Abstract
The utility model relates to an ultrasonic wave processing device for molten steel in a crystallizer of a conticaster, which belongs to the technical field of the ferrous metallurgy. The processing device comprises a supersonic generator connected to a power supply as well as a guide wave bar, wherein the output terminal of the supersonic generator is connected with the guide wave bar via a cumulative rod. Thus, the guide wave bar can be directly inserted into the crystallizer in the conticaster while casting the molten steel, so as to apply a strong ultrasonic wave field to the molten steel inside the crystallizer and perform ultrasonic wave process to molten steel not solidified inside casting blanks, resulting in great enhancement of effect of the ultrasonic wave; the grain structure in the cast state of continuous casting billets are fined, the equiaxed crystal ratio is improved, and cracks inside the continuous casting billets are reduced.
Description
Technical field
The utility model relates to a kind of molten steel treating apparatus, and especially a kind of conticaster crystallizer molten steel ultrasonic treatment unit belongs to technical field of ferrous metallurgy.
Background technology
The equiaxial crystal ratio that improves continuous casting billet can improve the high-level steel grades such as uniformity, particularly pipe line steel, electrical sheet and stainless steel of steel performance.Continuous casting billet equiaxial crystal ratio generally speaking has only about 15%, for improving the equiaxial crystal ratio of continuous casting billet, iron and steel metallurgical industry has carried out various trials, the conventional method that adopts mainly also has pulse current facture, ultrasonic wave facture except that forming core particle method, high-intensity magnetic field facture---and promptly adopt ultrasonic wave to handle low-melting non-ferrous metal by chamber wall.
Understand according to the applicant, domestic applications number are that 200410103904.3,01134145.9,200510036555.2 patent application relates to the ultrasonic wave treatment technology, but are used for aluminium alloy preparation or inclusion removal substantially.Foreign patent such as US5018688A, JP55040056A, JP56026562A, JP62130211A, EP0879896A1, DE69609970D, DE69619866D etc. also relate to the ultrasonic wave treatment technology, are mainly used on the liquid steel refining of refining equipment.But above-mentioned technology all adopts ultrasonic wave to handle by chamber wall, so the ultrasonic wave importing is bad, and treatment effect is restricted.
The utility model content
The purpose of this utility model is: the deficiency at above-mentioned prior art exists proposes a kind of conticaster crystallizer molten steel ultrasonic treatment unit that can significantly improve treatment effect.
In order to reach above purpose, conticaster crystallizer molten steel ultrasonic treatment unit of the present utility model contains the supersonic generator that connects power supply, also contains the guided wave rod, and the output of described supersonic generator connects the guided wave rod by the cumulative bar.
Like this, can when the casting molten steel, the guided wave rod directly be inserted in the conticaster crystallizer,, not solidified molten steel in the strand is carried out ultrasonic wave handle, greatly increased the action of ultrasonic waves effect applying the intense ultrasonic wave field in the molten steel in the crystallizer.Make the as-cast structure grain refinement of continuous casting billet, improve equiaxial crystal ratio, reduce the continuous casting billet underbead crack.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
The specific embodiment
Embodiment one
The continuous casting mold molten steel ultrasonic treatment unit of present embodiment as shown in Figure 1, wherein power supply 1, supersonic generator 2, cumulative bar 3, guided wave rod 4 connects lead 5, molten steel 6, conticaster crystallizer 7 and solidified the strand shell, submersed nozzle 8.
The supersonic generator 2 of this treating apparatus connects power supply 1 by connecting lead 5, its ultrasonic wave takes place to hold the cumulative bar of making by alloy aluminum 3 to connect the guided wave rod 4 of graphite material, therefore the 2000W ultrasonic wave that is produced can be through cumulative bar 3, again by immersing the guided wave rod 4 in the molten steel, directly import in the high-temperature molten steel 6 in the conticaster continuous cast mold, in molten steel, add the intense ultrasonic wave field, handle not solidified molten steel with ultrasonic wave.
Hyperacoustic vibration effect has reduced axially loose and strand columnar zone greatly, enlarges its equiax crystal district, and crystal grain and carbide size are reduced.Ultrasonic vibration can be applied in the motion process of continuous casting billet shell simultaneously, obviously improves lubricating status, reduces the friction of steel and crystallizer wall, and surface quality of continuous castings is significantly improved.
It is guided wave rod matrix that present embodiment adopts the graphite material of 1700 ℃ of heatproofs, can anti-molten steel, the high temperature erosion of slag, can transmit ultrasonic wave again.In case of necessity, can be with two supersonic generator parallel connections, thus make the ultrasonic power maximum that adds in the molten steel can reach 4000W, greatly increased the action of ultrasonic waves effect, the straight carbon steel continuous casting billet equiaxial crystal ratio after ultrasonic wave is handled can reach more than 50%.
Claims (3)
1. a conticaster crystallizer molten steel ultrasonic treatment unit contains the supersonic generator that connects power supply, it is characterized in that: also contain the guided wave rod, the output of described supersonic generator connects the guided wave rod by the cumulative bar.
2. conticaster crystallizer molten steel ultrasonic treatment unit according to claim 1 is characterized in that: described guided wave rod is matrix with graphite.
3. conticaster crystallizer molten steel ultrasonic treatment unit according to claim 2, it is characterized in that: described supersonic generator is by at least two parallel connections.
