Description

Continuous casting vibration supporting roller with eccentric rotating piece and equipment thereof

Technical Field

The invention belongs to the field of metal solidification and continuous casting, and particularly relates to a continuous casting vibration support roller with an eccentric rotating piece.

Background

With the development of world metallurgical technology, modern continuous casting technology is continuously improved, the types of castable steel are continuously expanded, and some high-alloy and high-quality special steels are continuously produced in the continuous casting production flow of large-scale iron and steel enterprises. In order to solve the problems of solidification segregation, shrinkage cavity defects and the like of special steel, metallurgical technologists develop a plurality of patents and technologies in the aspect of the technology for a long time. At present, the electromagnetic stirring technology and the solidification tail end light pressing or casting rolling technology are mainly applied to industrial production in a large scale.

The electromagnetic stirring technology such as crystallizer electromagnetic stirring is that an electromagnetic induction coil or a stirrer is placed at the outer side of a continuous casting crystallizer, when alternating current with certain frequency is introduced into the electromagnetic induction coil or the stirrer, an electromagnetic field is generated, the magnetic field penetrates through a crystallizer copper plate and a metal solidified shell and generates induced current in liquid metal, the liquid metal is equivalent to a current carrier, the current carrier is acted by the magnetic field to generate electromagnetic force in the current carrier, so that the liquid metal generates forced convection, the flowing liquid metal scours the front edge of the solidified shell and breaks and crushes dendrites, and the broken and crushed dendrites become cores for later isometric crystal growth, so that the aim of improving the isometric crystal rate of a casting blank by the electromagnetic stirrer is fulfilled.

The application of the electromagnetic stirrer is an effective method for improving the internal quality of a casting blank. Firstly, the electromagnetic stirring is easy to cause the casting blank to generate a white bright band or a negative segregation band, thereby influencing the uniformity of the casting blank performance; and secondly, the energy loss of the electromagnetic stirrer after penetrating through the metal billet shell is large, and the energy loss of the electromagnetic field after penetrating through the metal shell is larger along with the thickening of the continuous casting billet shell. The effect of the electromagnetic stirrer on the solidification end position of the cast strand is less pronounced than when the electromagnetic stirrer is placed in the mold.

Thereby, a solidification end soft reduction technology is developed. The method is characterized in that the core of a casting blank which is not completely solidified is compacted by a mechanical deformation method so as to improve the core segregation of the casting blank. However, the solidification end of the cast slab is subjected to a large reduction force, which tends to cause reduction cracking.

In recent years, new methods for effectively improving defects such as segregation, porosity and shrinkage at the center of a cast slab have appeared. For example, the invention patent 'a method for improving the quality of a continuous casting slab and a vibration supporting roller device' previously filed by the applicant of the present application (application No.200410069058.8, granted No. CN 1256203C); and 'a control device for casting blank quality and improving middle and later stage solid-liquid two-phase region fluidity in the continuous casting solidification process' CN208116707U, the documents give out that the vibration mode is adopted to apply the vibration force to the solidified blank shell, and the purpose is to promote the fracture of dendrite at the solidification front in the blank shell and increase the central isometric crystal rate of the casting blank; on the other hand, defects such as segregation, porosity, and shrinkage at the center of the cast slab are improved at the final stage of solidification. However, the above patents only provide technical ideas, and do not provide structural solutions for devices to achieve the above functions. Particularly, on the premise that the supporting function of the vibration supporting roller is ensured by what structure, effective vibration of the solidified shell becomes a technical problem to be solved urgently.

Detailed Description

The invention is further described below with reference to the figures and various embodiments.

Example 1-eccentric rotary member is an eccentric bushing provided at both ends of a rotary shaft 5

Referring to fig. 1-2, the continuous casting vibration support roller with the eccentric shaft sleeve comprises a vibration support roller body 1, an end cover 2, a first bearing seat 3 and a first bearing 4 for supporting the roller body to rotate, a rotating shaft 5, the eccentric shaft sleeve 6, a second bearing seat 7 and a second bearing 8 for supporting the shaft to rotate, a bearing seat support 9, a coupling 10, a speed reducer 11, a motor 12, a base body rack 13, a speed reducer support 14, a motor support 15 and the like. When in use, the vibration supporting roller body 1 is in contact with the casting blank 16 and rotates along with the synchronous movement of the vibration supporting roller body and the casting blank; the key points are as follows: the motor 12 drives the rotating shaft 5 to rotate at a speed higher than that of the vibration supporting roller body 1, so that the vibration supporting roller body 1 vibrates in a direction perpendicular to the billet shell of the casting billet due to the existence of the eccentric shaft sleeve 6, and the billet shell of the casting billet 16 contacted with the vibration supporting roller body is stressed and vibrates. The rotation can break off the front ends of the dendrites at the front edge of the primary solidified blank shell in a large quantity and form a source of central isometric crystals; the cast slab at the later stage of solidification can also be treated to break coarse central equiaxed crystals and refine the solidification structure.

In order to obtain a good vibration effect of the vibration support roller, the rotation speed of the rotating shaft 5 is required to be 5 to 1500 times of the rotation speed of the vibration support roller body 1.

Similarly, to obtain a high rotation speed of the rotating shaft 5, an accelerator or a speed increaser may be used in the structure of the present invention. However, in the rear part of the casting machine, the shell of the cast slab is thick, and the vibration force must be increased for good vibration effect, and at this time, the rotation speed needs to be properly reduced by using a speed reducer to improve the ability to overcome the rotation resistance.

In order to improve the transmission effect, a driving motor 12 for vibrating the support roll may be placed at one end of the continuous casting vibrating support roll, see fig. 1; or placed at both ends of the continuous casting oscillating support roll, see fig. 2.

Example 2-eccentric rotating member is an eccentric mass 21 provided on the rotating shaft 5 inside the support roller

Referring to fig. 3, another way to realize the eccentric vibration of the vibration support roller is to directly arrange an eccentric mass 21 on the rotating shaft 5 in the inner region of the vibration support roller body 1 to vibrate the rotating shaft 5, and transmit the vibration to the vibration support roller body 1 to vibrate the vibration support roller body, wherein the weight of the eccentric mass 21 is 3% -40% of the weight of the vibration support roller body 1. In this case, the eccentric mass 21 may be integral with the rotary shaft 5, or may be mechanically fixed to the rotary shaft 5.

In order to obtain a good vibration effect, the bearing block bracket 9 may be rigid or elastic. Likewise, the coupling 10 may be a rigid coupling or an elastic coupling.

2) For the two-segment roller, a through shaft structure is adopted, a vibration supporting roller body 1 is arranged on one side, and a non-vibration supporting roller body 20 is arranged on the other side, as shown in fig. 5 a; it is also possible to have oscillating supporting roller bodies 1 on both sides, see fig. 5 b.

3) The sectional mode of the vibration supporting roller can also be other more sectional rollers, and the sectional mode and the combination of the vibration supporting roller can be suitable for more sectional roller structural forms.

4) For the supporting roller with the segmental structure, the two outer ends of the supporting roller can be respectively provided with the transmission motor, so that the rotating shaft of the supporting roller can be a through shaft, see fig. 2-5, or can be divided into two segments, see fig. 6.
