PLATE ROLLING METHOD Russian patent published in 2012 - IPC B21B1/38 

FIELD: metallurgy.

SUBSTANCE: invention is aimed at the increase of mechanic and functional properties of sheets rolled at the plate reversing mill containing rough and finishing rolling mills. The method includes multiple pressing of plate metal block on the width forming ledges on its surfaces by a couple of rolls of rough mill with girded ledges and further multiple pressing in the finishing with smooth rolls. Formation of fine structure of phase elements is ensured due to the fact that the girded ledges are made on the half of rough mill roll bodies. At this between the rolling in the rough mill the block is turned in its surface through 180° and from ledges of 3-20 mm height at the surface of the block. Girding ledges of rolls in couple are located at the opposite sides and can have spiral form.

EFFECT: increased mechanic and functional properties of sheets rolled at plate reversing mills.
