| titleOfInvention | A kind of double fluid stock oxygen rifle and its application method |
| abstract | A kind of improvement pneumatic steelmaking thermal efficiency so as to improve converter cold burden than, slugging effect and the double-current stock oxygen lance nozzle and its application method of the new structure of outlet temperature hit rate, belongs to the technical field of pneumatic steelmaking.Oxygen rifle main aperture and secondary orifices are on nozzle.In the oxygen intake direction of nozzle, the major and minor hole count of oxygen intake is identical, but on nozzle oxygen outlet direction, main aperture number is constant, and secondary orifices outlet number then can be 13 times of secondary orifices entrance.The main aperture number of spray outlet is 36, and secondary orifices number is 6 15.Main aperture flow, which accounts for, always supplies more than the 85% of flow, and secondary orifices flow accounts for total oxygen supply and is less than 15%.The export direction of secondary orifices is not restricted by secondary orifices Way in, but multidirectional, you can downward, horizontal can also be upward, so as to substantially increase the post-combustion rate of converter.During oxygen lance operation, blowing rifle position is higher than 100 200mm of traditional rifle position, splashes slag rifle position and is higher than 50 100mm of traditional oxygen lance position. |
