Abstract
The utility model discloses a combined type extrusion center water-cooled electric furnace oxygen lance nozzle, which comprises a nozzle end cover, an oxygen jet tube, a drain plate, a braze welding, an externally connected pipe, a medium connected pipe, an oxygen shunt head, an internally connected pipe, a limit bar and a steel tube and so on. The nozzle end cover and the oxygen jet tube are extrusion integral parts which are linked with the oxygen shunt head through the braze welding. The two-box structure of the main body is molded once. The drain plate is mounted on the oxygen jet tube and is welded with the medium connected pipe; the oxygen shunt head is welded with the internally connected pipe; the external diameter of the nozzle end cover is welded with the externally connected pipe which is then welded with the steel tube. The limit bar arranged on the external wall of the medium connected pipe is welded with the internal wall of the externally connected pipe. The nozzle is simple in manufacture process and low in cost and can properly add more oxygen jet tubes. In addition, the nozzle has service life more than 1time to 3 times that of casting nozzles and remarkable overall economic efficiency, which can be applied and promoted in the smelting industry.
Description
The utility model belongs to the Electric furnace steel making production unit---a kind of built-up type extruding center water-cooled electric furnace oxygen lance blow head.
At present, home and abroad electric furnace oxygen lance blow head technology has had very much progress.First-generation product, it is superseded to forge the electric furnace shower nozzle, and how s-generation product teeming furnace shower nozzle owing to about work-ing lifes 30～100 heats, be to realize the steel-making automatization, solves the demand that adapts to electrosmelting; Developing third generation electric furnace oxygen lance blow head product is the manufacturing task of top priority of oxygen rifle.
The purpose of this utility model is at above-mentioned practical problems, provides that a kind of manufacturing process is simple, cost is low, yield rate is high, is applicable to the built-up type extruding center water-cooled electric furnace oxygen lance blow head of big flow oxygen supply smelting requirements.
Technical solutions of the utility model are to realize like this, the utility model discloses a kind of built-up type extruding center water-cooled electric furnace oxygen lance blow head, form by shower nozzle end cap, jetting oxygen tube, guide water board, oxygen gas head shunt head, inner connecting tube, middle adapter, extension tube attached, spacing muscle, steel pipe, it is characterized in that: shower nozzle end cap and jetting oxygen tube are the extruding integral piece, and jetting oxygen tube is that two box structure solderings connect once shaped with oxygen shunt head main body; Shower nozzle end cap external diameter and extension tube attached (copper tube) welding, extension tube attached is welded with steel pipe again, on middle adapter outer wall spacing muscle is set, and spacing muscle connects with the welding of extension tube attached inwall.
Characteristics of the present utility model are simple in structure, and (two box structures) technology is reasonable, and cost is low, and safety performance is good, and be 1～3 times of teeming furnace shower nozzle work-ing life, and overall economic efficiency is remarkable, can use in electrosmelting industry.
Below in conjunction with accompanying drawing and specific implementation method the utility model is described in detail:
Fig. 1 is for shown in the cold electric furnace oxygen lance blow head structural profile synoptic diagram of built-up type extruding center.
Embodiment:
The utility model built-up type extruding center water-cooled electric furnace oxygen lance blow head (see figure 1) is made up of shower nozzle end cap 1, jetting oxygen tube 2, guide water board 3, soldering 4, extension tube attached 5, middle adapter 6, oxygen shunt head 7, inner connecting tube 8, spacing muscle 9, steel pipe 10 etc.Wherein, shower nozzle end cap (1) is the extruding integral piece with jetting oxygen tube (2), and this part is to connect main body two box structure once shapeds by soldering (4) with connecting of oxygen shunt head (7).Go up assembling guide water board (3) at jetting oxygen tube (2), guide water board (3) connects with middle adapter (6) welding, and oxygen shunt head (7) connects with inner connecting tube (8) welding, and the external diameter of shower nozzle end cap (1) connects with the welding of extension tube attached (5) copper tube.Extension tube attached (5) is welded with steel pipe (10) again.Spacing muscle (9) is set on the outer wall of middle adapter (6) to be connected with the welding of extension tube attached (5) inwall.When entering oxygen shunt head (7) by inner connecting tube (8), oxygen passes through jetting oxygen tube (2) when bath disperses oxygen supply, water coolant also enters guide water board (3) by middle adapter (6) to be passed through under the effect of guide water board (3), to jetting oxygen tube (2) and evenly cooling of shower nozzle end cap (1), return by extension tube attached (8) at last, elementary stream is reasonable, good cooling results.Test-results shows; Electric furnace shower nozzle outside dimension is when φ 120mm is above: can select between 9 °～30 ° according to smelting requirements condition shower nozzle center and jetting oxygen tube center angle α.1～3 jetting oxygen tube can be set as required.Help improving the oxygen lance blow head life-span.
Claims (3)
