| titleOfInvention | Cold rolled steel sheet manufacturing method |
| abstract | A method for producing a high-tensile cold-rolled steel sheet having excellent ductility and stretch flangeability is provided. A method for producing a cold-rolled steel sheet comprising a metallographic structure in which a main phase is ferrite and a second phase includes a low-temperature transformation generation phase, which includes the following steps (A) to (C): (A) By mass%, C: more than 0.010% and less than 0.10%, Si: more than 0.10% and 2.0% or less, Mn: 1.50 to 3.50%, P: 0.10% or less, S: 0.010% or less, sol.Al: 0.10% And a slab having a chemical composition containing N: 0.010% or less is subjected to hot rolling to complete rolling in a temperature range of 3 or more points to form a hot-rolled steel sheet, and the hot-rolled steel sheet is completed for the rolling. After 0.4 seconds, the steel sheet is cooled to a temperature range of 720 ° C or lower and wound in a temperature range of 400 ° C or higher; (B) a cold rolling step of cold rolling the cold rolled steel sheet to the hot rolled steel sheet; and (C) An annealing process in which the cold-rolled steel sheet is subjected to soaking in a temperature range of (Ac 3 point-40 ° C) or higher.
