Large strain-introducing working method and caliber rolling device |
摘要 |
A method of rolling a material in two more continuous passes is disclosed. The method includes rolling the material with a flattened-shaped caliber in a first pass, and subsequently rolling with a square-shaped caliber in a second pass. The rolling is performed with a first pass caliber having a flattened shape, wherein the ratio of the length (2A01) of minor axis of the first pass caliber to an initial width (2A0) is (A01/A0)<=0.75; and a second pass caliber, wherein the ratio of a diagonal dimension (2AS1) of the second pass caliber to the length (2B1) of the major axis of the material after the first pass is (AS1/B1)<=0.75 to introduce the large strain into the material.
