得ることができない。FIG. 5 shows a part of a cross section of a conventional drum (one cross section including a rotating shaft) and a cross section of a nozzle 4.
Shown in In the figure, the engraving 21 on the drum surface forms the transverse bone 9 of the lattice shown in FIG. The molten metal flowing from the molten metal introduction section 12 is supplied to the lattice engraving section via the gate 11. The molten metal that fills the engraved portion is worn away at the contact surface of the nozzle with the drum with the rotation of the drum 1 for constant volume. FIG. 6A shows a partially enlarged cross section of the drum and the nozzle in this state. The abrasion is performed by the sliding portion 80, but the contact surface between the nozzle and the drum is in a pressurized state so that the molten metal does not enter the sliding portion 80. Therefore, one of the contact surfaces is worn, but the material is usually selected so that the nozzle side is worn. The problem here is that the nozzle wears out locally. In other words, the mold for forming the lattice body as shown in FIG.
And the engraving of the transverse bone 9... Are on the same circumference with a circular cross section perpendicular to the drum rotation axis, and have the non-sliding portion 81 in which the sliding portion does not exist even when the drum rotates. With the abrasion of the sliding portion 80 of the nozzle, the convex portions 12... Are formed as shown in FIG. Therefore, in the state shown in FIG. 3B, it is no longer possible to obtain a lattice body having a desired size.

As the means, for example, a mold having a sculpture for forming a lattice body having a shape as shown in FIG. 1 is used. That is, the engraved portions along the rotation direction of the drum are arranged so as to be discontinuous on the same rotation circumference of the drum. FIG. 8A shows a partially enlarged cross section of the molten metal scraping portion of the drum and the nozzle in this case. As shown in the drawing, the non-sliding portion shown in the prior art exists as a sliding portion 80 ', and as a result, the wear of the nozzle at the contact surface with the drum becomes uniform.

4 mm, thickness 1.6 mm, draft angle of engraving 30 degrees, 10 pieces are engraved on the drum circumference. The material of the drum is SUS304, and the material of the nozzle is FC250. On the other hand, a conventional drum for forming a lattice as shown in FIG. 4 was prepared under the same conditions and compared. Cumulative operating time 1
00 hours later, when the thicknesses of the horizontal members 9 of the lattice body and the frame horizontal members 91 were measured, in the case of using the conventional drum,
While the thickness of the lattice changed from 1.6 mm at the beginning to 1.3 mm, the thickness of the lattice using the drum of the present invention did not change. The gist of the present invention is to achieve the object if the engraved portion along the rotation direction of the drum is discontinuous on the same rotation circumference of the drum, so that the shape of the lattice body is not limited to this embodiment. No, for example, FIG.
