Abstract
The utility model relates to an improvement for the blow head of the oxygen gun of electric furnace steel making equipment belonging to the field of metallurgy, in particular to a single-hole combined blow head which is characterized in that the front end of a shell of the single-hole combined blow head is welded and connected with a steel hemispheric connection body through an oxygen blowing body in an umbrella shape, subsequently, the front end of the shell is connected with an external tube of the oxygen gun. The connection section between the oxygen blowing body and the hemispheric connection body is a vertical section taking the axial line of an oxygen blowing hole as the center. The axial line of the oxygen blowing hole on the blow head forms an included angle Alpha of 10 to 40 degrees with a shaft of the external tube of the oxygen gun. The single-hole combined blow head disclosed in the utility model has the advantages of reasonable structure design, simple production, long service life, long cooper consumption and low production cost. The utility model has large coverage area of air blowing during the process of utilizing the electric furnace to make steel through blowing, in order to reduce the blowing period and save energy.
Description
Technical field the utility model is to the improvement of metallurgy industry electric furnace steel making equipment oxygen gun sprayer design, relates to a kind of single hole combined sprinkler.
What the present domestic metallurgy industry electric furnace steel making of background technology adopted usually is water-cooled single hole oxygen gun sprayer, adopts the non-ferrous metal copper casting to make.This shower nozzle exists in design: the casting shower nozzle is loose, inner surface is slightly made, the internal structure complexity should not be processed, thereby service life is short, and the non-ferrous metal copper consumption is big, production cost is high.
Summary of the invention the utility model has overcome the deficiencies in the prior art, is the metallurgy industry electric furnace steel making, a kind of long service life is provided, saves non-ferrous metal, low, the simple single hole combined sprinkler of manufacturing process of cost.
The utility model single hole combined sprinkler content Description:
The utility model single hole combined sprinkler, form by pipe, oxygen pipe, oxygen blast hole, high pressure inlet channel, high pressure water outlet, weather board in oxygen blast body, hemisphere connector, oxygen rifle outer tube, the oxygen rifle, it is characterized in that: the front end of the housing of single hole combined sprinkler be by non-ferrous metal copper make be shaped as the strong oxygen blast body of umbrella and the hemisphere union body of a steel is welded to connect, weld together with oxygen rifle outer tube again; The section that is connected of oxygen blast body and hemisphere union body is the vertical cross section that is formed centrally in being with the oxygen blast axially bored line; Angle α between oxygen blast axially bored line on the shower nozzle and oxygen rifle outer tube axis is 10～40 ° of angles.
The utility model single hole combined sprinkler, reasonable in design, manufacturing skill down are simple, have the characteristics of long service life, saving non-ferrous metal copper, low cost of manufacture, energy savings.
Description of drawings Fig. 1 is among the single hole combined sprinkler structural representation figure: 1 is weather board for high pressure water outlet, 9 for high pressure inlet channel, 8 for oxygen pipe, 7 for pipe in the oxygen rifle, 6 for oxygen rifle outer tube, 5 for hemisphere connector, 4 for oxygen blast hole, 3 for oxygen blast body, 2.
Specific embodiment the utility model single hole combined sprinkler is to realize like this, see Fig. 1, the single hole combined sprinkler, it is characterized in that: the front end of the housing of single hole combined sprinkler is that the oxygen blast body 1 that is shaped as umbrella made by non-ferrous metal copper and the hemisphere union body 3 of a steel are welded to connect, and welds together with oxygen rifle outer tube 4 again; The section that is connected of oxygen blast body 1 and hemisphere union body 3 is the vertical cross sections that are formed centrally during axis with oxygen blast hole 2 is; The axis of the axis in the oxygen blast hole 2 on the shower nozzle and oxygen rifle outer tube 4 is 10～40 ° of angles.The weather board 9 that is provided with in the housing of shower nozzle is connected with pipe 5 in the oxygen rifle, and pipe 5 is a high pressure water outlet 8 with the interlayer that oxygen rifle outer tube 4 forms in the oxygen rifle; Pipe 5 is a high pressure inlet channel 7 with the interlayer that oxygen pipe 6 forms in the oxygen rifle.
