Abstract
The utility model discloses a novel oxygen lance for steelmaking, which relates to the technical field of steelmaking machinery. One end of an inner tube (4) is communicated with an oxygen feeding branch pipe (3), the outer side of the inner tube (4) is provided with an outer tube (6); the outer tube (6) is respectively communicated with a water discharging tube (1), a water supply tube (2) and a water circulation pipeline (5); the other end of the inner tube (4) is provided with a nozzle (7), the nozzle (7) is internally provided with a conical disc (9), an oxygen through hole (10) is formed in the conical disc (9), the outer side of the conical disc (9) is provided with an oxygen intake (11), and the front end of the conical disc (9) is provided with a spiral connector (8). The novel oxygen lance for steelmaking is simple in structure, an oxygen blowing port is designed to be inclined, spiral spraying angle of oxygen is increased, utilization rate of oxygen is increased, molten metal drips are not liable to be adhered on the nozzle and the oxygen lance, and thus, metal yield is increased.
Description
Technical field:
The utility model relates to steel-making field of mechanical technique, is specifically related to a kind of Novel steelmaking oxygen rifle.
Background technology:
Oxygen rifle, is one of main technique equipment in oxygen converter steelmaking, and its performance characteristic directly has influence on metallurgical effect and duration of blast, thereby has influence on the Quality and yield of steel.Oxygen rifle is by oxygen jet, to flow thigh to realize with the interaction in molten bath to the influence of blowing, and velocity magnitude and the distribution thereof of this effect when depending primarily on jet and arriving weld pool surface, so the optimizing of the various process parameters of oxygen lance blow head and the optimization design of structure extremely important.Application Areas: oxygen rifle is mainly used in steel industry, metallurgy industry etc.At present, the mode of oxygen therapy is water-cooled furnace door oxygen therapy, but oxygen utilization rate is lower, and Oxygen Flow is impacted molten steel and caused splash, time have the accident of scalding staff to occur, safety performance is poor.And current oxygen lance blow head mostly is and directly blows type, and oxygen blast hole is parallel with oxygen lance blow head medullary ray, and oxygen is blown into molten steel with parallel state, molten steel does not rotate in stove, and molten steel stirs inhomogeneous, and molten drop is easily bonded on shower nozzle and oxygen rifle, metal yield is low, and duration of blast is long.
Utility model content:
The purpose of this utility model is to provide a kind of Novel steelmaking oxygen rifle, and it is simple in structure, and the angle of oxygen blast mouth adopts inclined design, increased the spiral spray angle of oxygen, improved the utilization ratio of oxygen, made molten drop be difficult for being bonded on shower nozzle and oxygen rifle, thereby improved metal yield.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises rising pipe 1, water inlet pipe 2, enter oxygen arm 3, inner tube 4, ventilating water pipe 5, outer tube 6, shower nozzle 7, spiral connecting joint 8, conical disc 9, oxygen through hole 10 and oxygen feeder 11, one end of inner tube 4 with enter oxygen arm 3 and be communicated with, the arranged outside of inner tube 4 has outer tube 6, outer tube 6 respectively with rising pipe 1, water inlet pipe 2 and ventilating water pipe 5 are communicated with, the other end of inner tube 4 is provided with shower nozzle 7, the inside of shower nozzle 7 is provided with conical disc 9, in conical disc 9, be provided with oxygen through hole 10, the arranged outside of conical disc 9 has oxygen feeder 11, and the front end of conical disc 9 is provided with spiral connecting joint 8.
The utlity model has following beneficial effect: it is simple in structure, the angle of oxygen blast mouth adopts inclined design, has increased the spiral spray angle of oxygen, has improved the utilization ratio of oxygen, make molten drop be difficult for being bonded on shower nozzle and oxygen rifle, thereby improved metal yield.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
With reference to Fig. 1, this embodiment is taked following technical scheme: it comprises rising pipe 1, water inlet pipe 2, enter oxygen arm 3, inner tube 4, ventilating water pipe 5, outer tube 6, shower nozzle 7, spiral connecting joint 8, conical disc 9, oxygen through hole 10 and oxygen feeder 11, one end of inner tube 4 with enter oxygen arm 3 and be communicated with, the arranged outside of inner tube 4 has outer tube 6, outer tube 6 respectively with rising pipe 1, water inlet pipe 2 and ventilating water pipe 5 are communicated with, the other end of inner tube 4 is provided with shower nozzle 7, the inside of shower nozzle 7 is provided with conical disc 9, in conical disc 9, be provided with oxygen through hole 10, the arranged outside of conical disc 9 has oxygen feeder 11, and the front end of conical disc 9 is provided with spiral connecting joint 8.
This embodiment has following beneficial effect: it is simple in structure, the angle of oxygen blast mouth adopts inclined design, has increased the spiral spray angle of oxygen, has improved the utilization ratio of oxygen, make molten drop be difficult for being bonded on shower nozzle and oxygen rifle, thereby improved metal yield.
