FIELD: manufacturing processes for producing cold rolled thin steel sheets.
SUBSTANCE: method comprises steps of supplying lubricating liquid containing predetermined amount of palm oil to intervals between predetermined stands of continuous rolling mill. According to invention lubricating liquid is fed onto rolled strip before first stand of mill and, if necessary between second and third stands of mill. Palm oil is used multiply in reverse cycle of lubricating liquid having oiliness 0.3 - 0.4% at flow rate of palm oil in range 4 - 7 g/m2 of rolled strip.
EFFECT: lowered production costs due to reduced consumption of palm oil without degrading product quality.
