FIELD: process engineering.
SUBSTANCE: invention aims at lubricant saving at strip rolling. Claimed method comprises application of lubricant in metal rolling, particularly, in rolling of strip (28) fed between two rolls (2', 2''). Lubricant concentration in roll space is increased owing to preparation of the mix of lubricant and carrier gas in sprayer (4). Said mix is forced to separate spraying jets (5) to produce common continuous jet (19) to be sprayed over rolled strip width. Said jet consists of flat lubricant jets (9) each being formed by spraying jet (5). The latter has tip (18) provided with at least two outlets (10). Sprayed jet (19 is applied on surface (21) of at least one of working rolls and/or surface (23) of rolled strip (28). Proposed device incorporates the appropriate equipment.
EFFECT: perfected method.
