The invention discloses a method for removing heat scratch defects from the surface of a cold-rolled sheet. The method includes hot rolling and cold rolling, wherein deviation of outer and inner ring steel plate temperature of a hot-rolled material volume and environment temperature is not greater than 5DEG C, roll temperature of cold rolls is less than 60DEG C, surface roughness of the first cold roll ranges from 1.0 micrometers to 1.2 micrometers, the surface roughness of the middle cold roll ranges from 0.45 micrometers to 0.65 micrometers, the surface roughness of the tail cold roll ranges from 4.0 micrometers to 4.5 micrometers, deflection of the first gate for cold rolling is less than 40%, the deflection of the other gates is less than 35%, rolling speed is less than 1000m/min, temperature of emulsified liquid is less than 60DEG C, concentration of the emulsified liquid ranges from 2.5% to 4%, and flux density of the emulsified liquid ranges from 3000L/min.m<2> to 5000L/min.m<2>.
