The rising-hole brick with vortex vanes, as an important part of the one-way solidification device, can effectively control the flowing state of pouring flow, guarantees the ultimate quality of casting blanks, and will be extensively used in the manufacturing of extra-thick slabs.
Description
Technical field
The utility model relates to a kind of rise hole brick that has swirl vane, and this brick is a vitals of producing the unidirectional solidification device that extra-thick plate blank uses.
Background technology
The unidirectional solidification technology is a die casting technology of producing extra-thick plate blank that grows up the eighties in last century, is applicable to that production is super-huge, internal soundness even, nothing is loose and the extra-thick plate blank of segregation.
The manufacture order of present industrial use mostly is bottom running to the technology of coagulated ingot.Chinese patent 93238966.X and Japan Patent JP5606363 disclose a kind of bottom running unidirectional solidification device respectively, molten steel injects ingot mould by the last orifice on the cooling chassis, cooling is forced in the steel ingot bottom, and oppose side wall and top are incubated, and column crystal is grown vertically upward.
In order to obtain high-quality extra-thick plate blank, generally all adopt the high temperature and high speed cast in process of production.And the through-type orifice brick of going up that is adopted in the present industrial production; can't control effectively to the beam flow regime; in casting process, can form strong impulsive force to the molten steel surface; above the sprue gate, form a very high rising head; cause covering slag to be involved in the formation inclusion defect; and can't avoid high-temperature steel stream that cooling chassis and ingot mould sidewall heat-insulating material are formed the very strong power of washing away, cause the melting loss of water-cooled chassis and sidewall heat-insulating material.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model is to provide a kind of rise hole brick that has swirl vane, realizes molten steel flow regime in the unidirectional solidification casting process is effectively controlled, and guarantees device security and strand final mass.
The utility model is achieved in that a kind of rise hole brick that has swirl vane, is installed on the center of unidirectional solidification device water-cooled chassis plug hole, and described rise hole brick integral body is cylindrical shape, and cylindrical cavity is a whole butterfly swirl vane.
Described rise hole brick is made with high alumina refractories.
The utility model is owing to adopt above-mentioned structure; compare with existing through-type hole; advantage of the present utility model is: the flow through swirl vane of rise hole brick of molten steel; form strong rotational flow in rise hole brick chamber and in the ingot mould; not only can reduce impulsive force to molten steel surface, chassis and sidewall refractory material; effectively prevent the melting loss with chassis and sidewall heat-insulating material of being involved in of field trash; and strong eddy flow can promote that the collision of the field trash protected slag of growing up is adsorbed, improves the degree of purity of molten steel.
Description of drawings
The rise hole brick that Fig. 1 has a swirl vane for the utility model is installed on the position view of unidirectional solidification device;
Fig. 2 the utility model has the rise hole brick structure schematic diagram of swirl vane.
Among the figure: 1 gate spool, 2 water-cooled chassis, 3 chassis of making a bet, 4 runner bricks, 5 have the rise hole brick of swirl vane, 6 covering slags, 7 ingot moulds, 8 heat-insulating materials, 9 molten steel (molten steel), 10 swirl vanes.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of rise hole brick 5 that has swirl vane is installed on the center of unidirectional solidification device water-cooled chassis 2 plug holes.Referring to Fig. 2, described rise hole brick 5 integral body are cylindrical shape, and cylindrical cavity is a whole butterfly swirl vane 10, and rise hole brick 5 usefulness high alumina refractories are made.Space between described rise hole brick 5 and water-cooled chassis 2 plug holes is filled up with nail iron.
Referring to Fig. 1, during industrial production, molten steel is poured into by gate spool 1 with the speed of 5t/min, molten steel the runner brick 4 in the chassis 3 of making a bet of flowing through, produce strong eddy flow when passing through the rise hole brick 5 that has rotating vane at a high speed then, molten steel 9 enters into and continues to keep rotatablely moving at a high speed in the ingot mould 7, and high rotation speed can reach 5m/s.Molten steel 9 strong eddy flows can form very strong turbulent flow with ingot mould 7 inside in rise hole brick 5, the collisions that help folder nonmetal impurities in the molten steel 9 are grown up, and final protected slag 6 absorbs, after measured Al in the covering slag 6
2O
3Content has increased by 30%, has purified molten steel 9, has guaranteed slab quality.Beam rotatablely moves turbulence intensity has been increased; and the movement locus that makes beam arrive molten steel 9 surfaces increases; because the effect of molten steel viscous force; beam kinetic energy weakens greatly; make the height of rising head reduce by 50%; weaken liquid fluctuating, prevented being involved in of covering slag 6, and reduced the melting loss of water-cooled chassis 2 and sidewall heat-insulating material 8.And beam rotational flow in ingot mould 7 makes the temperature of molten steel 9 more even, helps the growth vertically upward of column crystal, improves the final mass of strand.
The good effect that the utility model produces can embody from the following aspects:
1, uses the rise hole brick of band swirl vane; beam forms very strong rotatablely moving with ingot mould inside in last orifice brick chamber, the collision that strong turbulent flow helps to press from both sides nonmetal impurities is grown up, and final protected slag absorbs; the removal efficient of field trash improves 30%, has purified molten steel.
2, use the rise hole brick of band swirl vane, effectively weakened the impulsive force of beam, make riser height reduce by 50%, effectively prevent being involved in of field trash, and reduce the melting loss of chassis and sidewall heat-insulating material liquid level, chassis and sidewall heat-insulating material.
3, beam rotational flow in ingot mould makes the temperature of molten steel more even, helps the growth vertically upward of column crystal, improves the final mass of strand.
The utility model can effectively be controlled the flow regime of beam as unidirectional solidification device vitals in casting cycle, guarantee the strand final mass, will be applied to widely in the production process of extra-thick plate blank.
