ことになる。The original boards to be painted come in various widths, thicknesses, and materials. Regarding board width: 711mm, 760mm, 914m
+n, 1000mm, 11100m, 1230wn, etc. are coated, but depending on the difference in plate IIJ, the axial deflection of the surface of the 7J skin pass roll as shown in Figure 1 differs. For board j early, 016th printing~a,
The glaze speed is applied between 0 mm and 0 mm, but since the skin pass deviation differs depending on the board thickness, if the board thickness changes, the deflection of the skin pass roll surface in the axial direction will increase. The steel type of Itatoga is 5AD1008-8AEI (
150, which is cold-rolled or zinc-plated, but the skin pass load varies depending on the quality of the plate, and the axial deflection of the skin pass roll table [HL differs].The skin pass of Cit et al. The axial deflection of the roll surface, that is, the deformation of the axial surface shape of the roll body, is solved by using the hydraulic skin pass roll 14', and a uniform rolling edge is applied to the painted steel plate. That is, in FIG. 7, 71': Hydraulic pressure is generated in the hydraulic chamber 25 of the front hydraulic skin pass roll 14',
The surface shape of the roll body surface 140 in the axial direction is bent as shown by the solid line into a state shown by the dotted line. As a result, the coated steel plate is rolled down uniformly in the tj and +lJ directions.
