Description
Technical field
The utility model relates to a kind of shower nozzle of aluminium alloy smelting degasification.
Background technology
In aluminium alloy smelting process, because melt absorbs aqueous vapor from air, or the moisture of the raw material of non-drying band itself, water vapour a large amount of under high temperature is decomposed into hydrogen [H] or the hydrogen of (3H2O+2AL=AL2O3+6 [H]) atomic condition by active aluminium, hydrogen is mainly dissolved in aluminium solution with atomic condition, is also adsorbed on impurity with molecularity.Aluminium alloy melt will be cast after refining, and the aluminium alloy solution containing more hydrogen produces a lot of casting flaw in castingprocesses, mainly exists in foundry goods with pore, pinprick and slag inclusion form.Therefore aluminium alloy smelting needs degasification, usually use nitrogen degasification in production, namely directly insert nitrogen blowing in melt and uniform stirring with the steel pipe of DN20, hydrogen is separated out by melt with nitrogen bubble, the defect of this method is that nitrogen-blow is concentrated, and easily causes melt liquid level to roll and slag making air-breathing.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of shower nozzle of aluminium alloy smelting degasification, this shower nozzle is welded on DN20 steel pipe, in aluminium alloy smelting degassing procedure, can ensure that nitrogen pressure is suitable, make nitrogen injection area greatly and evenly, bubble disperse in aluminium liquid is floated and separates out, the melt rolling that reduction nitrogen is concentrated winding-up and caused, makes nitrogen form more small bubbles disperse in the melt, takes hydrogen out of as much as possible when small bubbles separate out melt gradually.
The utility model is for solving the problems of the technologies described above adopted technical scheme as described below:
A kind of aluminium alloy smelting degasification shower nozzle, described shower nozzle is one section of DN50 steel pipe, evenly arranges 70 ~ 90 through holes in described steel tube surface, and the diameter of described through hole is 2mm,
Weld a circular plug in steel pipe one end and arrange 5 ~ 7 through holes on this circular plug, the diameter of described through hole is 2mm,
Weld a circular plug at the steel pipe the other end and on circular plug, arrange through hole 1 through hole, the diameter of described through hole is 20mm.
Further, the thickness of described circular plug is 5mm.
Further again, the length of described DN50 steel pipe is 300mm.
The beneficial effects of the utility model are: degasification shower nozzle of the present utility model is welded on DN20 steel pipe, in aluminium alloy smelting degassing procedure, the melt rolling that reduction nitrogen is concentrated winding-up and caused, increase nitrogen injection area simultaneously, make nitrogen form more small bubbles disperse in the melt, take hydrogen out of as much as possible when small bubbles separate out melt gradually.The utility model structure is simple, reasonable in design, ensures that nitrogen pressure is suitable, makes nitrogen injection area greatly and evenly, and bubble disperse in aluminium liquid is floated and separates out.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described.
A kind of aluminium alloy smelting degasification shower nozzle, as shown in Figure 1, described shower nozzle is one section of DN50 steel pipe 1, evenly arranges 70 ~ 90 through holes 2 in described steel tube surface, and the diameter of described through hole is 2mm.
As shown in Figure 2, weld a circular plug 3 and arrange 5 ~ 7 through holes in steel pipe one end on this circular plug, the diameter of described through hole is 2mm, and the thickness of described circular plug is 5mm.
As shown in Figure 3, weld a circular plug 3 at the steel pipe the other end and on circular plug, arrange through hole 1 through hole, the diameter of described through hole is 20mm, and the thickness of described circular plug is 5mm.
The length of DN50 steel pipe described in the utility model is 300mm.
In one embodiment, the technical solution of the utility model is: intercept the DN50 steel pipe that 300mm is long, with ∮ 2mm drill bit the uniform boring of steel tube surface 70 ~ 90 through holes (as shown in Figure 1), the thick circular plug of 5mm is welded and uniform brill ∮ 2mm through hole 5 ~ 7 (as shown in Figure 2) in steel pipe one end, the steel pipe the other end welds the thick circular plug of 5mm and cloth bores ∮ 20mm through hole 1 (as shown in Figure 3), DN20 steel pipe will be welded in the steel pipe one end with a through hole, it is exactly degasification shower nozzle (as shown in Figure 4) after two ends plug has welded, for aluminium alloy smelting degasification after this shower nozzle and DN20 steel-pipe welding, nitrogen must be kept to ventilate all the time before noting each degasification insertion melt with after extracting, otherwise aluminium alloy solution solidifies and may block 2mm pore.
The beneficial effects of the utility model are: degasification shower nozzle of the present utility model is welded on DN20 steel pipe, in aluminium alloy smelting degassing procedure, the melt rolling that reduction nitrogen is concentrated winding-up and caused, increase nitrogen injection area simultaneously, make nitrogen form more small bubbles disperse in the melt, take hydrogen out of as much as possible when small bubbles separate out melt gradually.The utility model structure is simple, reasonable in design, ensures that nitrogen pressure is suitable, makes nitrogen injection area greatly and evenly, and bubble disperse in aluminium liquid is floated and separates out.
It should be noted that; above-mentioned specific embodiment is only exemplary; under above-mentioned instruction of the present utility model, those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improve or distortion all drops in protection domain of the present utility model.It will be understood by those skilled in the art that specific descriptions are above to explain the purpose of this utility model, not for limiting the utility model.Protection domain of the present utility model is by claim and equivalents thereof.
