PURPOSE: A method of manufacturing a cold-rolled steel sheet is provided to manufacture a cold rolled steel sheet with excellent shape and surface quality by effectively inhibiting the side fault of a cold rolled coil like sticker fault when manufacturing the cold rolled steel sheet. CONSTITUTION: A method of manufacturing a cold-rolled steel sheet comprises next steps. The crown value of the hot rolled steel sheet is measured(102). The crown value measured is compared with a reference value for a crown value. When the crown value measured is below the reference, cold rolling accompanying BAF is performed on a hot rolled steel sheet(111). The BAF is performed on the cold rolled object to provide a cold rolled steel sheet(115). When the crown value measured is greater than the reference, the cold rolling accompanying CAL is performed on the hot rolled steel sheet. |
