Abstract

PURPOSE:To decrease the number of rolls and to provide simple construction by setting the number of backup rolls that support intermediate rolls at 1:1 and supporting the respective rolls by means of bearing chocks. CONSTITUTION:Work rolls 2a, 2b are of a small diameter and have virtually no elastic deflections because chocks 5a, 5b for backup rolls have high rigidity and shafts 13a, 13b have short spans, thus the work rolls are capable of high rolling-down rolling. Since the rolls 2a, 2b of a small diameter are supported from diagonally behind by means of respectively two pieces of intermediate rolls 3a, 3b, they have virtually no deflections against the forces in a horizontal direction owing to the tension of a plate material to be rolled. Since the respective rolls are supported by the chocks, respectively and have large movable extents in a vertical directions, the rate of adjusting the gap between the rolls 2a and 2b is large, the range of rollable thicknesses is wide and the changing of the rolls is easy.

In order to reduce energy consumption in the field of IFE, from the viewpoint of energy saving in ceramic clay, instead of the conventionally used and long I-dem type four-pronged, heavy-voltage electric machine, a 1-〇m! Since the thickness of the plate can be significantly reduced by rolling, a high pressure reduction process II* is required for 4Ii.

Although it has been used for a long time, the current demand from the industry is that it is suitable for a wide range of medium-thin OSS and even thin sheets. In addition, the number of reinforcing rows #1/4S and #1/4b is large, the structure is complex, and the cost of the rolling mill is high.
