Abstract: Enviromentally-friendly silicon steel rolling emulsion with high lubricating property was developed using enviromentally friendly base oil and additives. The lubricating performance was analyzed by MRS-10A four-ball tester and 4-high cold-rolling mil and compared with the KD traditional emulsion. The results show that relative to the traditional KD emulsion, the developed cold-rolling emulsion shows a higher lubricating performance, a better annealing cleanliness, and that the minimum rolling thickness is decreased by 13.3%. After rolling, silicon steel strip shape and surface quality is more ideal. It is concluded that the developed enviromental emulsion can meet the need of the high speed silicon steel cold- rolling process .
