Abstract
The utility model relates to a water atomization injection device in the iron and steel milling technique, in particular to a high-pressure water atomization nozzle used for manufacturing iron and steel powders. The high-pressure water atomization nozzle is realized by the following technical measures that a nozzle intake, a base, an upper ring body, a lower ring body and a nozzle circular seam composed of the upper ring body and the lower ring body are included, wherein, a blowhole is arranged on a nozzle lug boss at the middle part of an inner cavity of the lower ring body. High pressure water forms a ring of water column after passing through the blowhole, so as to enable the gas flow in the nozzle to be more reasonable and the nozzle not to be obstructed easily, simultaneously, the functions of cooling and protecting powders and reducing the oxygen content of the iron and steel powders can be brought into play.
Description
Technical field
The utility model relates to the water atomization injection apparatus in the iron and steel powder-making technique, produces a kind of hydraulic atomized nozzle that steel powder is used specifically.
Background technology
In the production of iron and steel powder process, the atomizer in the water atomization injection apparatus all has very important influence for smooth and easy, the granularity of metal dust, oxygen content, the lumber recovery of atomization process.The Chinese patent name of this obligee application is called: (patent No. is a kind of hydraulic atomized nozzle: patent 00247583.9), a kind of hydraulic atomized nozzle is disclosed, wherein form the nozzle circumferential weld by upper ring body and lower ring body, the water under high pressure of process pressurization enters from the nozzle circumferential weld from the nozzle water inlet and sprays, nozzle circumferential weld area is little, and there is a fixed angle, forming a circle high-velocity flow is gathered together in the middle part, become the high pressure cascade of " inverted cone " type, the summit of circular cone is called " focus point ", steel ladle interior molten steel in top forms a diameter and fixes, when the stable molten steel that trickles flows down the position of falling " focus point ", water under high pressure is with the molten steel instantaneous trip, disperse, be cracked into small drop, fall into the pond of bottom, rapidly cooling, become small iron and steel particle, this process is called " atomizing ".But owing to form very big secondary nip in nozzle interior, gas flow is very unstable in the secondary nip, the molten steel particle is sticked on the inwall that encircles on the nozzle, cause spray nozzle clogging, atomizing can't be carried out, the steel powder quality instability of producing can not satisfy the instructions for use of high-performance powder product.
Summary of the invention
The purpose of this utility model provides a kind of hydraulic atomized nozzle, makes nozzle be difficult for stopping up, and can improve nebulization efficiency and steel powder lumber recovery.
For solving the problems of the technologies described above, the utility model is realized by following technical measures: a kind of hydraulic atomized nozzle, comprise nozzle water inlet, base, upper ring body, lower ring body and the nozzle circumferential weld that constitutes by upper ring body and lower ring body, on the nozzle boss of described lower ring body inner chamber middle part hole for water spraying is arranged.Water under high pressure makes the interior gas flow of nozzle more reasonable by forming a circle water column behind the hole for water spraying, and nozzle is difficult for stopping up, and can also play simultaneously to the powder cooling, protects powder, reduces the effect of steel powder oxygen content.
Described hole for water spraying is evenly distributed on the nozzle boss of lower ring body inner chamber middle part.Owing to the hole for water spraying distribution is very even, water under high pressure makes the interior gas flow of nozzle more stable by forming the uniform water column of a circle behind the hole for water spraying, and it is also more even to lower the temperature to steel powder, has improved the quality of steel powder.
The beneficial effects of the utility model are: owing on average have hole for water spraying on the nozzle boss of the lower ring body inner chamber middle part of hydraulic atomized nozzle, make water under high pressure form the uniform water column of a circle by hole for water spraying, make the interior gas flow of nozzle more reasonable, nozzle is difficult for stopping up, the quality of steel powder is more stable, improved the efficient and the success rate of atomizing, production can be carried out continuously.Water column is lowered the temperature to powder, and the protection powder reduces the effect of steel powder oxygen content.Through the experiment contrast, effect is very obvious, and benefit is very considerable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a generalized section of the present utility model;
Fig. 2 is the front section view of lower ring body among Fig. 1;
Fig. 3 is the elevational schematic view of lower ring body among Fig. 1.
1 for sitting at the end among the figure, and 2 is upper ring body, and 3 is lower ring body, and 4 is the nozzle circumferential weld, and 5 is hole for water spraying, and 6 is the nozzle water inlet, and 7 is steel ladle.
The specific embodiment
According to Fig. 1, Fig. 2 and shown in Figure 3, hydraulic atomized nozzle comprises nozzle water inlet (6), base (1), upper ring body (2), lower ring body (3) and nozzle circumferential weld (4), on the nozzle boss of described lower ring body (3) inner chamber middle part hole for water spraying (5) is arranged.Hole for water spraying (5) is evenly distributed on the nozzle boss of lower ring body (3) inner chamber middle part.Water under high pressure through pressurization enters from nozzle water inlet (6), and ejection is gathered together in the middle part from nozzle circumferential weld (4), forms the high pressure cascade of " inverted cone " type, is called " focusing ", and the summit of circular cone is called " focus point ".The interior molten steel of top steel ladle (7) forms molten steel stream, with the central lines of " inverted cone " type high pressure cascade, water under high pressure with the molten steel instantaneous trip, disperse, be cracked into small drop, fall into the pond of bottom, cooling becomes small iron and steel particle rapidly; Ejection from the hole for water spraying (5) of water under high pressure from the nozzle boss of lower ring body (3) inner chamber middle part that nozzle water inlet (6) enters simultaneously, form the uniform water column of a circle, strengthened the stability of air-flow in the nozzle,, can improve the oxygen content of powder again to the steel powder cooling.The diameter of aperture and quantity are according to different hydraulic pressure, the water yield and molten steel diameter, flow, and is definite by calculating.
Claims (2)
1, a kind of hydraulic atomized nozzle comprises nozzle water inlet, base, upper ring body, lower ring body and by the nozzle circumferential weld that upper ring body and lower ring body constitute, it is characterized in that: on the nozzle boss of described lower ring body inner chamber middle part hole for water spraying is arranged.
2, hydraulic atomized nozzle according to claim 1 is characterized in that: described hole for water spraying is evenly distributed on the nozzle boss of lower ring body inner chamber middle part.
