element that plays an important role in the material and strain aging during baking coating. Therefore, the amount of the constituent elements other than C and the manufacturing conditions are kept constant within the range of the present invention, samples having different amounts of C are prepared, and the samples are subjected to heat treatment corresponding to baking coating, and then subjected to a tensile test. The yield point elongation was measured and the relationship between the C content and the yield point elongation was investigated. The results are shown in Fig. 1. C amount is 0.050 to 0.0
Within the range of 85% by weight, the yield point elongation after baking coating can be suppressed within 5%, and the problem of defective molding such as fluting can be avoided as described above. Therefore, the C content is limited to the range of 0.050 to 0.085% by weight. More preferably, if the C content is controlled within the range of 0.060 to 0.080% by weight, the yield point elongation after baking coating can be suppressed within 4%, which is more advantageous for molding defects such as fluting. .

If Mn is less than 0.05% by weight, the problem of hot embrittlement occurs, so it is necessary to increase it. In addition, 0.
If it is contained in an amount of more than 60% by weight, it becomes hard and it becomes impossible to produce a soft material having T3 or less by the method of the present invention.
Therefore, the amount of Mn is limited to the range of 0.05 to 0.60% by weight.

Al and N are also important constituents of the present invention. If N is not precipitated as AlN during hot rolling, fine AlN precipitates during continuous annealing and inhibits the growth of crystal grains, and as a result, the structure becomes fine grains and hardens.
On the other hand, when high-temperature winding is performed to accelerate the precipitation of AlN, the uniformity of the material such as hardness in the longitudinal direction and the width direction of the coil deteriorates as described above. So low-temperature winding with AlN
The conditions for precipitating were investigated by changing the atomic ratio of Al and N. The results are shown in Figure 2. In Fig. 2, the horizontal axis is Al / N
(Atomic ratio), and the vertical axis represents a value obtained by dividing the amount of N existing as AlN by the total amount of N. Winding temperature is 680 ℃
In the high temperature winding of Al, even if the ratio of Al / N is small, most of N is precipitated as AlN, but in the low temperature winding of 550 ° C., most of N is precipitated as AlN and Al / N ≧ 15. Need to Further, an increase in the amount of Al leads to high cost and hardening, so the upper limit is made 0.10% by weight. At this time, the amount of N satisfying the atomic ratio Al / N ≧ 15 is 0.0036% by weight or less.

When the coiling temperature after hot rolling is set to 620 ° C. or higher, as described above, due to the difference in cooling rate after coiling, the form of carbide or AlN in the longitudinal direction or the width direction of the coil is obtained.
Does not become uniform, resulting in poor uniformity of the material after annealing. On the other hand, if the temperature is lower than 550 ° C, it becomes difficult to control the winding temperature and the shape. Therefore, the winding temperature after hot rolling is limited to the range of 550 ° C or higher and lower than 620 ° C.

When the overaging treatment temperature is lower than 350 ° C., it takes too long to precipitate the solid solution C. On the other hand, when the temperature exceeds 450 ° C, the amount of equilibrium solid solution C at that temperature increases, and the amount of solid solution C of the final product after cooling also increases. Therefore, the overaging temperature is limited to the range of 350 ° C to 450 ° C. The overaging time is limited to 30 seconds or more in order to sufficiently precipitate the solid solution C.
