| titleOfInvention | Manufacturing method of high r-value cold rolled steel sheet with small in-plane anisotropy |
| abstract | (57) [Summary] [Purpose] High r with small in-plane anisotropy showing excellent workability. Establish a means to stably manufacture cold-rolled steel sheets on an industrial scale. [Constitution] C ≦ 0.05%, Si ≦ 0.3%, Mn: 0.01 to 0.4 %, S ≦ 0.02%, sol.Al: 0.01 to 0.08%, N ≦ 0.01%, Alternatively, a specific amount of B may be further included, or in addition to this, a specific amount of one or more of Ti, Nb, Zr and V may be added to the formula [C equivalent]-[Ti Equivalents / 4] ≤ 0.0020, including at least hot steel slabs, a) rolling in the final pass at a temperature of 1200 to 900 ° C, reduction ratio of 3 Perform primary rolling of 0% or more, b) Next, 1200 ℃ ~ 900 Precipitation treatment is carried out by holding in the temperature range of ℃ for 1 to 60 minutes, c) Rolling with a total reduction of 30% or more in a temperature range below the Ar 3 point, d) Rapid heating again to the γ region to cause α → γ reverse transformation, e) Cooling in the γ region and a total reduction ratio: 50 ~ 97% cold rolling, f) recrystallization annealing at 550 ~ 900 ℃, Processing and heat treatment are sequentially performed in the process including the following processes. |
