Description

The utility model relates to metallurgy, in particular, to multi-strand continuous casting machines for blooms and high-quality billets.

A device for continuous casting of steel according to the application of Germany No. 10062440 (publ. 06/20/2002), containing a supporting frame with a mold and a reciprocating mechanism, and located under the mold guide section of the roller wiring of the stream. To improve protection, the mold, together with the swinging frame and the reciprocating drive acting on it, is placed in a housing closed from above and from the side.

In the known device for continuous casting there is no electromagnetic stirring system, which has proven itself to minimize axial segregation of the workpiece.

The bloom continuous casting machine free from this drawback is described in the article “Reconstruction of the bloom caster No. 2 at OEMK in Russia” on the SMS Demag Aktiengesellschaft website http://www.sms-demag.com., P.2-7. The bloom blank continuous casting machine contains a mold, a resonant rocking mechanism of the mold with a spring guide, equipped with a swing table and an electromechanical drive mounted on the rocking mechanism support frame, an electromagnetic stirring inductor located at the outlet of the mold, and also a guide section of the roller wiring of the stream. This bloom continuous casting machine is the closest to the offer.

The transfer of force from the electromechanical drive to the oscillating table of the mold leads to a violation of the trajectory and stability

oscillation of the mold, especially with small amounts of mold travel, due to gaps in the drive.

The proposed utility model solves the problem of more accurately moving the mold along a given trajectory and improving the quality of the cast ingot by stabilizing the trajectory of the mold of continuous casting machines for bloom and high-quality billets.

To achieve the specified technical result in a continuous casting machine containing a mold, the swing mechanism of the mold with longitudinal and transverse springs, compensating springs, equipped with a swing table and a drive mounted on the support frame of the swing mechanism, an electromagnetic stirring inductor located at the exit of the mold, and also the guide section of the roller wiring of the stream mounted on the support frame of the swing mechanism, the drive of the swing mechanism of the mold it is full in the form of a hydraulic cylinder, while the supporting frame is located below the electromagnetic stirring inductor and is made of a closed ring shape that does not interfere with the installation and dismantling of the inductor, and the swing table of the swing mechanism is made in a U-shape, water-cooled, in the form of a water collector. In the swinging table, a window is made for disconnecting the hydraulic cylinder of the mold swinging mechanism.

Distinctive features of the proposed machine for continuous casting of billets from the above known, closest to it, is that the drive of the swing mechanism of the mold is made in the form of a hydraulic cylinder, while the support frame is located below the electromagnetic stirring inductor and is made of a closed ring shape that does not interfere with the mounting and dismounting of the inductor and the rocking table of the rocking mechanism is made U-shaped, water-cooled, in

in the form of a water collector. In the swinging table, a window is made for disconnecting the hydraulic cylinder of the mold swinging mechanism.

Due to the presence of these signs, a stable oscillation of the mold occurs on the leaf springs with a hydraulic drive. As a result, the trajectory of the mold is identical in each swing cycle and the surface quality of the cast billet is improved in the conditions of narrowed space on billet and bloom casting machines.

The U-shape of the swinging table allows you to set the electromagnetic stirring inductor in its working position through the open side.

Considering the fact that water and air are supplied to the mold through a rocking table, it is made in the form of a water-cooled collector to prevent its deformation.

In addition, a mold, an inductor and a guide section are installed on the support frame, this allows you to mount and dismantle the entire head part of the continuous casting machine, both during normal mold replacement and in emergency cases.

The proposed continuous casting machine is illustrated by the drawings shown in figures 1-3.

Figure 1 shows a General view of the head of the continuous casting machine;

figure 2 is the same top view (mold and guide section of the roller wiring is not shown);

figure 3 is the same, section aa.

The continuous casting machine comprises a mold 1, a swing mechanism of the mold 2 with longitudinal 3 and transverse 4 springs, compensating springs 5. The swing mechanism of the mold is equipped with a swing table 6 and a hydraulic cylinder 7 mounted on a supporting frame 8. The swing table 6 is made U-shaped

forms, water-cooled, in the form of a water collector. The supporting frame 8 is made of a closed annular shape that does not interfere with the installation and dismantling of the electromagnetic stirring inductor 9. The inductor 9 is located at the outlet of the mold 1 and above the supporting frame 8. A window 10 is made in the swing table 6 for quickly disconnecting the hydraulic cylinder 7 from the swing table connected to it the swing mechanism of the mold.

Below the mold 1, on the support frame 8 of the swing mechanism, a guide section of the roller wiring of the brook 11 is installed, which also does not interfere with the installation and dismantling of the electromagnetic stirring inductor 9.

Due to the fact that the mold 1 and the guide section 11 can be set relative to each other in the mechanical repair shop, when replacing the mold 1 is reinstalled without losing the accuracy of its exhibition and swing.

The mold 1 and the guide section 11 are set on the swing mechanism of the mold 2 in the mechanical repair shop and then installed on the continuous casting machine.

When dismantling the mold 1 with its subsequent installation and the electromagnetic stirring inductor 9 and re-installation of the mold 1 there is no loss of mutual accuracy of the exhibition of the mold and the guide section 11.

In emergency situations, the swing mechanism 2 is jointly dismantled together with the mold 1, the inductor 9 and the guide section 11.
