Abstract
The invention belongs to the field of molten iron desulphurization equipment and particularly relates to a single-nozzle magnesium-based molten iron desulphurization spray gun. The spray gun comprises a gun body and is characterized in that the gun body comprises a protective pipe (4), a fireproof material layer (7), a framework (6), a central spray pipe (1), a distributor (5), a first side spray pipe (2) and a second side spray pipe (3), wherein the central spray pipe (1), the first side spray pipe (2) and the second side spray pipe (3) are sleeved inside the protective pipe (4); a desulfurizer outlet of the distributor (5) is communicated with desulfurizer inlets of the central spray pipe (1), the first side spray pipe (2) and the second side spray pipe (3); the fireproof material layer (7) is located outside the protective pipe (4); and the framework (6) is placed in the fireproof material layer (7) and is fixedly connected with the protective pipe (4). The single-nozzle magnesium-based molten iron desulphurization spray gun disclosed by the invention is high in desulphurization efficiency, air bubbles are distributed uniformly in a whole liquid phase, and the consumption of magnesium is low.
Description
Technical field
The invention belongs to the desulfurizing iron apparatus field, relate in particular to a kind of single jet magnesia mixture molten iron desulfuring spray gun.
Background technology
Development is widely used external desulfurization of hot metal blowing desulfurization technology so far from the 1950's.This technology can adapt to various sweetening agent preferably, gives full play to the sweetening power of sweetening agent, reaches good sweetening effectiveness.At present still to exist structure single for molten iron magnesium desulphurization spray gun, the skewness of bubble in liquid phase integral body, the problem such as desulfuration efficiency is low, and the magnesium consumption is large.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art part and provides a kind of desulfuration efficiency high, bubble being evenly distributed in liquid phase integral body, the single jet magnesia mixture molten iron desulfuring spray gun that the magnesium consumption is little.
For solving the problems of the technologies described above, the present invention realizes like this.
Single jet magnesia mixture molten iron desulfuring spray gun, it comprises gun body; Described gun body comprises pillar, refractory masses, skeleton, core jet pipe, divider, the first lateral jet pipe and the second lateral jet pipe; Described core jet pipe, the first lateral jet pipe and the second lateral jet pipe are set in the pillar; The sweetening agent outlet of described divider communicates with core jet pipe, the first lateral jet pipe and the second lateral jet pipe sweetening agent entrance; Described refractory masses is positioned at the outside of pillar; Described skeleton is inserted in the refractory masses and with pillar and is fixedly connected.
As a kind of preferred version, the vertical drift angle a of the first nozzle of the first lateral jet pipe of the present invention is 15～30o; The vertical drift angle b of the second nozzle of the second lateral jet pipe is 15～30o.
As another kind of preferred version, the bottom of gun body of the present invention can be semisphere.
Further, the difference of altitude h of the first nozzle of the present invention and the second nozzle is 10～50cm.
Desulfuration efficiency of the present invention is high, bubble being evenly distributed in liquid phase integral body, and the magnesium consumption is little.Because adopt the structure design of core jet pipe, divider, the first lateral jet pipe and the second lateral jet pipe, the present invention has obviously improved the desulfuration efficiency of spray gun.In addition, because there are difference of altitude in the first nozzle and the second nozzle, this combination that makes melt and sweetening agent changes into a kind of three-dimensional combination by point-face, and commercial test results shows: use novel spray gun can reduce magnesium consumption 28.5%, significantly improve utilization ratio and the desulfuration efficiency of sweetening agent.Splash was less when spray gun used, and the life-span is suitable with former spray gun.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is one-piece construction synoptic diagram of the present invention.
Among the figure: 1, core jet pipe; 2, the first lateral jet pipe; 3, the second lateral jet pipe; 4, pillar; 5, divider; 6, skeleton; 7, refractory masses; 201, the first nozzle; 301, the second nozzle.
Embodiment
As shown in the figure, single jet magnesia mixture molten iron desulfuring spray gun, it comprises gun body; Described gun body comprises pillar 4, refractory masses 7, skeleton 6, core jet pipe 1, divider 5, the first lateral jet pipe 2 and the second lateral jet pipe 3; Described core jet pipe 1, the first lateral jet pipe 2 and the second lateral jet pipe 3 are set in the pillar 4; The sweetening agent outlet of described divider 5 communicates with core jet pipe 1, the first lateral jet pipe 2 and the second lateral jet pipe 3 sweetening agent entrances; Described refractory masses 7 is positioned at the outside of pillar 4; Described skeleton 6 is inserted in the refractory masses 7 and with pillar 4 and is fixedly connected.
The vertical drift angle a of the first nozzle 201 of the first lateral jet pipe 2 of the present invention is 18o; The vertical drift angle b of the second nozzle 301 of the second lateral jet pipe 3 is 18o.
The impact of impacting for reducing melt, the bottom of gun body of the present invention is semisphere.
The difference of altitude h of the first nozzle 201 of the present invention and the second nozzle 301 is 35cm.
During use, under the effect of carrier gas, sweetening agent enters respectively core jet pipe 1, the first lateral jet pipe 2 and the second lateral jet pipe 3 through the outlet of the sweetening agent of divider 5, enters respectively from the nozzle of core jet pipe 1 and the first nozzle 201 and the second nozzle 301 and carries out desulfuration operations the melt.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
