| titleOfInvention | Cold rolled steel sheet manufacturing method |
| abstract | [PROBLEMS] To produce a high-tensile cold-rolled steel sheet having excellent ductility, work hardenability and stretch flangeability. SOLUTION: In mass%, C: more than 0.020% and less than 0.30%, Si: more than 0.10% and 3.00% or less, Mn: more than 1.00% and 3.50% or less, and in some cases, an appropriate amount of Ti, Nb, V, Contains one or more of Cr, Mo, B, Ca, Mg, REM and Bi, P: 0.10% or less, S: 0.010% or less, sol.Al: 2.00% or less, and N: 0.010% or less The average grain size of grains having a chemical composition and having a bcc or bct structure surrounded by grain boundaries with an orientation difference of 15 ° or more is 6.0 μm or less, and the average number density of iron carbides present in the metal structure After cold rolling a hot-rolled steel sheet having a thickness of 1.0 × 10 -1 piece / m 2 or more, and subjecting the resulting cold-rolled steel sheet to a soaking treatment in a temperature range of (Ac 3 point-40 ° C) or higher Then, it is cooled to a temperature range of 500 ° C. or lower and 300 ° C. or higher, and is annealed by holding in that temperature range for 30 seconds or longer.
