(The gap between 5f and the work roll (2) (2)', that is, the gap between the surface of the work roll (21 (21') and the surface of the partition part (6), is set to a predetermined value, (6
) (6)' to urge the work rolls (2) (2<) in the separating direction. After supplying pressure liquid from the pressure supply source to each hydraulic reservoir chamber (1) to generate static pressure on the upper and lower work rolls (21 (2+ and beam < 5) < 5f), the gap adjustment device (71 (7f) Cancel the settings.

The force in the vertical direction and the force in the rolling direction working on f are transmitted through the beam (5) (55)...
The upper and lower work rolls (21 (2)
1 in particular, since not only the shaft end but also the body is supported in the vertical direction, the bending of the work roll (21 (2S) by the rolling blade is suppressed. Therefore, even in a two-high rolling mill without a backing roll, accuracy can be improved. Good rolling is possible.

ｔばその断面形状は同図（ロ）の様になる。Figure 9 (a) shows the case where the pressure distribution is made uniform, and the cross-sectional shape of the rolled material is flat as shown in (b), and Figure 10 (
If the center is made thicker as shown in (a), the cross-sectional shape becomes a concave lens ((b) in the same figure), and if the center is made smaller as shown in Figure 11 (a), the cross-sectional shape becomes a convex lens ((b) in the same figure). , and the pressure distribution as shown in Figure 12 (a))
The cross-sectional shape of the t-bar is as shown in the same figure (b).

ばよい。When the pressure in each hydraulic reservoir αD is independently opened, a pressure difference occurs between adjacent hydraulic reservoirs αDO]. The most obvious example is when one side is at pressure P and the other side is at atmospheric pressure; in this case, the pressurized liquid passes through the partition θo and enters the adjacent liquid pressure reservoir (
1]), and when it passes through the partition (2), the pressure of the pressure liquid drops from P to atmospheric pressure. The pressure gradient in this partition increases as the pressure difference between the liquid pressure reservoirs αυα1) increases.
When the pressure gradient is large, the leakage l of the pressure fluid also becomes large. Therefore, in order to reduce the amount of pressure fluid leakage, as shown in Figure 15, a plurality of grooves 04) are carved in the partition part 04), and the partition part (c) is given a labyrinth packing function to reduce the pressure gradient. Just do it.

させることも勿論可能である。In the above embodiment, the work rolls of the two-high rolling mill were supported using static pressure bearings, but the backing rolls of the four-high rolling mill may be supported in the same way. Furthermore, since the roll is not restrained in the axial direction due to the support relationship between the beam and the roll, it is of course possible to move the roll 7 feet in the axial direction.

１してやれは圧延機の形状制御をすることもできる。As described above, in the present invention, since the beam itself acts as a static pressure bearing, the structure that requires a conventional bearing block is simplified, and a hydraulic reservoir corresponding to a bearing block is integrally machined into the beam. Dimension control is easy and accuracy is immediately improved. Furthermore, by independently controlling the pressure in the hydraulic reservoir chamber, the shape of the rolling mill can also be controlled.
