Abstract
The utility model belongs to the field of molten iron desulfuration equipment, and particularly relates to an L-shaped molten iron predesulfuration lance, which comprises a flange (1), a jet tube (2), a skeleton (3) fixed on the jet tube (2) and a refractory layer (4); one end of the jet tube (2) is fixedly connected with the flange (1); the jet tube (2) is arranged in the refractory layer (4); the jet tube (2) is L-shaped; a refractory sleeve (5) is fixed on the other end of the jet tube (2); a protective tube (6) is fixedly sleeved on the jet tube (2); a flared gasification chamber (7) is fixed on the bottom of the jet tube (2); and a rotating mechanism (8) is arranged on the flange (1). The L-shaped molten iron predesulfuration lance can enhance the effect of mixing molten iron and desulfurizer, change the floating track of carrier gas flow, increase the desulfuration rate and decrease the splashing strength.
Description
Technical field
the utility model belongs to the desulfurizing iron apparatus field, relates in particular to a kind of L sections water pretreatment desulphurization 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.
Characteristics such as
existing desulfurizing spray gun for pretreating molten iron all adopts the static spray gun of column type, and it is big that this type of spray gun exists sweetening agent splash intensity, and sweetening agent and molten iron mixed effect are poor, and desulfuration efficiency is low.
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 sweetening agent is provided; Change carrier gas stream come-up track, the L sections water pretreatment desulphurization spray gun that improves desulfurization degree and splash intensity is reduced.
for solving the problems of the technologies described above, the utility model is achieved in that L sections water pretreatment desulphurization spray gun, and it comprises flange, jet pipe, is fixedly arranged on skeleton and refractory masses on the jet pipe; One end and the flange of said jet pipe are fixedly connected; Said jet pipe places within the refractory masses; Said jet pipe is the L type.
as a kind of preferred version, the utility model is fixed with refractory sleeve at the other end of said jet pipe.
as another kind of preferred version, the utility model is with protecting tube at said jet pipe external fixation.
further, the utility model is fixed with the hydraucone vaporizing chamber in the bottom of said jet pipe.
further, the utility model can be provided with rotating mechanism on said flange.
the utility model has carried out industrial test in the 65t ladle of desulfurization station, data show, can desulfurization degree be improved 20%～30%, reduces metal splash loss, and cooling reduces 50%.The utility model has improved the mixing of molten iron and sweetening agent and has stirred, and has changed the track of carrier gas stream come-up, and bubble diminishes, and ascent rate is slack-off, and sweetening agent and molten iron mix better, has improved desulfurization degree 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 a kind of embodiment structural representation of the utility model.
Fig. 2 is the another kind of embodiment structural representation of the utility model.
Among
figure: 1, flange; 2, jet pipe; 3, skeleton; 4, refractory masses; 5, refractory sleeve; 6, protecting tube; 7, hydraucone vaporizing chamber; 8, rotating mechanism.
Embodiment
are as shown in the figure, L sections water pretreatment desulphurization spray gun, and it comprises flange 1, jet pipe 2, is fixedly arranged on skeleton 3 and refractory masses 4 on the jet pipe 2; One end and the flange 1 of said jet pipe 2 are fixedly connected; Said jet pipe 2 places within the refractory masses 4; Said jet pipe 2 is the L type.
the utility model is fixed with refractory sleeve 5 at the other end of said jet pipe 2.
are protection jet pipe 2, and the utility model is with protecting tube 6 at said jet pipe 2 external fixation.
referring to Fig. 2, the utility model is fixed with hydraucone vaporizing chamber 7 in the bottom of said jet pipe 2.
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 jet pipe 2 blowing desulfurization agent, the rifle body also plays the mixing stirring action to molten iron and sweetening agent.
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 torpedo car all are upper opening formula containers, and furnace roof inserts spray gun has the swing space, and dynamically the Desulfurization Application of spray gun has had possibility.In identical water model test, compare with fixing spray gun, utility model people 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.
