Referring to Fig.1-4, a kind of a kind of embodiment provided by the invention: the inside and outside combined type current stabilization of continuous casting triangle tundish
Device, including outer lining 1, outer lining 1 include pedestal 11, and the appearance of pedestal 11 is in the pentagon comprising two right angles, the top of pedestal 11
Deflector 12 is provided at the non-straight arm of angle, the appearance of deflector 12 is in inverted " v ", and the top of pedestal 11 is far from the one of deflector 12
End is provided with debris retaining plate 13, and pedestal 11, deflector 12, debris retaining plate 13 are an integral molding structure, set at the inside center of pedestal 11
It is equipped with liner 2, using white olivine by pouring, liner 2 can also be magnalium carbonaceous using magnesium carbonaceous and passes through machine outer lining 1
It presses.
The top surface of deflector 12 is higher than the top surface of debris retaining plate 13；The side outer wall both ends of debris retaining plate 13 are to separate
12 direction of deflector is shunk, and flume 16 is formed between the outer wall both ends of debris retaining plate 13 and two outer walls of deflector 12；Position
The top of pedestal 11 is formed with collection steel pond 14 by debris retaining plate 13, deflector 12, the encirclement of flume 16, collects the bottom interior wall in steel pond 14
Multiple unhurried current bands 15 are provided with, multiple unhurried current bands 15 as the center of circle at 2 top center of liner in ripples shape to be distributed；Liner 2 includes
Bucket 21 is impacted, the appearance for impacting bucket 21 is cylindrical, and the cross section for impacting bucket 21 is " U "-shaped, impacts the top surface of bucket 21
It is concordant with the top surface of pedestal 11, and the bottom interior wall for impacting bucket 21 is provided with circular protrusions 22, the inner wall of impact bucket 21 leans on
Proximal portion is provided with contraction edge 23；The inner wall of impact bucket 21 is fixedly connected there are two the ring 24 that flows slowly, two unhurried current rings 24 it is outer
Wall is provided through multiple through slots 25, and the quantity of multiple through slots 25 on each unhurried current 24 surface of ring is 12, and 12
Through slot 25 is circumferentially distributed.
Due to the difference of material and production method, the magnesium olive of the magnesium carbonaceous of machine pressure or magnalium carbide refractory than casting
Stone fire resistant materials have a clear superiority in terms of service performance.Compared with traditional integrated poured flow straightener, flow straightener of the present invention
It can be improved for 30% or more service life, reduce cost 20% or so, while volume reduces 20% or so.
Working principle: two adjoining outer walls of outer lining 1 from bottom to top extend outwardly, and form two inclined surface, can be with triangle
The inner wall of shape tundish closely agrees with, and molten steel directly pours at the top center of the circular protrusions 22 of impact 21 bottom of bucket, leads to
The cambered surface for crossing circular protrusions 22 changes the flow direction of molten steel, absorbs the impact force of molten steel, two unhurried current rings 24 can successively absorb molten steel
Remaining impact force, power potential energy sufficiently discharges when molten steel is flowed out by through slot 25, and contraction edge 23 is splashed outward preventing molten steel
While, the thickness of impact 21 top edge of bucket is increased, to effectively extend the service life of liner 2, is overflow from impact bucket 21
Molten steel out flows into tundish after entering collection steel pond 14 through flume 16, and the unhurried current band 15 on collection 14 surface of steel pond further slows down
The flow velocity of molten steel makes the field trash in molten steel have the sufficient time to float in collection steel pond 14；Debris retaining plate 13 can will be most absolutely
Number residue intercepts, and liner 2 uses magnesium carbonaceous or magnalium carbide refractory, and excellent anti-erosion, antiscour feature improve
Service life of flow straightener and reducing is mingled with caused by molten steel；Outer lining 1 is passed through using white olivine to be poured, at low cost
While improve the flow field of tundish；For the Rong Gangliang for increasing tundish, the liner 2 of flow straightener of the present invention is using machine pressure side
The Gao Timi bulk containers that formula is produced reduce flow straightener volume under same weights；Preferably to adapt in triangle
Between the flow pattern that wraps, flow straightener of the present invention proposes design scheme specifically for triangle tundish, makes the application of flow straightener more
Add specialization.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features,
