Abstract
The utility model discloses a spray nozzle ladle of equipment for producing an amorphous ribbon. The spray nozzle ladle comprises a spray nozzle ladle body, wherein a spray nozzle is arranged at the lower part of the spray nozzle ladle body; a protective gas spray port is arranged in the spray nozzle and is consistent with the spray nozzle in direction; burning gas flame is sprayed from the protective gas spray port while the spray nozzle sprays molten steel; the flame is used for heating a weld pool formed by the molten steel sprayed by the spray nozzle; and the protective gas spray port is positioned in the edge of the spray nozzle. According to the spray nozzle ladle, the heating is realized by adopting the protective gas flame, so that air current brought by the cooling roller instantly expands after reaching a flame area and the volume density of air is reduced, and thus the cooling effect of the molten steel and the cooling roller is improved and the oxidation of spray nozzle materials and the molten steel is reduced.
Description
Technical field
The utility model relates to the amorphous thin ribbon manufacturing technology, 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 decrease of temperature, and lines up in an orderly manner according to certain crystalline state rule at leisure, forms crystal.If cooling procedure is very fast, atom also has little time just to arrange again and has been solidified, and has just produced amorphous alloy thus, and amorphous alloy is compared with crystal alloy, in physical property, chemical property and mechanical properties significant variation has taken place all.With the ferro element is that main amorphous alloy is an example, and it has high saturated magnetic induction and low-loss characteristics.Because such characteristic, amorphous alloy material has possessed wide application space in various fields such as electronics, Aeronautics and Astronautics, machinery, microelectronics.For example, be used for aerospace field, can alleviate power supply, weight of equipment, increase payload.Be used for civilian electric power, electronic equipment, can dwindle power volume greatly, raise the efficiency, strengthen antijamming capability.Minitype iron core can be widely used in the transformer among the ISDN ISDN.Amorphous ribbon is used for making the sensor tag of supermarket and library's burglary-resisting system.The effect that non-crystaline amorphous metal is magical has vast market prospect.
The preparation amorphous alloy adopts the technology of rapid solidification; The high-temperature molten steel that will be in molten condition is ejected on the chill roll of rotation at a high speed; Molten steel cools off rapidly with the speed of per second 1,000,000 degree, only just 1300 ℃ molten steel is dropped to below 200 ℃ the formation amorphous band with time of signa.Chill roll is when rotating at a high speed; There is layer of air stream on its surface; Air stream is brought under the molten steel weld pool, the thermal resistance between molten steel and the chill roll is increased, so influenced the thermal conductivity of molten steel; Thereby the effect that the molten steel chilling is formed amorphous band exerts an influence, and the molten steel of nozzle and weld pool at high temperature contacts with air and can produce oxidation.
The utility model content
The purpose of the utility model provides a kind of nozzle bag of amorphous thin ribbon producing equipment, reduces the oxidation of nozzle and molten steel.
The utility model is that the technical scheme that its technical problem of solution is adopted is,
The nozzle bag of amorphous thin ribbon producing equipment; Comprise nozzle bag body, the bottom of this nozzle bag body has nozzle, has the protective gas spout on the said nozzle; The protective gas spout is consistent with the direction of this nozzle; In nozzle ejection molten steel, the gas flame of protective gas spout ejection burning, flame heats the weld pool that nozzle ejection molten steel forms;
Said protective gas spout is positioned at the edge of nozzle.
The advantage of the utility model is; This nozzle bag adopts protective gas flame heat, and the air that chill roll is brought flows to and reaches instantaneous expansion behind the flame region, and volume of air density reduces; Thereby promote the cooling effect of molten steel and chill roll, reduce the oxidation of nozzle material and molten steel.
Description of drawings
Fig. 1 is the structural representation of the nozzle bag of the utility model proposition.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As shown in Figure 1; The nozzle bag of the amorphous thin ribbon producing equipment that the utility model proposes comprises nozzle bag body 1, and the bottom of this nozzle bag body 1 has nozzle 2, has protective gas spout 3 on the said nozzle 2; Protective gas spout 3 is consistent with the direction of this nozzle 2; In nozzle 2 ejection molten steel, the gas flame of protective gas spout 3 ejection burnings, flame heats the weld pool 5 that nozzle 2 ejection molten steel form;
Further, said protective gas spout 3 is positioned at the edge of nozzle 2.
This nozzle bag adopts protective gas flame heat, and the air that chill roll is brought flows to and reaches instantaneous expansion behind the flame region, and volume of air density reduces, thereby promotes the cooling effect of molten steel and chill roll, the oxidation of minimizing nozzle material and molten steel.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
