FIELD: machine building.
SUBSTANCE: invention relates to the rolling. Continuous small-section mill with a roll dividing gauge system of comprises a roughing mill group consisting of 1–9 stands, two intermediate groups of stands, and finishing rolling blocks. Stands 1–3 are made with box gauges 12, 13 and 14. Stands 4 and 5 are made with twin flange gauges 15 and 16. Stands 6 and 7 comprise twin oval gauges 17 and 18. Stand 8 comprises oval gauges 19 and 20. Stand 9 is made with round gauges 21. Gauges 19 and 20 are deployed relative to the axis of a-a rolling at an angle of 23÷25°.
EFFECT: device provides the simplified mill setup and increased accuracy of geometric dimensions of the resultant profiles by 2,3 %.
