By making the inter-center distance P of 3 and 15 short, rolling was performed by the oval hole type of the first rolling mill 12 without providing a holding guide for the material 20 to be rolled between both rolling mills 12 and 14. The material 20 can be accurately guided and supplied to the round hole die of the second rolling mill 14. That is, the adjustment work and the inspection work of the holding guide due to the order change can be omitted, and the generation of defective products due to the holding guide can be eliminated. Further, the length of the entire intermediate row can be shortened by the amount of the holding guides eliminated. It should be noted that it is possible to set an arbitrary interval between the rolling roll having the round hole shape and the rolling roll having the oval hole shape, that is, between the rolling devices 10 and 10 without providing a holding guide. Therefore, in the embodiment, as shown in FIG. 1, between the second rolling mill 10 and the third rolling mill 10 from the upstream side in the intermediate row, and between the third rolling mill 10 and the fourth rolling mill 10. Cooling means 40 are provided between the respective cooling means. This cooling means 40
Functions to cool the material 20 to be rolled, which has been heated by each rolling device 10 to increase its temperature, and to maintain the temperature of the material 20 at a temperature suitable for rolling by the rolling device 10. In the example, two sizing mills 42 having three rolling mills are arranged along the pass line PL of the material 20 to be rolled to form a finishing row.

When rolling the material 20 to be rolled having a large diameter, the adjusting gear 38 is rotated in the required direction by the driving means, and both adjusting shafts 38, 38 are rotated in the same direction. As shown in FIG. 4, the worms 34, 34 disposed on each adjusting shaft 32 are eccentric members 2 fitted on the upper or lower rolling shaft 28.
Since the tooth portions 26b and 26b of the gears 6 and 26 are meshed with each other, the eccentric members 26 and 26 are attached to the stand 2 as the adjustment shaft 32 rotates.
The inside of the through hole 24a of 4 is rotated in a required direction. Since the twisting directions of the worms 34, 34 arranged on the adjusting shafts 32, 32 are set as described above, the upper eccentric member 2
6, 26 and the lower eccentric members 26, 26 rotate in mutually opposite directions, and as shown in FIG. 11, the axis C 1 of the rolling shafts 28, 28 supported by the respective eccentric members 26, 26, The distance of C 1 changes. As a result, as shown in FIG.
The gaps between the rolling rolls 13 and 13 which are fitted onto the outer surfaces 8 and 28 and face each other are widened. And the gap between the rolling rolls 13, 13 is
When the value set according to the size of the material 20 to be rolled is reached, the rotation of the adjusting gear 38 is stopped to complete the gap adjustment. Therefore, the material to be rolled 2 whose order is changed
