Abstract With reference to the problems of fixed emulsion flow distribution，being unble to be adjusted dynamically with the change of rolling speed，this study made a lot of field experiments and theoretical research to study the comprehensive optimization setting technology of emulsion in cold rolling process. The technology fully considered the mechanical and technological characteristics of cold rolling unit，and put forward a dynamic setting method of emulsion flow. The best overall cooling effect of cold rolling unit and uniform cooling capacity among stands were taken as the control targets，the maximum permissible emulsion flow and optimum emulsion flow in theory were taken as constraints，then the cooling capacity coefficient of emulsion was present for the first time. The method was developed to use in a sertain 1 220 five stands cold rolling unit，and obtained good results. The emulsion cooling capacity of each stand was fully utilized，the abnormal increase of the rolling force and rolling pressure upside down caused by inadequate emulsion flow were avoided，creating greater economic benefits for enterprises with further popularization and application values.
