Abstract
The utility model discloses a steel ladle long nozzle oxygen burning device which comprises an oxygen blowing pipe. A blowing-sweeping end of the oxygen blowing pipe is connected with a hemispherical nozzle. The bottom face of the nozzle is a plane. Spraying holes are evenly distributed in the bottom face of the nozzle at intervals in a central-symmetry mode. The diameters of the spraying holes are 1.5 mm. The outer diameter of the bottom face of the nozzle is smaller than the outer diameter of the wrist portion of a steel ladle long nozzle. The steel ladle long nozzle oxygen burning device is simple in structure, the oxygen blowing-sweeping area can be increased, intensity is lowered, blow-sweeping time is shortened, blow-sweeping effect is improved, manpower is saved, material resources are saved, a worker working environment is improved, and safety accidents are avoided.
Description
Technical field
The utility model relates to a kind of ladle long nozzle and burns oxygen device.
Background technology
Steel mill is in the time producing; for the beam between protection ladle and tundish; avoid secondary oxidation and the beam of molten steel to splash; conventionally use long nozzle, long nozzle, after every stove pours, all can form in ladle long nozzle bowl portion the cold steel of thin layer; this layer of cold steel can cause contacting between ladle nozzle and ladle long nozzle not tight; cause secondary oxidation of steel, cause that molten steel O in tundish, N content raise, and even can cause molten steel chemical composition to worsen in serious situation.The control measure that at present steel mill is taked are, manually take off large bag long nozzle, use large bag to burn the sparking of oxygen pipe and burn the cold steel that long water gap bowl part adheres to.Traditional burning oxygen Guan Weiyi root tubule, purges area little, and oxygen pressure is large, and the artificial grasp size that is difficult for, needs certain skill.The spray of molten steel splashing is irregular, easily scalds staff.Ladle long nozzle is difficult for cleaning out, and can only feel with operating personnel.It is long to burn the cold steel time, and labor intensive is larger, and energy resource consumption is also larger, and result of use is bad.
Summary of the invention
The purpose of this utility model is to provide a kind of ladle long nozzle to burn oxygen device, and it is simple in structure, can make oxygen blow area strengthen, and intensity reduces, reduce purge time, improve and purge effect, and can save manpower, material resources, improve the working environment of workers, prevent that security incident from occurring.
The purpose of this utility model is to realize like this, a kind of ladle long nozzle burns oxygen device, comprise oxygen lance, the purging end of oxygen lance is connecting one and is being hemispheric shower nozzle, the bottom surface of shower nozzle is plane, the uniform interval that is centrosymmetric on the bottom surface of shower nozzle is arranging spray orifice, and the aperture of spray orifice is 1.5mm, and the bottom surface external diameter of shower nozzle is less than the wrist external diameter of ladle long nozzle.
The utility model (1) has been simplified burning oxygen process, has reduced the technical ability requirement to burning oxygen work, personnel's simple training on duty.(2) reduce the consumption of original steel pipe, monthly reduced and consume approximately 10,000 yuan, can reduce the supplies consumption of steel mill.(3) effectively reduce workman's labour intensity, greatly improved the working environment of workers, greatly reduce workman's probability of burning, for worker provides safer environment-guarantee.(4) improve steel quality, improve continuous casting billet inherent quality.It is simple in structure, can make oxygen blow area strengthen, and intensity reduces, and reduces purge time, improves and purges effect, and can save manpower, and material resources, improve the working environment of workers, prevents that security incident from occurring.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is perspective view of the present utility model.
Detailed description of the invention
A kind of ladle long nozzle burns oxygen device, as shown in Figure 1, comprise oxygen lance 1, the purging end of oxygen lance 1 is connecting one and is being hemispheric shower nozzle 2, the bottom surface of shower nozzle 2 is plane, the uniform interval that is centrosymmetric on the bottom surface of shower nozzle 2 is arranging spray orifice, and the aperture of spray orifice is 1.5mm, and the bottom surface external diameter of shower nozzle 2 is less than wrist 4 external diameters of ladle long nozzle 3.
Claims (1)
1. a ladle long nozzle burns oxygen device, comprise oxygen lance, it is characterized in that: the purging end of oxygen lance is connecting one and is being hemispheric shower nozzle, the bottom surface of shower nozzle is plane, the uniform interval that is centrosymmetric on the bottom surface of shower nozzle is arranging spray orifice, the aperture of spray orifice is 1.5mm, and the bottom surface external diameter of shower nozzle is less than the wrist external diameter of ladle long nozzle.
