Further, the flow direction of the cooling water flow conduits is perpendicular to casting nozzle body length direction.
Beneficial effect using above-mentioned further scheme is: setting cooling water flow conduits are conducive to improve on the outside of cooling wall
The cooling velocity of molten metal, cooling water are flowed along roll axial direction, not only make the molten metal in molten metal circulation passage can
To be fully cooled, and injects and be discharged convenient for cooling water, it is simple to operate.
Further, the molten metal circulation passage is the curved channel adapted to roller surface.
Further, the casting nozzle ontology is equal with the even width of molten metal circulation passage that roll is formed, mobile casting nozzle
Width of the ontology close to or far from roller central line adjustment molten metal circulation passage.
Beneficial effect using above-mentioned further scheme is: using the runner of arcuate structure, being conducive to cooling wall and roll
Outer wall forms molten metal circulation passage in homogeneous thickness, so that molten metal uniformly flows cooling, and uses arcuate structure, adjusts
Section casting the distance between nozzle ontology and roller central line just can adjust the thickness of molten metal circulation passage, adjust side easy to operate
Just.

Specific embodiment
Illustrate embodiments of the present invention below by way of specific specific example, those skilled in the art can be by this specification
Other advantages and efficacy of the present invention can be easily understood for disclosed content.The present invention can also pass through in addition different specific realities
The mode of applying is embodied or practiced, the various details in this specification can also based on different viewpoints and application, without departing from
Various modifications or alterations are carried out under spirit of the invention.
It should be noted that cited such as "upper", "lower", "left", "right", "front", "rear" " centre " in this specification
And the term of " one " etc., it is merely convenient to being illustrated for narration, rather than to limit the scope of the invention, relativeness
Be altered or modified, under the content of no substantial changes in technology, when being also considered as the enforceable scope of the present invention.
As depicted in figs. 1 and 2, nozzle is cast in casting of the invention, applied to double rod castings of strip, including casting nozzle ontology 5, casting
The two sides of nozzle ontology 5 be equipped with molten metal runner 2, casting 5 two sides of nozzle ontology be provided with casting nozzle wall 1, casting nozzle wall 1 and casting nozzle ontology 5 it
Between formed molten metal runner 2.It casts and forms two metals corresponding with molten metal runner 2 between 5 front of nozzle ontology and two rolls 6
Liquid stream circulation passage 8, two molten metal circulation passages 8 converge in front of casting nozzle ontology 5.The front for casting nozzle ontology 5 is conduction part, is drawn
Cooling water flow conduits 4 are provided in stream portion, the periphery of conduction part is provided with cooling wall 3, is formed between the cooling wall 3 and conduction part cold
But water flow passage 4 form molten metal circulation passage 8 between cooling wall 3 and two 6 surfaces of roll.Molten metal runner 2 and metal liquid stream
Circulation passage 8 is connected to, and molten metal flows through molten metal circulation passage 8 after being injected by two molten metal runners 2, and two molten metal circulations are logical
Molten metal in road 8 converge after again by passing through between two rolls 6, molten metal is in flow process, the note in the cooling water flow conduits 4
Enter cooling water, is conducive to the cooling efficiency for accelerating molten metal.
As depicted in figs. 1 and 2, conduction part two sides and 3 two sides of cooling wall are arc-shaped, and be adapted, conduction part by it is rear extremely
Preceding width is gradually reduced, and the molten metal circulation passage that cooling wall 3 and roll 6 are formed is the curved channel adapted to 6 surface of roll,
The arc drainage for realizing molten metal casts the molten metal circulation passage 8 that nozzle ontology 5 and roll 6 are formed using the channel of arcuate structure
Even width it is equal, be conducive to molten metal uniform thickness flowing, molten metal is uniformly cooled down.Cast nozzle ontology 5 from back to front
Width is gradually reduced, the setting casting of molten metal runner 25 rear portion two sides of nozzle ontology.
As shown in Fig. 2, one of roll 6 is located at the underface of another roll 6, the axial direction of two rolls 6 is set in parallel
It sets, casting nozzle ontology 5 is mounted between two rolls 6, moves horizontally casting nozzle ontology 5 roll centre common close to two rolls 6
When line 9, the width of molten metal circulation passage 8 reduces, i.e. the circulation thickness of molten metal is thinning；It is separate to move horizontally casting nozzle ontology 5
When two 6 common roller central lines 9 of roll, the width of molten metal circulation passage 8 increases, i.e., the circulation thickness of molten metal becomes
Thickness is conveniently adjusted the width of molten metal circulation passage 8 using the design structure, so as to adjust the circulation thickness of molten metal, improves
The cooling efficiency of molten metal, it is simple to operate.
As shown in Fig. 2, length direction of the flow direction of cooling water flow conduits 4 perpendicular to casting nozzle ontology 5, i.e., cooling water is along roll 6
Axial direction flowing.Cooling water is flowed by one end of cooling water flow conduits 4, and is flowed out by the other end of cooling water flow conduits 4, cooling
Water flow passage 4 carries out supplement heat rejecter to the molten metal in molten metal circulation passage 8, improves cooling efficiency.
The present invention makes the thickness of molten metal thinning by the way that two molten metal circulation passages 8 are arranged, and improves the cold of molten metal
But efficiency, while rectified action is played to molten metal, it prevents molten bath inner metal liquid Flow Field Distribution chaotic, improves product quality.Gold
Belong in the liquid process of circulation and be close to roller surface, is conducive to molten metal and is quickly cooled down, prevent liquid core length in metal bath too long, and
Cooling water flow conduits 4 are cooperated to pass through the stream of cooling water so that cooling water and molten metal are located at the inner side and outer side of cooling wall 3
