STEP-BY-STEP ROLLING MILL FOR FLAT LONG BILLETS Russian patent published in 2017 - IPC B21B1/42 

FIELD: metal processing.

SUBSTANCE: mill relates to metal forming and can be used for rolling of long flat billets of bands and strips, preferably, of difficult-to-deform steels and alloys. Mill includes device for consecutive indexing of flat long workpiece and rolls arranged in mill with smooth body, one of which is installed with possibility of back-and-forth movement and reversing rotation for deformation of a flat blank straight stroke and reverse run after stepwise movement of billet. Possibility to increase degree of reduction is ensured by that top roll axis is located in vertical plane, that is perpendicular to vertical plane, where longitudinal axis of lower roller, upper roller is equipped with reversing drive and is installed with possibility of back-and-forth movement along lower roller for deformation of flat billet in transverse direction by forward stroke and reverse run after stepwise movement of billet.

EFFECT: rolling of long flat billets of bands and strips, primarily, of difficult-to-deform steels and alloys.
