Abstract
The utility model discloses a nozzle bag of an amorphous thin belt producing device and belongs to the technical field of amorphous thin belt producing. According to the technical scheme, the nozzle bag of the amorphous thin belt producing device comprises a nozzle bag body and is characterized in that a fluid inlet is formed at the top of the nozzle bag body; a channel is formed inside the nozzle bag body; four boron nitride ceramic chips are arranged at the bottom of the nozzle bag body; a 0.1mm to 1.0mm spraying seam is defined by the four boron nitride ceramic chips; the peripheries of the boron nitride ceramic chips are fixedly connected with the nozzle bag body through refractory mortar; the boron nitride ceramic chips are connected with screws; three protection air spraying openings are formed on the left side boron nitride ceramic chips; the protection air spraying openings are formed on the edge of the spraying seam. Compared with the prior art, the nozzle bag of the amorphous thin belt producing device which is heated through protection air flames enables air flows brought through a cooling roller to be instantly swelled after achieving a flame area, the air volume density is reduced, and accordingly the cooling effects of molten steel and the cooling roller are improved and oxidation of the molten steel is reduced.
Description
Technical field
The utility model relates to amorphous thin ribbon manufacturing technology field, relates in particular to a kind of nozzle bag of amorphous thin ribbon producing equipment.
Background technology
Metal is after fusing, and inner atom is in active state, once metal begins to cool down, atom will be along with the decline of temperature, and according to certain crystalline state rule, line up in an orderly manner at leisure, forms crystal.If cooling procedure is very fast, atom also has little time just to rearrange to be solidified, and has just produced thus amorphous alloy, and amorphous alloy is compared with crystal alloy, in physical property, chemical property and mechanical properties, significant variation has all occurred.The amorphous alloy that the ferro element of take is master is example, and it has high saturated magnetic induction and low-loss feature.Due to such characteristic, amorphous alloy material has possessed wide application space in the various fields such as electronics, Aeronautics and Astronautics, machinery, microelectronics.For example, for aerospace field, can alleviate power supply, weight of equipment, increase payload.For civilian electric power, electronic equipment, can greatly dwindle power volume, raise the efficiency, strengthen antijamming capability.Minitype iron core can be widely used in the transformer in ISDN ISDN.Amorphous ribbon is used for manufacturing the sensor tag of supermarket and library's burglary-resisting system.The effect of non-crystaline amorphous metal mystery, has wide market prospects.
Prepare the technique that amorphous alloy adopts rapid solidification, high-temperature molten steel in molten condition is ejected on the chill roll of High Rotation Speed, molten steel is cooling rapidly with the speed of 1,000,000 degree per second, only with the time of signa, just the molten steel of 1300 ℃ is dropped to below 200 ℃, forms amorphous band.Chill roll is when High Rotation Speed, there is one deck air stream on its surface, air stream is brought under molten steel weld pool, thermal resistance between molten steel and chill roll is increased, therefore affected the thermal conductivity of molten steel, thereby the effect that molten steel chilling is formed to amorphous band exerts an influence, the molten steel of nozzle and weld pool at high temperature contacts with air and can produce oxidation.
Utility model content
The purpose of this utility model is the deficiency existing for prior art, provides a kind of nozzle bag of amorphous thin ribbon producing equipment, to reduce the oxidation of molten steel.
The purpose of this utility model is achieved through the following technical solutions: a kind of nozzle bag of amorphous thin ribbon producing equipment, comprise nozzle bag body, described nozzle bag bodies top is provided with inlet, in nozzle bag body, be provided with runner, nozzle bag body bottom is provided with four boron nitride ceramics sheets, described four boron nitride ceramics sheets surround the spray seam of 0.1mm-1.0mm, four boron nitride ceramics sheet peripheries are fixedly connected with nozzle bag body by fire clay, boron nitride ceramics sheet connecting screw rod, on the boron nitride ceramics sheet in left side, be provided with three protective gas spouts, described protective gas spout is positioned at the edge of spray seam.
The beneficial effects of the utility model are: the utility model adopts the heating of protective gas flame; make air stream that chill roll brings arrive instantaneous expansion after flame zone; volume of air density reduces, thereby promotes the cooling effect of molten steel and chill roll, reduces the oxidation of molten steel.

Wherein, 1-nozzle bag body; 2-inlet; 3-runner; 4-boron nitride ceramics sheet; 5-spray seam; 6-fire clay; 7-screw rod; 8-protective gas spout; 9-weld pool.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
By accompanying drawing 1-Fig. 2, can find out, the nozzle bag of the amorphous thin ribbon producing equipment of this programme, comprise nozzle bag body 1, described nozzle bag body 1 top is provided with inlet 2, in nozzle bag body 1, be provided with runner 3, nozzle bag body 1 bottom is provided with four boron nitride ceramics sheets 4, described four boron nitride ceramics sheets 4 surround the spray seam 5 of 0.1mm-1.0mm, four boron nitride ceramics sheet 4 peripheries are fixedly connected with nozzle bag body 1 by fire clay 6, boron nitride ceramics sheet 4 connecting screw rods 7, on the boron nitride ceramics sheet 4 in left side, be provided with three protective gas spouts 8, described protective gas spout 8 is positioned at the edge of spray seam 5, in spray seam 5 ejection molten steel, the gas flame of protective gas spout 8 ejection burnings, the weld pool 9 that flame forms the molten steel of spray seam 5 ejections heats.The utility model adopts the heating of protective gas flame, makes air stream that chill roll brings arrive instantaneous expansion after flame zone, and volume of air density reduces, thereby promotes the cooling effect of molten steel and chill roll, the oxidation of minimizing molten steel.
Disclosed is above only a preferred embodiment of the present utility model; but be not limited to the utility model; all within spirit of the present utility model and principle; the modification of doing, polish, be equal to replacement etc.; within all should being included in protection domain of the present utility model; in addition, the utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
