Abstract
The invention belongs to iron melt desulfuration device field and especially relates to iron melt desulfuration spray gun, characterized as comprising duct (1),gun body (2), fire resistive material layer (4)outboard of gun body(2),skeleton(3)outboard of gun body and inside fire resistive material layer, the said duct(1)fixing within gun body, the said duct(1) exit assembling a fire resistive sleeve(5), said duct (1)exit being belling structure. The inventive device has a simple structure, high desulfuration agent utilization, low cost in operation, good desulfuration effect, can stably conduct granule magnesium into iron melt .
Description
Technical field
The invention belongs to desulfurizing iron treatment unit category, particularly a kind of molten iron desulfuring spray gun.
Background technology
All there are high, the shortcomings such as sorbent utilization is low, spray gun body heaviness, desulphurization cost height of material consumption in existing molten iron desulfuring spray gun.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.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple in structure, sorbent utilization is high, working cost is cheap, sweetening effectiveness is good molten iron desulfuring spray gun.
Technical solution of the present invention can realize according to following mode:
A kind of The magnesia spray gun of liquid iron in desulfuriaton process is characterized in, contains: pipeline, gun body, be positioned at the gun body outside refractory masses, be attached to the skeleton that gun body places refractory masses outward again; Described pipeline is assemblied in the gun body.
Exit end at described pipeline is furnished with refractory sleeve.The exit end of described pipeline is the hydraucone structure.
Described pipeline places in the gun body, and keeps certain distance with the inwall of gun body.
The internal diameter of described pipeline is equal to or greater than 10 times of magnesium granules diameter, and its length is not less than 420 times of internal diameter of the pipeline.
The raw material thing of refractory masses of the present invention contains following component (weight percentage):
Bauxitic clay 62～90%
Corundum 20～25%
Steel fiber 2～3%
Luminite cement 5～11%
The present invention is simple in structure, sorbent utilization is high, working cost is cheap, sweetening effectiveness is good, can be stably imports particle magnesium in the molten iron and obtains very high desulfurization index.

Fig. 2 is an another kind of frame mode exit end structural representation of the present invention;
Fig. 3 is actual motion state graph of the present invention.
Embodiment
The present invention contains: pipeline 1, gun body 2, be positioned at gun body 2 outsides refractory masses 4, be attached to the outer skeletons 3 that place refractory masses again of gun body 2; Described pipeline 1 can fixedly be assemblied in the gun body 2, and pipeline 1 also can be fitted in the gun body 2 by removably.Is furnished with refractory sleeve 5 at the exit end of described pipeline 1.The exit end of described pipeline 1 is the hydraucone structure.Described pipeline 1 places in the gun body 2, and keeps certain distance with the inwall of gun body 2.The internal diameter of described pipeline 1 is equal to or greater than 10 times of magnesium granules diameter, and its length is not less than 420 times of pipeline 1 internal diameter.
Pipeline 1 of the present invention is used to carry magnesia mixture, and skeleton 3 and gun body 2 all adopt steel material.Refractory sleeve 5 can prevent that the pipe of pipeline 1 from contacting with molten iron.The performance that the anti-molten iron of refractory sleeve material soaks into is fine, and very high anti-chilling and shock heating intensity is arranged, and this has stable geometrical shape with regard to the pipeline that has guaranteed spray gun exit when jetting magnesia mixture in molten iron.When heavy wear, can change a new refractory sleeve rapidly and needn't change the very expensive whole spray gun of price.The length of refractory sleeve 5 is 2～8 times of pipeline 1 internal diameter, if pipeline 1 just may contact with molten iron during less than 2 times, and the replacing refractory sleeve is had any problem during greater than 8 times, thereby all unreasonable.Described conveying magnesia mixture pipeline 1 places in the gun body 2 of steel construction and keeps certain distance with the inwall of the gun body 2 of steel construction, so can guarantee and carry the heat insulation of magnesia mixture pipeline 1, prevent to carry magnesia mixture pipeline 1 to be heated and prevent that magnesia mixture from adhering on conveying magnesia mixture pipeline 1.The exit end of described conveying magnesia mixture pipeline 1 can be the hydraucone shape, and the internal diameter of described conveying magnesia mixture pipeline 1 is equal to or greater than 10 times of magnesium granules diameter, and its length is not less than 420 times that carry magnesia mixture pipeline 1 internal diameter.
Earlier confess gas by the flexible pipe of desulphurization spray gun from spray magnesium jar 6 to the hot metal ladle 7 of the molten iron of packing in during this device busy, flow is per hour pressed 15～30 cubic metres to every square metre of bath surface air feed.After then desulphurization spray gun being inserted the degree of depth that reaches necessary in the molten iron, in spray gun, confess magnesia mixture and be imported in the molten iron through leading magnesium pipeline 8, provide magnesia inventory and control by 1-3kg/ ton iron by spray magnesium can system.9 is molten iron.
1) the raw material thing of above-mentioned refractory masses contains following ingredients (weight percent content):
Bauxitic clay 64%
Corundum 20%
Luminite cement 8%
Steel fiber 2%
2) the raw material thing of above-mentioned refractory masses contains following ingredients (weight percent content):
