Description
Technical field
The utility model relates to a kind of stainless steels to burn oxygen spray head, belong to smelting iron and steel device preparation field.
Background technique
In field of steel-making, the big packet long nozzle of continuous casting is needed often clear in use due to splash etc.
It washes, internal residual steel is cleaned up, guarantee the smooth stabilization of steel stream.Usually there are two types of modes for cleaning in the prior art, a kind of
It is to interrupt production, big packet long nozzle is sufficiently cleaned, however this kind of cleaning method is produced due to interrupting, and can be brought to production
Very big waste, seriously reduces production efficiency, it is impossible to ensure that more furnace continuous castings, do not give full play to the superiority of continuous casting,
Second of cleaning way is the interruption to avoid production, usually using the 1-2 minutes for changing packet, due to the cleaning mouth of a river when
Between pretty nervous, therefore it is required that The faster the better for cleaning process and scavenging period；The method of traditional wash water mouth is with burning oxygen side
Formula is handled, and is needed worker to hold curved oxygen hose and be directly protruding into long nozzle and burn oxygen cleaning, in this way clearly
Big packet long nozzle is washed since the most oxygen of oxygen spray pressure ambassador is blown into molten steel, causes middle Baogang's water by secondary oxygen
Change, while oxygen pipe must be moved in long nozzle inner cavity in cleaning process, operating process easily causes the resistance to material scaling loss of long nozzle
And the perforation of long nozzle neck is caused to scrap.
Summary of the invention
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of simple structure and reasonable design, it is easy to disassemble,
Efficiently quickly stainless steel burns oxygen spray head.
Purpose of the utility model is realized as follows:
A kind of stainless steel burning oxygen spray head, includes head body, and the head body is in truncated cone-shaped, the cross of the head body
Section becomes larger from top to bottom, above-mentioned head body inner hollow；The outer wall of the head body is equipped with annular flange, described
Annular flange and head body are coaxially disposed, and the outer diameter of the annular flange is greater than the rim of a bowl diameter of long nozzle；The spray head sheet
The bottom surface of body is equipped with multiple evenly arranged stomatas；The top surface of the head body is equipped with bend pipe, the bending angle of the bend pipe
It is 90 °, one end of the bend pipe is connected with head body, and the other end of bend pipe is connected with oxygen pipe；Oxygen pipe passes through soft into oxygen
Pipe is connected with oxygen tank；
A kind of stainless steel of the utility model burns oxygen spray head, and the stomata is cross section gradually smaller truncated cone-shaped from top to bottom
Structure；
A kind of stainless steel of the utility model burns oxygen spray head, and the end outer wall of the bend pipe and oxygen pipe junction are equipped with outer spiral shell
The front end of line, the oxygen pipe is equipped with corresponding internal screw thread with bend pipe junction, and bend pipe is screwed on oxygen pipe by screw thread；
Compared with prior art, the utility model has the beneficial effects that
The utility model directly burns oxygen, the spray of oxygen via through holes instead of traditional oxygen pipe by the way that truncated cone-shaped is burnt oxygen spray head
Out, speed faster, more evenly, keeps purging more abundant, reduces the damage of long nozzle and scrap ratio；Simultaneously by oxygen nozzle with
Oxygen pipe is screwed on by screw thread, easy to disassemble, and the spray head of different bores or the oxygen of different length can be replaced according to real work demand
Pipe, simple structure and reasonable design, it is easy to disassemble, efficiently quickly.
Detailed description of the invention
Fig. 1 is the schematic perspective view that a kind of stainless steel of the utility model burns oxygen spray head.
Fig. 2 is the cross-sectional view that a kind of stainless steel of the utility model burns oxygen spray head.
Wherein:
Head body 1, annular flange 2, stomata 3, bend pipe 4, external screw thread 4.1, oxygen pipe 5, internal screw thread 5.1
Specific embodiment
Referring to Fig. 1~2, the utility model relates to a kind of stainless steel burn oxygen spray head, include head body 1, the spray head
Ontology 1 is in truncated cone-shaped, and the cross section of the head body 1 becomes larger from top to bottom, above-mentioned 1 inner hollow of head body；Institute
The outer wall for stating head body 1 is equipped with annular flange 2, and the annular flange 2 is coaxially disposed with head body 1, the annular flange 2
Outer diameter be greater than long nozzle the rim of a bowl diameter, annular flange 2 covers the rim of a bowl when head body 1 is placed at long nozzle the rim of a bowl；It is described
The bottom surface of head body 1 is equipped with multiple evenly arranged stomatas 3, and oxygen is uniformly sprayed by stomata 3 enters long nozzle inner cavity, right
Intracavitary cold steel carries out burning oxygen processing；The top surface of the head body 1 is equipped with bend pipe 4, and the bending angle of the bend pipe 4 is 90 °,
One end of the bend pipe 4 is connected with head body 1, and the other end of bend pipe 4 is connected with oxygen pipe 5；Oxygen pipe 5 is by into oxygen hose
It is connected with oxygen tank valve；Above-mentioned head body 1, bend pipe 4 and oxygen pipe 5 are stainless steel material；
Further, the stomata 3 is cross section gradually smaller truncated cone-shaped structure from top to bottom, and oxygen is squeezed through stomata 3
It is sprayed after pressure, jet velocity is faster；
Further, the end outer wall of the bend pipe 4 and 5 junction of oxygen pipe are equipped with external screw thread 4.1, before the oxygen pipe 5
With 4 junction of bend pipe equipped with corresponding internal screw thread 5.1, bend pipe 4 is screwed on oxygen pipe 5 by screw thread at end, easy to disassemble, can be according to making
The oxygen pipe 5 of different length or the spray head of different bores are replaced with situation；
Working principle:
When burning oxygen, head body 1 is placed at long nozzle the rim of a bowl, annular flange 2 is made to cover long nozzle the rim of a bowl, opens oxygen
Gas tank valve starts to burn oxygen cleaning.
In addition: it should be noted that above-mentioned specific embodiment is only a prioritization scheme of this patent, the skill of this field
Any change or improvement that art personnel are done according to above-mentioned design, within the protection domain of this patent..
