Abstract
The utility model provides an oxygen rifle shower nozzle for oxygen blows converter to one side, comprises a spray nozzle, the embedded L type gas that is equipped with of shower nozzle is said, the upper and lower below symmetry that the gas was said is equipped with into oxygen way, the afterbody that advances oxygen way is equipped with out oxygen way, advance oxygen way, go out contained angle between the oxygen way the same with the angle of buckling that the gas was said, the radius that goes out oxygen way reduces along with the air current direction gradually. The utility model discloses can make flame and fire door bonding abundant contact to make the oxygen passageway clearance between natural gas nozzle and the copper shower nozzle even, reduce the mutual interference of air current and strengthened natural gas flame rigidity, avoid melting the fire door and appear bonding.
Description
Technical Field
The utility model belongs to the technical field of mining industry is smelted, a oxygen rifle shower nozzle for oxygen oblique blowing converter is related to.
Background
With the popularization of novel energy sources, natural gas gradually replaces heavy oil as fuel energy source to carry out production organization. Due to 1231Nm3The heat provided by the combustion of natural gas is equivalent to 1 ton of heavy oil, the original oxygen lance nozzle can not meet the bonding requirement of a melting furnace mouth in the production process of a Kaldo furnace, the problems of insufficient flame rigidity of a combustion gun, long temperature raising time and the like occur, the temperature can not reach an expected target value (the melting point of cuprous sulfide is about 1130 ℃) when the bonding material is melted at the furnace mouth, the heavy oil melting furnace mouth is melted after 60 minutes, the surface of the bonding material is melted and uneven after the natural gas is used for melting the furnace mouth for 80 minutes, the bonding material can not be melted, the lining body at the furnace mouth is damaged, the service life of the furnace lining is reduced, and the overhaul cost of the furnace lining is increased.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a to the problem that prior art exists, provide an oxygen rifle shower nozzle for oxygen blows converter to one side, solved current burning gun flame rigidity inadequately, lead to the unable quilt of bonding thing to be melted problem.
Therefore, the utility model adopts the following technical proposal:
an oxygen lance nozzle for an oxygen oblique blowing converter comprises a nozzle, wherein an L-shaped gas channel is embedded in the nozzle, oxygen inlet channels are symmetrically arranged above and below the gas channel, an oxygen outlet channel is arranged at the tail part of the oxygen inlet channel, the included angle between the oxygen inlet channel and the oxygen outlet channel is the same as the bending angle of the gas channel, and the radius of the oxygen outlet channel is gradually reduced along with the airflow direction.
Further, the bending angle of the gas channel is not more than 18 degrees.
Further, the aperture of the gas channel is not more than 32 mm.
Further, the pore diameter of the oxygen outlet channel is not more than 6 mm.
Further, the spray head is made of copper.
The beneficial effects of the utility model reside in that:
the utility model discloses can make flame and fire door bonding abundant contact to make the oxygen passageway clearance between natural gas nozzle and the copper shower nozzle even, reduce the mutual interference of air current and strengthened natural gas flame rigidity, avoid melting the fire door and appear bonding.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1-a spray head, 2-a gas channel, 3-an oxygen inlet channel and 4-an oxygen outlet channel.
Detailed Description
The technical solution of the present invention will be described below with reference to the accompanying drawings and implementation methods.
As shown in fig. 1, an oxygen lance nozzle for an oxygen oblique blowing converter comprises a copper nozzle 1, an L-shaped gas channel 2 is embedded in the nozzle 1, the bending angle of the gas channel 2 is 18 degrees, oxygen inlet channels 3 are symmetrically arranged above and below the gas channel 2, an oxygen outlet channel 4 is arranged at the tail part of the oxygen inlet channel 3, and the included angle between the oxygen inlet channel 3 and the oxygen outlet channel 4 is the same as the bending angle of the gas channel; furthermore, the aperture of the gas channel 2 is 32mm, the radius of the oxygen outlet channel is gradually reduced along with the airflow direction, the maximum aperture is 6mm, and the minimum aperture is 3 mm.
The utility model discloses need install in oxygen rifle tip to install the oxygen blowing device on the fire door of oxygen oblique blowing converter when the use, when melting the fire door operation, oxygen passes through shower nozzle 1 and spouts in the stove, with the gas mixed combustion in 2, effectively clears away the fire door, has alleviateed and has melted the bonding in-process, to the erosion of fire door, has improved fire door bonding thing melting efficiency.
