The granulated magnesium molten iron desulphurization spray gun comprises a carrier gas spray pipe (4), a refractory material layer (7), a skeleton (6) and a central spray pipe (1), wherein a vaporizing chamber (3) is arranged at the bottom of the central spray pipe (1); the central spray pipe (1) is sheathed in the carrier gas spray pipe (4); the lower port of the central spray pipe (1) is communicated with the vaporizing chamber (3); the refractory material layer (7) is arranged outside the carrier gas spray pipe (4); the skeleton (6) is arranged inside the refractory material layer (7) and is fixedly connected with the carrier gas spray pipe (4); a first carrier gas exhaust nozzle (8) and a second carrier gas exhaust nozzle (9) are fixedly arranged at different sections in the longitudinal direction of the carrier gas spray pipe (4); and distance h between the lower ends of the first carrier gas exhaust nozzle (8) and the second carrier gas exhaust nozzle (9) is 20-45cm. The granulated magnesium molten iron desulphurization spray gun has high desulphurization efficiency, air bubbles are uniformly distributed in a liquid phase whole, and magnesium consumption is low.
Description
Technical field
the utility model belongs to the desulfurizing iron apparatus field, relates in particular to a kind of granule magnesium molten iron desulfuring spray gun.
Background technology
from the 1950's, development is widely used external desulfurization of hot metal blowing desulfurization technology so far.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 utility model is intended to overcome the deficiencies in the prior art part and provides a kind of desulfuration efficiency high, and bubble being evenly distributed in liquid phase integral body, can effectively reduce the melt splash, a kind of granule magnesium molten iron desulfuring spray gun that the magnesium consumption is little.
for solving the problems of the technologies described above, the utility model is to realize like this.
a kind of granule magnesium molten iron desulfuring spray gun, it comprises gun body; Described gun body comprises carrier gas jet pipe, refractory masses, skeleton and core jet pipe; Bottom at described core jet pipe is provided with vaporizing chamber; Described core jet pipe is set in the carrier gas jet pipe; The lower port of described core jet pipe communicates with vaporizing chamber; Described refractory masses is positioned at the outside of carrier gas jet pipe; Described skeleton is inserted in refractory masses and is fixedly connected with the carrier gas jet pipe; Vertical different sections at described carrier gas jet pipe are fixed with the first carrier gas jet pipe and the second carrier gas jet pipe; The lower end distance h of described the first carrier gas jet pipe and the second carrier gas jet pipe=20～45cm.
as a kind of preferred version, vertical drift angle a of the utility model the first carrier gas jet pipe and vertical drift angle b of the second carrier gas jet pipe meet: a-b=8～11 o.
the utility model desulfuration efficiency is high, bubble being evenly distributed in liquid phase integral body, and the magnesium consumption is little.Due to the structure design that adopts core jet pipe carrier gas jet pipe, the first carrier gas jet pipe and the second carrier gas jet pipe, the utility model has obviously improved the desulfuration efficiency of spray gun.In addition, because there are difference of altitude in the first carrier gas jet pipe and the second carrier gas jet pipe, and vertical drift angle b of the vertical drift angle a of the first carrier gas jet pipe and the second carrier gas jet pipe meets: a-b=8～11 o, this makes carrier gas all exert an influence to the melt in different depths zone, and the steam bubble of simultaneously vaporizing chamber being taken out of plays good restraining effect.
commercial test results shows: use novel spray gun can reduce magnesium consumption 30.1%, significantly improve utilization ratio and the desulfuration efficiency of sweetening agent.When spray gun uses, splash is less, and the life-span is suitable with former spray gun.
The accompanying drawing explanation
below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
fig. 1 is the utility model one-piece construction schematic diagram.
in figure: 1, core jet pipe; 3, vaporizing chamber; 4, carrier gas jet pipe; 6, skeleton; 7, refractory masses; 8, the first carrier gas jet pipe; 9, the second carrier gas jet pipe.
Embodiment
as shown in the figure, a kind of granule magnesium molten iron desulfuring spray gun, it comprises gun body; Described gun body comprises carrier gas jet pipe 4, refractory masses 7, skeleton 6 and core jet pipe 1; Be provided with vaporizing chamber 3 in the bottom of described core jet pipe 1; Described core jet pipe 1 is set in carrier gas jet pipe 4; The lower port of described core jet pipe 1 communicates with vaporizing chamber 3; Described refractory masses 7 is positioned at the outside of carrier gas jet pipe 4; Described skeleton 6 is inserted in refractory masses 7 and is fixedly connected with carrier gas jet pipe 4; Vertical different sections at described carrier gas jet pipe 4 are fixed with the first carrier gas jet pipe 8 and the second carrier gas jet pipe 9; Lower end distance h=the 31cm of described the first carrier gas jet pipe 8 and the second carrier gas jet pipe 9.
as a kind of preferred version, vertical drift angle a of the utility model the first carrier gas jet pipe 8 and vertical drift angle b of the second carrier gas jet pipe 9 meet: a-b=9 o.The first carrier gas jet pipe 8 and the second carrier gas jet pipe 9 can adopt respectively one or more.
during use, under the effect of carrier gas, desulfurizing and demagging agent carries out in melt carrying out desulfuration operations through core jet pipe 1 and vaporizing chamber 3.Meanwhile, carrier gas is injected in the different zones of melt through carrier gas jet pipe 9, the first carrier gas jet pipe 8 and the second carrier gas jet pipe 9, this makes carrier gas all exert an influence to the melt in different depths zone, and the steam bubble of simultaneously vaporizing chamber being taken out of plays good restraining effect.
the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
