20130017118 | ASYMMETRIC ROLLING DEVICE, ASYMMETRIC ROLLING METHOD AND ROLLED MATERIAL MANUFACTURED USING SAMEAANM Jeong; Hyo-TaeAACI GangneungAACO KRAAGP Jeong; Hyo-Tae Gangneung KRAANM Choe; Byung-HakAACI GangneungAACO KRAAGP Choe; Byung-Hak Gangneung KR - An asymmetric rolling method for rolling a rolling material by using at least one pair of working rolls comprises rolls rotating at the same linear velocity and having different diameters. An asymmetric rolling apparatus may comprise a first roll contacting a first surface of a rolling material, a second roll having a diameter different from that of the first roll and contacting a second surface of the rolling material opposite to the first surface, and a power providing unit for providing power to each of the first and second rolls to adjust a ratio between angular velocities of the first and second rolls. | 01-17-2013 |
