Further, the peripheral speed of the rolling roller and the linear speed of lateral movement are the same speed or increased by 5%. Next, the rolling material feeding side peripheral walls of the pair of rolling rollers are inclined with respect to the axis and have a gripping angle of the material, and the rolling material feeding side peripheral walls are parallel to each other by inclining the rolling roller peripheral walls.

せたものである。Further, in the apparatus of the present invention, a pair of rolling roller bearing-supporting sliders are opposed to each other in the vertical direction of the rolling material in the direction perpendicular to the direction of travel of the rolling material. Then, the rolling roller is pushed by the slider with the gripping angle of the material being held, the slider is connected with reciprocating means, and the rolling roller is connected with rotating means associated with the reciprocating movement. It is a slab rolling apparatus characterized by that. In addition, the reciprocating means,
A hydraulic cylinder and a piston rod fitted into the hydraulic cylinder. Next, the rotating means is a rack fixed to the frame, a pinion that meshes with the rack, a coaxial gear of the pinion, and an interlocking gear of the rolling roll shaft that meshes with the coaxial gear. Further, the pair of rolling rollers has an equal diameter at least 1/2 of the roller length on the feed side of the rolled material, and is inclined so that the outer peripheral walls of the remaining rollers face each other substantially in parallel.

A plurality of pinions are desirable. In short, any structure can be adopted as long as it can accurately and surely perform reciprocating motion for rolling. Since the upper rolling roller in the above is lowered by its own weight when there is no rolled material, it is desirable to appropriately lift it by a suspension spring or hydraulic action. Further, it is desirable to move on a roller during reciprocal rolling, and a known cooling means is appropriately adopted during hot rolling.

で、厳密な平行性を要求しない。As described above, in the present invention, a roller having an equal diameter is used over a considerable width (at least 1/2 or more) in order to equalize the peripheral speeds of the rolling rollers on the material feeding side, and the remainder is a cone. By inclining each other, the walls of the opposing rollers are made substantially parallel to each other. Although the peripheral wall of the cone-shaped portion does not become exactly parallel by adjusting the rolling gap, it does not require strict parallelism as long as it can achieve the purpose of leveling rolling.

Needless to say, a conventionally known roller gap adjusting device can be applied, for example, the frame is composed of two upper and lower parts, the upper frame holding the upper rolling roller is moved up and down by a screw, and the screw is driven by power.
