The invention relates to the field of metallurgical production and can be used for casting hollow billets of steel, cast iron, non-ferrous metals.,

The goal is to expand the technological capabilities of the device by casting ingots with a non-circular cross-section.

in fig. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one.

The device contains a water-cooled mold 1 and a mandrel 2, between which a hollow billet 3 is formed. There is a platform 4 on which a drive 5 of radial movement of the casting tank 6 is installed, which is equipped with contact rollers 7, the Dorn is brought to the bracket 8. when moving it along the rails 9 on the wheels 10 with the help of the drive 11 and the coupling 12.

The device works as follows.

The mold 1 and the mandrel 2 are elliptical in shape and jointly reciprocate. Liquid metal is fed into the gap between them and an ingot 3 is formed here. The casting bowls (two) are mounted for rotation on the platform 4 around the axis of the ingot 0.

However, in addition, the rotational movement of the container is installed with the possibility of radial movement, for example, with a drive in the form of a pneumatic cylinder through the sleeve 12, which press the casting container 6 with the roller 7 to the top

of the mandrel 2. Thus, when the container is rotated on the platform 4 due to the contact of the roller 7 with the mandrel 2 and rolling it along the mandrel, the supply location of the liquid metal with any shape of the mandrel 2 and ingot 3 changes. In this example, two bowls with angles of rotation when rotating up to ± 90 ° along rails 9 on wheels 10. This movement provides a drive 11.

The mandrel is suspended from the bracket 8, and the crystallizer-mandrel assembly can be performed not--, movable during the periodic movement of the ingot 3.

The number of sectors from which the casting capacity is made depends on the section of the cast ingot.

The use of the invention will allow casting round billets and elliptical section blanks.
