Abstract In light of the enormous force fluctuation during the rolling acceleration and deceleration in the double cold reduction mill. After fully considered the equipment and technological characteristics of the emulsion direct application system，the effect of rolling velocity and emulsion concentration on the plateout oil film thickness，deformation zone oil film thickness，friction coefficient，forward slip，rolling force was analyzed. On this basis，the relationship between the emulsion lubrication and the rolling velocity was established. Subsequently，an online control technology of the emulsion concentration in double cold reduction mill was developed by adjusting the emulsion concentration in real time during the rolling acceleration and deceleration in the double cold reduction mill. Then，this technology was applied in a 1 220 double cold reduction mill，reduced the force and thickness fluctuation effectively and improved the rolling stability and product quality，which has further popularization and application value.
