Abstract
The utility model discloses a kind of strand ultrasonic resonance device, this strand is located at continuous caster roller way, including ultrasonic generator, ultrasonic power amplifying device and several ultrasonic transmission devices, described ultrasonic generator is produced ultrasound wave and is amplified by ultrasonic power amplifying device, it is then passed to and does a ultrasonic transmission device, ultrasonic transmission device is located between adjacent continuous caster roller way, and ultrasonic transmission device is located on apparatus capable of fluctuating.A kind of strand ultrasonic resonance device of the present utility model, makes the internal two-phase section of strand produce resonance by ultrasound wave, and " the bridging phenomenon " occurring during destroying casting blank solidification, thus reducing the loose phenomenon of strand, improves slab quality.
Description
Technical field
This utility model is related to strand ultrasonic resonance device, belongs to slab quality control field.
Background technology
In casting process, because different phase intensity of cooling is different, strand is followed successively by little etc. from edge to center strand
Axialite body band, column crystal zone and Center Equiaxial Crystal band.After going out crystallizer, surface forms green shell to generous strand, but liquid core
Still very long, after strand enters cooling twice section, because casting billet surface intensity of cooling is uneven, cause the office that intensity of cooling is big
Portion region column crystal is first developed, and when the column crystal on both sides is connected or equiax crystal falls to being caught by column crystal, arises that and " puts up a bridge
Phenomenon ".At this moment the molten steel of liquid core is separated by " solidification bridge ", the contraction that under bridge, remaining molten steel produces because of solidification, cannot get on bridge
The supplement of molten steel, ultimately forms trickle hole, referred to as loose.
Dispersed and distributed is referred to as General Loosen in the hole of whole section, and in the space of branch intergranular, referred to as dendrite is loose, casting
Base approximate centerline space be referred to as center porosity.General Loosen and the loose all energy seam during frying of dendrite, have only
Center porosity, with obvious center segregation phenomenon, is unable to seam completely after rolling, when center porosity and center segregation are serious, also
Centre burst can be led to, have a strong impact on slab quality.
Strand secondary cooling zone electromagnetic agitation and solidification end soft reduction technique all can effectively reduce strand center porosity at present, from
And improve slab quality.
Utility model content
Utility model purpose：In order to overcome the deficiencies in the prior art, this utility model provides a kind of strand ultrasonic
Ripple resonance device, makes the internal two-phase section of strand produce resonance by ultrasound wave, occur during destroying casting blank solidification " puts up a bridge existing
As ", thus reducing the loose phenomenon of strand, improve slab quality.
Technical scheme：For solving above-mentioned technical problem, a kind of strand ultrasonic resonance device of the present utility model, this strand
Positioned at continuous caster roller way, including ultrasonic generator, ultrasonic power amplifying device and several ultrasonic transmission devices, institute
State ultrasonic generator generation ultrasound wave to amplify by ultrasonic power amplifying device, be then passed to and do a ultrasound wave and send out
Injection device, ultrasonic transmission device is located between adjacent continuous caster roller way, and ultrasonic transmission device is located on apparatus capable of fluctuating.
Preferably, described apparatus capable of fluctuating comprises base, sleeve and elevating lever, described elevating lever is inserted in sleeve,
Elevating lever is fixed by locking device.
Preferably, the top of described elevating lever is provided with mounting disc by flange, mounting disc is provided with several installations
Hole, ultrasonic transmission device is arranged in mounting disc.
Preferably, described locking device comprises clamping screw, described bolt by being threadably mounted on sleeve, by rotation
Elevating lever locked by dynamic bolt.
Beneficial effect：Strand ultrasonic resonance device of the present utility model, makes the internal two-phase section of strand produce by ultrasound wave
Raw resonance, " the bridging phenomenon " occurring during destroying casting blank solidification, thus reducing the loose phenomenon of strand, improves slab quality；
But also the distance between ultrasonic transmission device and strand can be adjusted by liftable support, reasonably do not know that ultrasound wave is sent out
The distance between injection device and strand are so that slab quality is the most preferable.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of apparatus capable of fluctuating in Fig. 1.
Specific embodiment
As depicted in figs. 1 and 2, a kind of strand ultrasonic resonance device of the present utility model, this strand 2 is located at caster roll
Road 1, including ultrasonic generator 4, ultrasonic power amplifying device 5 and several ultrasonic transmission devices 6, described ultrasound wave
Generating meanss 4 are produced ultrasound wave and are amplified by ultrasonic power amplifying device 5, are then passed to and do a ultrasonic transmission device
6, ultrasonic transmission device 6 is transmitting probe, and ultrasonic transmission device 6 is located between adjacent continuous caster roller way 1, transmitting probe
Layout area is at straightening section of continuous casting machine, and ultrasonic transmission device 6 is located on apparatus capable of fluctuating.
In this utility model, described apparatus capable of fluctuating comprises base 71, sleeve 72 and elevating lever 74, described elevating lever 74
It is inserted in sleeve 72, elevating lever 74 is fixed by locking device.The top of described elevating lever 74 is provided with installation by flange
Disk 75, mounting disc 75 is provided with several installing holes, and ultrasonic transmission device 6 is arranged in mounting disc 75.Described locking device
Comprise clamping screw 73, described bolt 73, by being threadably mounted on sleeve 72, locks elevating lever 74 by turn bolt.
When strand conticaster works, ultrasonic generator 4 produces the ultrasound wave of certain frequency, and ultrasonic power amplifies
Ultrasonic power is amplified by device 5, and finally by ultrasonic transmission device 6 by ultrasound wave directive strand 2, ultrasound wave is through casting
Base 2 reaches strand two-phase section 3.Make the frequency of ultrasound wave and two-phase section 3 molten steel of generation by adjustment ultrasonic generator 4
Natural frequency is close, makes molten steel in two-phase section produce slight vibration in the presence of ultrasound wave, the slight vibration of molten steel can have
Effect interrupts " solidification bridge ", thus improving Inner Quality of Billet.
The above be only preferred implementation of the present utility model it should be pointed out that：Common skill for the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
