Abstract
The utility model relates to an oxygen lance spray head with a novel structure (achieved by squeezing and casting), comprising a spray-head end cap, a lower distributor cone, an oxygen jet hole, a water guide plate, an oxygen distribution head, an upper distributor cone and an oxygen inlet pipe. The spray-head end cap and the column body of the oxygen jet hole are squeezed into one body; the oxygen distribution head is moulded by casting; the water-spray end cap and the column body of the oxygen-spray hole are squeezed into a single box; the oxygen distribution head is a separate box; therefore, the structure has two boxes. The oxygen distribution head and the oxygen inlet pipe are two separate bodies welded together by different materials; a slot linking the water inlet pipe is arranged on the water guide plate; a crater connected to the water outlet pipe is prepared on the outside diameter of the spray-head end cap. The utility model is characterized in two-box structure (achieved by squeezing and casting), simple structure and fabrication process, few welding seams, high security, high finished product rate (above 95percent), low copper consumption and cost, and long service life.
Description
Technical field
The utility model relates to a kind of Oxygen Lance Nozzle for Converter of novel texture---and built-up type squeezes-the casting oxygen lance blow head.
Background technology
Along with the expansion of the progress and development of converter steeling technology, particularly converter capacity and the raising of combustion intensity, to porous, manufacturing technology develops into casting from forging (during single hole) to the oxygen rifle, so that present built-up type by single hole.Forge shower nozzle and be applicable to single hole, be eliminated; The casting shower nozzle is owing to the reason of casting itself, the low and pore of density, sand holes, inevitably defective such as loose, the shower nozzle life-span still can not satisfy the converter production development needs, particularly slag splashing " permanent furnace lining " appearance and all require to improve the shower nozzle life-span for the needs of realizing automation of converter steel-making; Built-up type shower nozzle pattern has the built-up type forging and pressing shower nozzle of external Germany, belongs to three box structures, employing be forging forming, not enough point is easy sealing-off, yield rate is low and price is expensive; Domestic have two box structures, the built-up type shower nozzle of extruding and die-forging forming, and actual is forme fruste two box structures, because it is that the oxygen spraying hole cylinder is welded in earlier on the retaining plate, and is welded together with the oxygen shunt head again, need secondary welding, the possibility that still has sealing-off, oxygen hole to leak, manufacturing process are still complicated.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned practical problems, and a kind of more reasonable structure is provided, and manufacturing process is simpler, and yield rate height, the built-up type that copper loss is few, cost is low and the life-span is high squeeze-the casting oxygen lance blow head.
The purpose of this utility model is achieved in that
A kind of built-up type squeezes-the casting oxygen lance blow head, comprise the shower nozzle end cap, under divide water awl, oxygen spraying hole, guide water board, the oxygen shunt head, the last water awl that divides, feeding oxygen tube, the nozzle end cover tape has following minute water awl, the cylindrical body of shower nozzle end cap and oxygen spraying hole is that extrusion molding and extruding are one, the oxygen shunt head has branch water awl, the oxygen shunt head is a casting, the cylindrical body of oxygen spraying hole is connected with the soldering of oxygen shunt head, oxygen shunt head and feeding oxygen tube are welded to connect, have " O " type O-ring seal on the feeding oxygen tube, the shower nozzle end cap, the cylindrical body of oxygen spraying hole, the oxygen shunt head adopts copper material, feeding oxygen tube adopts steel material, be equipped with guide water board outside the cylindrical body of oxygen spraying hole, guide water board is provided with the slot that is connected with water inlet pipe, and shower nozzle end cap external diameter leaves the weld bond that is connected with rising pipe.
Characteristics of the present utility model are:
Adopt to squeeze-casting bonded two box structures, have structure, manufacturing process is simple, weld seam is few, the safety performance height, and the yield rate height reaches more than 95%, and copper loss is low, and cost is low, the mixed economy of long service life and result of use.
