The invention relates to a technological lubrication system setting method for a cold rolling single stand reversing mill. Through adjusting the flow of an emulsified liquid during a rolling process,the rolling pressure in the whole rolling process can be uniform, the whole rolling force deviation is smaller, the thickness fluctuation during the whole rolling process is reduced, and the problemsthat during an actual production process of an existing cold rolling single stand, the relatively fixed emulsified liquid flow is adopted, so that a big difference of the rolling force of each pass iscaused, and the thickness difference control fluctuation during the production process is larger are solved.
