Embodiment
The designed a kind of multi-functional oxygen lance spray nozzle for converter of the utility model is based on the described converter formula of background technology steel-making principle and state of art, oxygen blast, smelting cold steel with spatter three kinds of technologies of flux shielding and finish by an oxygen rifle.
The structural representation of one of oxygen lance spray nozzle for converter as depicted in figs. 1 and 2 and oxygen rifle completed assembled and diagrammatic cross-section are as seen, this oxygen lance blow head is secured to the jet oral area 1 of oxygen rifle end, mainly comprise with jet oral area 1 connecting head body 21, a plurality of nitrogen jet pipe 22a～22cs and the vane device 23 of detachable continued access on head body 21 that links to each other, wherein head body 21 can be assemblied in the usefulness of doing oxygen supply on the jet oral area 1 for a long time; Nitrogen jet pipe 22a～22c and vane device 23 be then for convenient for assembly on head body 21 alternatively, other processing step that is applied to make steel.This head body 21 be provided with a straight tube being positioned at the center and around three side spouts, this vane device 23 is for having the butterfly pallet of end closure formula hollow cylinder 231, and hollow cylinder 231 upper ends and straight tube sealing are joined, the lower end links to each other by bearing with butterfly pallet, and the butterfly pallet upper surface is provided with the inclination steel disc 232 of 6 flabellum shapes, can rotatablely move with respect to hollow cylinder 231.According to the angle of inclination of different job requirements and inclination steel disc 232, inclination steel disc 232 quantity of this flabellum shape can be reduced to 3,4 or 5.
Above-mentioned set three nitrogen jet pipe 22a～22c connect with three equally distributed side spouts of head body 21 respectively, are used for spraying magnesium oxide particle to lateral angles spattering flux shielding technology adjustablely.The assembling mode of this nitrogen nozzle and side spout is for spinning mutually by " L " type groove correspondingly.Concrete set-up mode can have following two kinds of structures:
One, " L " type groove that the end outside surface that docks with the side spout of this nitrogen jet pipe is provided with and the pipe shaft radial section intersects, the guiding projection that the side spout is provided with is rabbeted into " L " type groove, and damping is therein slided; The two, " L " type groove that the inwall that docks with the nitrogen jet pipe of this side spout is provided with and side spout radial section intersects, the guiding projection of nitrogen jet pipe outer wall correspondence is rabbeted into " L " type groove, and damping is therein slided.Though more than two kinds of structures that spin do not reach diagram, be the conventional basic structure of mechanical industry, so will not give unnecessary details; But there is any should be noted that: the mode that spins that this place adopts damping to slide; and " L " type groove and radial section intersect; the degree of going deep into that event spins along with the nitrogen jet pipe; the angle of its air outlet has controllability; can adapt to the needs that this spatters flux shielding technology better; make saturated or oversaturated magnesium oxide spatter, cool off, solidify, on backup lining brick, form the dystectic slag blanket that spatters of one deck, and make itself and backup lining brick closely cohere, cover by blowing of high pressure nitrogen.Thereby reduce the loss rate of refractory materials, the work-ing life of improving furnace lining.
Further, aforesaid vane device hollow cylinder 231 is provided with the breather hole 233 of hollow out, and the air outlet of the breather hole 233 that quantity is not unique for respectively over against each inclination steel disc 232, so in the technology of smelting cold steel, quicken the oxygen blow out and the uniformity coefficient that improves its smelting cold steel.
The actual job process of above-described oxygen lance blow head is: when oxygen blast, separate stand-by with the nitrogen jet pipe with the head body of multifunctional oxygen lance the vane device, oxygen blast is installed in the vane device on the multifunctional oxygen lance head body by quick buckle when finish needing chilly steel again, drive the oxygen rotation when utilizing the blade rotation and increase the contact area of oxygen and cold steel, thereby remove cold steel quickly; In the time of need spattering flux shielding, the vane device separates with head body, the nitrogen jet pipe is connected with the side spout by special-purpose draw-in groove, thereby the spray angle of change nitrogen reaches the purpose of spattering flux shielding.
This shows that the outstanding advantages of the utility model oxygen gun sprayer is: can save a large amount of changing the rifle time, improve dramatically steel-making efficient, alleviate workman's labour intensity, energy-conserving and environment-protective. And it is convenient that the multifunctional oxygen gun sprayer is changed parts, and a shower nozzle can be finished three different process routes. This technical scheme has broad prospects in pneumatic steelmaking.
