Section for continuous-casting of continuous casting installations

The utility model relates to the field of metallurgy, and more particularly to continuous casting plants.

Known roller wiring machines for alternating continuous casting of wide or narrow ingots, containing drive and idle rollers mounted in the bearings of the frames of the roller sections (AS No. 1375405, class. 22 D 11/128).

The closest analogue is the roller section of the secondary cooling zone of the continuous casting installation, containing the upper and lower rollers installed in the end and intermediate supports, fixed in the frames of the upper and lower cassettes by fixing nodes of rigid connection in the form of anchor rods passing through the end supports (A.С No. 1477511, class B 22 D 11/128).

When using the above analogues, the following disadvantages are found: with the need to increase the width of the cross sections of two casting slabs simultaneously, the load from the ferrostatic pressure and the dressing forces on the rollers increase, and the loads on the intermediate bearings increase more than on the end supports, which leads to uncontrolled elastic deflections of the roller frames sections. As a result, the solution of the rollers in the region of the inner faces of the slabs cast simultaneously increases more than the extreme faces, which entails additional deformations and stresses at the interface between the solid and liquid phases of the slab, worsening its quality. Also, these analogues of metal.

The technical task of the proposed utility model is to eliminate unacceptable deflections of the frames of the roller sections, maintain a stable solution of the rollers, improve the quality of the cast slabs, ensure reliability in operation, reduce the metal consumption of the equipment.

steel casting, including upper and lower rollers installed in the end and intermediate supports, fixed in the frames of the upper and lower cassettes by fastening fastening nodes passing through the end supports, according to the utility model, the intermediate supports mounted in brackets mated through measuring spacers are connected with frames of the upper and lower cassettes fastening nodes rigid connection.

In this case, the fastening nodes of the rigid connection can be made in the form of anchor rods with wedge locks,

The drawings show: in FIG. 1 shows a section of a double-sided roller wiring installation for continuous casting of steel, side view; in Fig.2 a section aa in Fig. 1.

The double-strand roller wiring section of the continuous steel casting installation consists of upper 1 and lower 2 cassettes, in which the upper 5 and lower 6 rollers are mounted in the end 3 and intermediate 4 bearings, while the intermediate bearing supports 4 are mounted in the brackets 7, interfaced through 8 dimensional spacers determining the technological solution of the roller wiring for casting slabs 9. The frames 10 and 11 of the upper 1 and lower 2 cassettes are combined into a section of the roller wiring by fastening nodes of a rigid connection in the form of rods 12 with wedge locks 13, p ohodyaschimi through the end bearing supports 3 and bracket 7 supports four intermediate rollers 5, 6. The rollers 6 are connected with a drive 14.

The device operates as follows.

The casting of two slabs 9, including different along the width, is performed simultaneously. In the process of passing through the roller wiring, the slabs 9 squeeze the upper 5 and lower 6 rollers from a predetermined position, but due to the presence in the intermediate supports 4 of fastening nodes of a rigid connection in the form of anchor rods 12 with wedge locks 13, the specified roller setting is not violated.

quality of molded slabs

metal consumption decreases. reliability in work is provided,
