Abstract
The utility model relates to an oxygen lance with clustered beam which comprises an oxygen lance body and a spray head, wherein an inner cavity of the oxygen lance body is sequentially sheathed with a main oxygen pipe, a gas pipeline, an auxiliary oxygen pipe and a corresponding joint from inside to outside; the spray head is connected at the front end of the oxygen lance body and corresponds to the main oxygen pipe, the gas pipeline and the auxiliary oxygen pipe; a main oxygen nozzle, a plurality of gas nozzles and an auxiliary oxygen nozzle are arranged from the exterior of the center along the axial direction of the spray head; the gas nozzles have the diameters within the range of 3-10mm; and more than 15 gas nozzles are available. Under the condition of not influencing the original smelting effect of the oxygen lance with clustered beam, the diameters of the gas nozzles are reduced, and the number of the gas nozzles is increased, so that the gas eject efficiency is increased, the dosage of liquefied natural gas (LNG) is reduced, and an LNG accompanying layer is more even.
Description
Technical field
The utility model relates to smelting uses oxygen rifle, particularly a kind of coherent oxygen lance.
Background technology
The principle of coherent oxygen lance is to increase outer layer ring around following stream around traditional oxygen rifle, makes center supersonic jet expansion and decay less, and supersonic jet is longer.Improve oxygen jet to penetration depth and the stirring intensity in molten bath, because the jet speed decay delays, can improve the blowing rifle position of oxygen rifle, and not affect jet to the impact depth of molten steel simultaneously, prolonged the work-ing life of oxygen lance blow head.
The coherent oxygen lance of using on more domestic furnace equipments adopts two outer layers around following substantially, and what one deck was used is oxygen, and that one deck is used is combustion gas LNG.Because the consumption of combustion gas LNG is very large, thus certain cost brought to steel-making, even some producers reduce the flow of combustion gas LNG for Cost reduction, so just lost the outer layer protection effect, have brought to steel-making to seriously influence.
Summary of the invention
The purpose of this utility model is to design a kind of coherent oxygen lance, is not affecting under the original metallurgical effect of coherent oxygen lance, reduces the consumption of combustion gas LNG and makes combustion gas LNG follow layer more even.
For achieving the above object, the technical solution of the utility model is:
A kind of coherent oxygen lance comprises, rifle body, its inner chamber be successively sheathed main oxygen pipe, gas pipeline, secondary oxygen hose and corresponding joint from inside to outside; Shower nozzle is connected in rifle body front end, corresponding described main oxygen pipe, gas pipeline, secondary oxygen hose, and nozzle axis is to offer successively main oxygen spout, some combustion gas spouts and secondary oxygen spout outside the center; It is characterized in that, the diameter of described combustion gas spout is 3 ~ 10mm, and spout quantity is more than 15.
Further, the spout quantity of described combustion gas spout is 18 ~ 38.
The spout of described combustion gas spout tilts to main oxygen spout direction, and combustion gas spout axis becomes 0 ° ~ 20 ° with level.
The beneficial effects of the utility model:
The utility model is guaranteeing under the original metallurgical effect of oxygen rifle, by reducing the combustion gas nozzle diameter, increases combustion gas spout quantity, has improved fuel gas injection efficient, effectively reduces the usage quantity of combustion gas LNG; And combustion gas spout and corresponding combustion gas LNG spray more even, to the protection better effects if of main oxygen.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the side-view of Fig. 1.
Embodiment
Referring to Fig. 1, Fig. 2, a kind of coherent oxygen lance of the present utility model comprises, rifle body 1, its inner chamber be successively sheathed main oxygen pipe 10, gas pipeline 20, secondary oxygen hose 30 and corresponding joint from inside to outside; Shower nozzle 2, be connected in rifle body 1 front end, corresponding described main oxygen pipe 10, gas pipeline 20, secondary oxygen hose 30, shower nozzle 2 is axially offered main oxygen spout 21, some combustion gas spouts 22 and secondary oxygen spout 23 successively outside the center, namely form two circles around main oxygen spout 21 and follow layer, i.e. combustion gas spout 22 and secondary oxygen spout 23; The diameter of described combustion gas spout 22 is 3 ~ 10mm, and spout quantity is more than 15.
In the present embodiment, the spout quantity of described combustion gas spout 22 is 18 ~ 38.The spout of described combustion gas spout 22 tilts to main oxygen spout 21 directions, combustion gas spout 22 axis α in an angle with the horizontal, α=0 ° ~ 20 °.
The utility model increases combustion gas spout quantity by reducing the combustion gas nozzle diameter, has improved fuel gas injection efficient, effectively reduces the usage quantity of combustion gas LNG; And combustion gas spout and corresponding combustion gas LNG spray more even, to the protection better effects if of main oxygen.
