FIELD: metal working.
SUBSTANCE: invention relates to a rolling mill stand. The rolling mill stand has an upper working roll and a lower working roll. An upper cooling apparatus is located at the output side of the rolling mill stand, used to cool the upper working roll. The upper cooling apparatus has an upper spraying pipe with upper spraying nozzles and a lower spraying pipe with lower spraying nozzles. The lower spraying pipe is located between the rolled product and the upper spraying pipe. Some of the upper spraying nozzles are made in the form of flat-jet nozzles. Some of the lower spraying nozzles are made in the form of full-jet nozzles.
EFFECT: highly effective and uniform cooling of the upper working roll is ensured as a result.
