Description
Technical field
the utility model belongs to the desulfurizing iron apparatus field, relates in particular to a kind of desulfurizing iron/dephosphorization rotary spray gun.
Background technology
injection metallurgy typically refers to the fixed blowing process of widespread use in industry: spray gun is from furnace bottom, and furnace wall and furnace roof all remain static when jet in the molten bath.When spray gun when furnace bottom is upwards jetted, fixed blowing process is unique method, promptly spray gun need be fixed in the flame retardant coating of furnace bottom.When spray gun inserts winding-up from the furnace wall, generally also remain static.
Rifle core in
spray gun generally all is to adopt the plain carbon stool material, in order to guarantee the rigidity of rifle core, generally is furnished with many stiffening web pipes all around what the rifle core was responsible for, and all is the above weldless steel tubes of thick 5mm; The tectal material of refractory materials generally is that steel fiber strengthens the mullite-corundum mould material.In actual production,, restricted the raising in spray gun work-ing life because peeling off, ftractureing of rifle body refractory materials causes breakages such as rifle body crackle burns, fracture, bending.
existing hot metal pretreatment spray gun spray gun all adopts the static spray gun of single passage column type; It is big that this type of spray gun exists blowing media splash intensity; Blowing media and molten iron mixed effect are poor, in addition, owing to adopt the single hole structure; Very inconvenience when carrying out desulfurization and dephosphorization multiple working, its desulfurization/dephosphorization efficient obviously reduces.
The utility model content
the utility model is intended to overcome the weak point of prior art and a kind of mixing effect that mixes that improves molten iron and blowing media is provided; Change carrier gas stream come-up track, the desulfurizing iron/dephosphorization rotary spray gun that improves desulfurization and dephosphorization efficient and splash intensity is reduced.
For achieving the above object, the utility model is to realize like this
.
a kind of desulfurizing iron/dephosphorization rotary spray gun, it comprises flange, desulfurization jet pipe, dephosphorization jet pipe, is fixedly arranged on skeleton and refractory masses on desulfurization jet pipe and the dephosphorization jet pipe; One end and the flange of said desulfurization jet pipe and dephosphorization jet pipe are fixedly connected; Said desulfurization jet pipe and dephosphorization jet pipe place within the refractory masses; Said desulfurization jet pipe and dephosphorization jet pipe are flexure type.
as a kind of preferred version, the utility model is fixed with vaporizing chamber at the port of said desulfurization jet pipe and dephosphorization jet pipe.
as another kind of preferred version, the utility model is provided with rotating mechanism on said flange.
further, the utility model is provided with belt stress adjustment muscle at said refractory masses internal fixing.
the utility model can improve the mixing effect that mixes of molten iron and blowing media, changes carrier gas stream come-up track, improves desulfurization and dephosphorization efficient and also makes the reduction of splash intensity.
the utility model has carried out industrial test in the 65t ladle of desulfurization station, data show, can desulfurization and dephosphorization rate be improved 20%～30%, reduce metal splash loss, and cooling reduces 50%.The utility model has improved the mixing of molten iron and blowing media and has stirred, and has changed the track of carrier gas stream come-up, and bubble diminishes, and ascent rate is slack-off, and blowing media and molten iron mix better, has improved the desulfurization/dephosphorization rate and splash intensity is reduced.
Description of drawings
are described further the utility model below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the utility model one-piece construction synoptic diagram.
Among
figure: 1, flange; 201, desulfurization jet pipe; 202 dephosphorization jet pipes; 3, skeleton; 4, refractory masses; 6, belt stress adjustment muscle; 7, vaporizing chamber; 8, rotating mechanism.
Embodiment
are as shown in the figure, desulfurizing iron/dephosphorization rotary spray gun, and it comprises flange 1, desulfurization jet pipe 201, dephosphorization jet pipe 202, is fixedly arranged on skeleton 3 and refractory masses 4 on desulfurization jet pipe 201 and the dephosphorization jet pipe 202; One end and the flange 1 of said desulfurization jet pipe 201 and dephosphorization jet pipe 202 are fixedly connected; Said desulfurization jet pipe 201 and dephosphorization jet pipe 202 place within the refractory masses 4; Said desulfurization jet pipe 201 and dephosphorization jet pipe 202 are flexure type.
the utility model is fixed with vaporizing chamber 7 at the port of said desulfurization jet pipe 201 and dephosphorization jet pipe 202.The utility model is provided with rotating mechanism 8 on said flange 1.
are avoided the refractory materials cracking, are come off for improving the intravital stress distribution of rifle, and the utility model is provided with belt stress adjustment muscle 6 at said refractory masses 4 internal fixing.
the utility model is provided with rotating mechanism 8 on said flange 1.When carrying out desulfuration operations,, can rotating mechanism 8 be connected with related work mechanism when the rotation of needs rifle body.Like this, in the jet pipe blowing media, the rifle body also plays the mixing stirring action to molten iron and blowing media.
Insert from furnace roof at spray gun
, when spray gun and furnace roof are gapped, just can realize the swing or the rotation of spray gun.
The ladle of
desulfurizing iron and dephosphorization and torpedo car all are upper opening formula containers, and furnace roof inserts spray gun has the swing space, and dynamically the desulfurization of spray gun and dephosphorization are used has had possibility.In identical water model test, compare with fixing spray gun, the contriver finds that rotary spray gun diminishes bubble, and ascent rate is slack-off, and ascent rate is slack-off to diminish with bubble, and blistered intensity is relevant with the track that floats.
The above is merely the preferred embodiment of the utility model
, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
