Abstract
The utility model belongs to the field of molten iron desulphurization treatment devices, and particularly relates to a built-in elbow pipe desulphurization lance. The built-in elbow pipe desulphurization lance comprises a lance body (2), wherein the lance body (2) comprises a first pipeline (101), a second pipeline (102), a refractory material layer (4), a framework (3) and a plurality of ring-shaped ribs (5), wherein the framework (3) is arranged in the refractory material layer and fixedly and adaptively connected with the first pipeline (101) and the second pipeline (102); the ring-shaped ribs (5) are fixedly and adaptively connected with the first pipeline (101) and the second pipeline (102) via transverse ribs (6); an eccentric angle Alpha at the tail part of the first pipeline (101) is larger than or equal to 20 DEG and smaller than or equal to 35 DEG; the second pipeline (102) is a through type pipeline; the bottom (7) of a body of the lance body (2) is hemisphere-shaped; and eagle-claw-shaped frameworks (9) are fixedly arranged on the transverse ribs (6). The built-in elbow pipe desulphurization lance has the advantages that the goodness of fit of the refractory material and the framework of the lance body is high, the framework of the lance body has a low probability of mechanical deformation, and dead angles are not liable to be produced in the spray process.
Description
Technical field
the utility model belongs to desulfurizing iron treatment unit field, relates in particular to a kind of built-in bend pipe desulphurization spray gun.
Background technology
are present, in smelting industry, before the steel-making, generally all will carry out the desulfurization pre-treatment to molten iron, and the used major equipment of above-mentioned technology is exactly a desulphurization spray gun.Existing molten iron desulfuring spray gun is not owing to take into full account the physical difference of pipeline and refractory masses in skeleton and the design of rifle body, spray gun when colding and heat succeed each other the state use, phenomenon such as refractory masses is prone to cause cracking, come off.In addition, because refractory materials and rifle body skeleton is steady right not high, rifle body skeleton is eccentric; Make equipment when actual motion, exist refractory masses and lost efficacy the mechanical deformation of rifle body skeleton; Characteristics such as the rifle body life time is short; Once more, the nozzle of existing spray gun is typically provided to through type, and this set tends to cause the winding-up dead angle.Owing to there is above-mentioned shortcoming, cause successfully carrying out secondary desulfurization, especially in large-scale (being equal to or greater than 160t) hot metal ladle, its structural defective is more obvious.
The utility model content
the utility model is intended to overcome the weak point of prior art and provides a kind of simple in structure; Running cost is cheap; The steady right height of refractory materials and rifle body skeleton; Rifle body skeleton is difficult for producing mechanical deformation, and winding-up is difficult for producing dead angle, the built-in bend pipe desulphurization spray gun of rifle body long service life.
For achieving the above object, the utility model is to realize like this
.
built-in bend pipe desulphurization spray gun comprises gun body; Said gun body comprises first pipeline, second pipeline, refractory masses, skeleton and annular rib; Said skeleton places in the refractory masses and with first pipeline and second pipeline and fixedly connects; Said annular rib fixedly connects through horizontal bar and first pipeline and second pipeline; 20 °≤a of the said first pipeline afterbody eccentrical angle≤35 °; Said second pipeline adopts through type.
as a kind of preferred version, the body of the said gun body of the utility model bottom can be dome-type.
as another kind of preferred version, the utility model annular rib is several concentric annular ribs; On said horizontal bar, be fixed with claws of a hawk type skeleton.
the utility model is simple in structure, and running cost is cheap, and the steady right height of refractory materials and rifle body skeleton, rifle body skeleton are difficult for producing mechanical deformation, rifle body long service life.The utility model adopts the concentric annular rib structure of claws of a hawk type skeleton in addition, this thinking has been improved the stress distribution situation of rifle body and refractory masses, thereby has alleviated the generation of phenomenons such as spray gun surface refractory materials ftractures, comes off.In addition, the body bottom is the outside strained condition that the dome-type structure Design can be improved the rifle body, has improved the stability of rifle body.Adopt built-in bend pipe and through type piping design can improve winding-up efficient, eliminate the winding-up dead angle.
Description of drawings
are described further the utility model below in conjunction with accompanying drawing and embodiment.The protection domain of the utility model will not only be confined to the statement of following content.
Fig. 1 is the built-in bend pipe desulphurization spray gun of a utility model one-piece construction synoptic diagram.
Among
figure: 101, first pipeline; 102, second pipeline; 2, gun body; 3, skeleton; 4, refractory masses; 5, annular rib; 6, horizontal bar; 7, body bottom; 9, claws of a hawk type skeleton.
Embodiment
are as shown in the figure, and built-in bend pipe desulphurization spray gun comprises gun body 2; Said gun body 2 comprises first pipeline 101, second pipeline 102, refractory masses 4, skeleton 3 and annular rib 5; Said skeleton 3 places in the refractory masses and with first pipeline 101 and second pipeline 102 and fixedly connects; Said annular rib 5 fixedly connects through horizontal bar 6 and first pipeline 101 and second pipeline 102; 20 °≤a of said first pipeline, 101 afterbody eccentrical angles≤35 °; Said second pipeline 102 adopts through type.
The body bottom 7 of
said gun body 2 of the utility model is dome-type.The strained condition of gun body can effectively be improved in dome-type body bottom 7, makes because of bath movement causes vibration to be able to clear up.
for strengthening the stress distribution effect, the said annular rib 5 of the utility model is several concentric annular ribs.The phenomenon that this structure design can effectively solve the refractory masses longitudinal cracking, come off.
the utility model is fixed with claws of a hawk type skeleton 9 on said horizontal bar 6.
it is understandable that; More than about the specific descriptions of desulphurization spray gun, only in order to explanation the utility model and unrestricted the utility model, those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement the utility model; To reach identical technique effect, as long as satisfy the use needs, the adjustment that the above-mentioned means of any foundation are made is all within the protection domain of the utility model.
