| Synopsis : In plate rolling, slab is rolled not only in longitudinal but also in transverse directions so as to get required dimensions of plate. Plate rolled in this way, however, develops unequal plastic deformation, making crop losses increased in top and bottom portions of both sides. The authors have developed a new method to measure the plastic deformation behavior during rolling by the composite picture method and formulated equation to estimate plate plan view pattern. A new plate rolling method called MAS rolling has been established, making it possible to prevent the unequal plastic deformation and manufacture almost rectangular plan view pattern plates. By MAS rolling, total product yield of plate has been improved by 4.4% to a new world record of 93.8% in Jan. 1979 at No.2 Plate Mill of Mizushima Works, Kawasaki Steel Corporation. |
