- the present invention relates to a piercing and rolling mill for seamless steel pipes, and more particularly, to a piercing and rolling mill that enables thin-wall piercing without deteriorating the workability of adjusting a position of a disc roll.
- the so-called Mannesmann pipe manufacturing method is widely used as a method for hot-working seamless steel pipes.
- a solid round billet heated to a high temperature is used as a material to be rolled, and the round billet is fed to a piercing mill (a so-called piercer) to pierce the center of the shaft.
- a piercing mill a so-called piercer
- the obtained hollow shell is expanded as it is or through an elonge mill having the same configuration as that of the above-described piercing mill, if necessary, to reduce the diameter and the thickness, and then the elongation rolling machine followed by a plug mill, a mandrel mill, etc. It is sent to K and rolled. After that, it passes through a stretch reducer, a reeler, a sizer, and the like, and then goes through a polishing process for shape correction and sizing to produce a seamless steel pipe as a product.
- the piercing rolling mill includes a pair of piercing rolls arranged above and below the pass line of the material to be rolled, and a pair of disc rolls arranged in a direction perpendicular to the arrangement direction of the piercing rolls.
- the material to be rolled is supported and swiveled by a scroll to perform piercing rolling ( and at least during rolling operation, these rolls and disc rolls are held together in the mill housing). The mutual positional relationship is firmly fixed.
- the rolled surface deteriorates as the rolling time elapses because the piercing roll is pressed against the material to be rolled maintained at a high temperature. .
- the disc rolls are worn by contact with the material to be rolled. Therefore, drill rolls and day scrolls must be replaced periodically.
- Japanese Patent Publication No. 63-64248 discloses a piercing mill in which rolls can be exchanged without using an overhead crane.
- the configuration of the machine is disclosed.
- the disc roll is supported by the cantilever from the drive shaft side, and there is a problem that sufficient rigidity cannot be obtained for the positioning of the portal during operation.
- the day scroll may oscillate at the material contact portion during piercing and rolling, which causes a problem that a flaw is generated on the surface of the material to be rolled.
- FIG. 1 is a diagram for explaining a state of a shape abnormality that occurs when a thin hollow shell is rolled by a piercing mill using a disk roll.
- the material to be rolled 1 is advancing while rotating in a direction perpendicular to the plane of the drawing by the piercing and rolling of the piercing roll 2, the plug 3, and the disc roll 4.
- the rolling reduction increases and the bulge of the outer peripheral length of the material to be rolled 1 increases, A part of the material to be rolled enters the gap between the disk edge on the rotation entry side of the material and the roll for punching, and guide flaws are generated on the outer surface of the material to be rolled.
- the edge of the disc roll 4 is parallel to the exit side of the perforating roll 2 and the gap between the rolls is reduced so that the gap is reduced.
- the skew (crossover) is made at a predetermined skew angle with respect to the pass line X—X serving as the rolling movement axis, and the disc roll 4 is arranged at an angle. In this case, if the support rigidity of the disc roll is insufficient, the disc roll deflects at the edge portion, and there is a problem that the generation of guide flaws is promoted. Disclosure of the invention
- the conventionally proposed piercing and rolling mill has a problem that the surface of the material to be rolled is apt to have flaws because the support rigidity of the disc roll is low.
