Abstract: An emulsion flow optimization method suitable for a cold continuous rolling mill that aims to achieve vibration suppression. The method aims to suppress vibrations by an oil film thickness model and a friction coefficient model. An optimum set value of the emulsion flow rate for each rolling stand that aims to achieve vibration suppression is optimized on the basis of an over-lubrication film thickness critical value and an under-lubrication film thickness critical value that are proposed. The method greatly reduces the incidence of rolling mill vibration defects, improves production efficiency and product quality, treats rolling mill vibration defects, and improves the surface quality and rolling process stability of a finished strip of a cold continuous rolling mill.
