Abstract

FIELD: metallurgy, in particular, gaging and rolling of rails in intermediate passes. SUBSTANCE: four-high set has passes of upper and lower lines. Open and closed grooves of upper and lower passes not cooperating with first middle pass are displaced one relative to the other during boring due to tapering of open flange of base for value equal to stop cone wear of upper and lower rolls during operation of set with middle roll. EFFECT: increased efficiency, improved shape of profile and enhanced reliability in operation.
