Zusammenfassung:rolled stock production, possibly hot rolling of sheets and strips. SUBSTANCE: method comprises steps of supplying water-air mixture to portion of roll barrel near outlet of deformation zone; creating water-air mixture by spraying water stream with use of compressed air with pressure of 1-4 MPa at setting specific water flowrate in range 10-90 cu.m/sq.m x h. Method allows to receive homogeneous aerosol with fineness degree and sprinkling density that enhance thermal conditions for rolling roll operation. EFFECT: enhanced quality of rolled strips, increased rate of rolling process, reduced degree of air contamination with dust-like scale. 1 tbl, 1 ex
