THREE ROLLERS SCREW ROLLING MILL AND ITS BASIC EQUIPMENT MILL Russian patent published in 1994 - IPC

FIELD: metal rolling. SUBSTANCE: rollers of three rollers screw rolling mill are set at low angle of rolling ( 10 -30 deg. ) and with significant tangential shift ( 0.3 - 0.75 of medium diameter of the rollers). There are additional design solutions for similar scheme of the rolling mill, that allow to increase significantly accuracy of the pass setting due to relieving adjusting mechanisms of rolling pressure and increases sensitivity of the mechanisms. EFFECT: basic equipment of the screw rolling mill increases rolling pass setting accuracy and sensitivity of its adjusting mechanism. 4 cl, 8 dwg
