Silicon steel cold continuous rolling lubricating system and method

The invention discloses a silicon steel cold continuous rolling lubricating system and method. The technical problem that an existing lubricating system cannot meet lubricating production of multi-mark silicon steel cold continuous rolling is solved. The lubricating system comprises the rack, the low-concentration emulsion circulating unit, the medium-concentration emulsion circulating unit and the high-concentration emulsion spraying unit, and emulsion with different concentrations can be selected to be sprayed to the selected rack or/and strip steel, so that when different products are rolled, the high-concentration emulsion can be sprayed to the rack or/and the strip steel. The corresponding lubricating system can be adaptively selected for rolling lubrication, and one or two or three of the low-concentration emulsion circulating unit, the medium-concentration emulsion circulating unit and the high-concentration emulsion spraying unit can be used for spraying combination; therefore, the lubricating system
