The invention provides an efficient cold rolling process for a special alloy precision strip. The efficient cold rolling process comprises the steps that the thickness h of a target strip is obtained; if the target strip thickness h is larger than or equal to s, a large tension output mode and a strong contact oil removal process control strategy are started; if the target strip thickness h is smaller than s, a micro-tension fluctuation mode and a weak contact oil removal process control strategy are started; and the rolling mill rolls the target strip to the specified product thickness, and rolling is finished. According to the strip thickness fed back by the thickness measuring system, a power source of the high-precision cascade power system and the input condition of an air cylinder of the self-adaptive flexible oil removal system are automatically executed, the rolling range of equipment is greatly widened, and both thick strips and thin strips are efficiently rolled. A process control strategy of large
