Abstract
The utility model discloses an argon blowing and long nozzle, which comprises a long nozzle bowl body, a steel casing, and an argon blowing mouth which is on the outer wall of the steel casing. The argon blowing and long nozzle is characterized in that the periphery of the long nozzle bowl body which is aligned with the argon blowing mouth is provided with a vent groove and 4 to 8 vent holes, and the vent holes communicate with the vent groove and the inner wall of the long nozzle bowl body respectively. The argon blowing and long nozzle has advantages of being simple in structure, being ingenious in design, being capable of avoiding the phenomena of high pressure air in air inlet end and staying away from low pressure air in air inlet end, being good in air-sealing effect, and being able to form stable and uniform air curtain between the long nozzle bowl body and the ladle nozzle so that oxygen inhalation and nitrogen inhalation of the molten steel are avoided in the process of pouring.
Description
Technical field
The utility model relates to the refractory for continuous casting field, relates in particular to a kind of argon blowing long nozzle.
Background technology
Existing argon blowing long nozzle Argon mode has two kinds, and the A kind is by the groove Argon of the Argon mouth on the iron-clad to the long water gap bowl part inwall, forming air curtain between the mouth of a river and long water gap bowl part under the large bag, reaches the purpose of sealing gland; The B kind be colored shape air flue by the Argon mouth on the iron-clad, long nozzle bottom surface to the long water gap bowl part Argon, forming air curtain between the mouth of a river and long water gap bowl part under the large bag, reach the purpose of sealing gland.These two kinds of Argon modes all exist nearly inlet end gas pressure large, and are little away from the inlet end gas pressure, cause the sealing gland effect undesirable, can not prevent effectively that the oxygen uptake of molten steel from inhaling nitrogen.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, to provide a kind of sealing gland effective argon blowing long nozzle.
The utility model is achieved through the following technical solutions:
A kind of argon blowing long nozzle, include long water gap bowl part body, iron-clad and at the Argon mouth of iron-clad outer wall, it is characterized in that: the position of aiming at the Argon mouth in described long water gap bowl part body periphery is provided with air channel and 4 to 8 passages, described passage respectively with described air channel and long water gap bowl part inner body wall UNICOM, at the air curtain that forms stable and uniform under long water gap bowl part inner body wall and the large bag between the mouth of a river.
Operation principle of the present utility model is: argon gas enters from the Argon mouth, at the air curtain that forms stable and uniform under long water gap bowl part inner body wall and the large bag between the mouth of a river, reaches the purpose of sealing gland by air channel and passage.
The utility model has the advantages that: the utility model is simple in structure, design ingenious, avoided the inlet end gas pressure large, away from the little phenomenon of inlet end gas pressure, sealing gland is effective, forming stable even air curtain between the mouth of a river under long water gap bowl part body and the large bag, avoiding the oxygen uptake of molten steel in casting cycle and inhaled nitrogen.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of argon blowing long nozzle, include long water gap bowl part body 1, iron-clad 2 and at the Argon mouth 3 of iron-clad 2 outer walls, it is characterized in that: the position of aiming at Argon mouth 3 in described long water gap bowl part body 1 periphery is provided with air channel 4 and 4 to 8 passages 5, described passage 5 respectively with described air channel 4 and long water gap bowl part body 1 inwall UNICOM, at the air curtain that forms stable and uniform under long water gap bowl part body 1 inwall and the large bag between the mouth of a river 6.
Claims (1)
