| 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, P: 0.10% or less, S: 0.010% or less, sol.Al : Slabs with a chemical composition of 2.00% or less and N: 0.010% or less are subjected to hot rolling that completes rolling in a temperature range of Ar 3 or higher with a rolling reduction of more than 15% in the final 1 pass. After cooling to a temperature range of 780 ° C or lower within 0.4 seconds, winding in a temperature range of more than 400 ° C, cold rolling the resulting hot-rolled steel sheet, and then (Ac 3 point -40 ° C) or higher temperature Soak at 50 ° C or higher at a cooling rate of less than 10.0 ° C / s, then cool to a temperature range of 500 ° C or lower and 300 ° C or higher, and perform annealing for 30 seconds or longer in this temperature range. A cold-rolled steel sheet having a metal structure in which the main phase includes a low-temperature transformation generation phase and the second phase includes retained austenite and polygonal ferrite is produced.
