Abstract
It the utility model is related to a kind of converter oxygen gun specialized barrel, including passing through affixed two semi-circular tubes for forming round tube of bolt, the internal diameter of the round tube is bigger 0.2 ~ 0.5mm than oxygen gun body diameter, handle is connected with the outer wall of two halves pipe, the handle is offered along the axially extending strip hole of round tube respectively on the semicircle tube wall of both sides up and down.The utility model has the advantages of simple structure, easy to manufacture and repair；Material therefor is few, cheap, can Reusability, reduce production cost；It is convenient using this casing operations, it securely and reliably, can greatly shorten oxygen rifle outer tube, pipette tips replacing construction, improve operating efficiency；Oxygen rifle is made using this casing, gun body replaces position, pipette tips and the accurate centering of outer tube connecting portion energy and fixation, hence it is evident that improves oxygen rifle production quality.
Description
Technical field
Steelmaking equipment auxiliary Tools Technology is the utility model is related to, more particularly to a kind of converter oxygen gun replaces outer tube
And the specialized barrel used during pipette tips.
Background technology
Oxygen rifle is the capital equipment of converter smelting, it is made of 3 layers of concentric pipe, in removable parts outer tube and oxygen rifle rifle
During head, when connection between outer tube and outer tube and between pipette tips and outer tube, centering fixed charge, is longer, has seriously affected oxygen rifle system
The time of work and quality.At this stage, major steel mill is to use to visually observe mode when replacing outer tube, oxygen rifle pipette tips, this is just
Result in oxygen gun body bending, pipette tips it is out of alignment, cause production quality poor, using effect is bad.
The content of the invention
The utility model is in view of the deficiencies of the prior art, there is provided a kind of converter oxygen gun specialized barrel, can quickly carry out oxygen
The replacement of rifle outer tube and pipette tips.
The utility model is achieved by the following technical solution, there is provided a kind of converter oxygen gun specialized barrel, including pass through
Affixed two semi-circular tubes for forming round tube of bolt, the internal diameter of the round tube is bigger 0.2 ~ 0.5mm than oxygen gun body diameter, two halves
Handle is connected with the outer wall of pipe, the handle is offered along round tube respectively on the semicircle tube wall of both sides up and down axially to be prolonged
The strip hole stretched.
This programme when in use, by two semicircular pipe sleeve on new oxygen rifle outer tube and pipette tips, is fastened with bolt, then passes through length
Bar hole is welded, and be ensure that aligning for pipette tips, and convenient operation, is improved replacement efficiency.
As an optimization, two halves pipe joint is installed with connection otic placode, and the bolt is threaded through the connection on two halves pipe
On otic placode.Make connection and the dismounting of two halves pipe more convenient, save replacing construction.
Preferably, the circle length of tube is 30 ~ 35cm.When the setting of this length both ensure that replacement to being about to
Ask, turn avoid it is long caused by waste of material.
The beneficial effects of the utility model are：It is simple in structure, easy to manufacture and repair；Material therefor is few, cheap, can
Reusability, reduces production cost；It is convenient using this casing operations, securely and reliably, it can greatly shorten oxygen rifle outer tube, pipette tips are replaced
Time, improves operating efficiency；Oxygen rifle is made using this casing, gun body is replaced position, pipette tips and outer tube connecting portion and can accurately be looked for
It is just and fixed, hence it is evident that to improve oxygen rifle production quality.

Embodiment
In order to clarify the technical characteristics of the invention, below by embodiment, this programme is illustrated.
A kind of converter oxygen gun specialized barrel as shown in Figure 1, including pass through affixed two stainless steels for forming round tube of bolt 3
Semi-circular tube 4, the internal diameter of the round tube is bigger 0.2mm than oxygen gun body diameter, and circular length of tube is 30cm, two halves pipe 4 it is outer
Handle 5 is connected with wall, the handle is offered along the axially extending length of round tube respectively about 5 on the semicircle tube wall of both sides
Bar hole 2.4 joint of two halves pipe is installed with connection otic placode 1, and the bolt 3 is threaded through in the connection otic placode on two halves pipe.
When replacing oxygen rifle outer tube, this casing is placed in outer tube connecting portion, casing is fixed with 4 bolts；Tighten bolt
When, this casing carries out centering to connecting portion automatically and fixes；Connecting portion is welded and fixed by the strip hole on casing；
This casing is removed, full weld processing then is carried out to connecting portion.
When replacing oxygen rifle pipette tips, pipette tips inner tube is inserted into oxygen rifle inner tube, this casing is placed in pipette tips and outer tube connecting portion,
Bolt is tightened, casing carries out centering to connecting portion automatically and fixes；By the strip hole on casing, connecting portion is welded
It is fixed；This casing is removed, full weld processing then is carried out to connecting portion.
Oxygen rifle is made using the utility model, reduces artificial judgement, improves oxygen rifle producing efficiency and quality.
Certainly, described above is also not limited to the example above, and technical characteristic of the utility model without description can lead to
Cross or realize that details are not described herein using the prior art；Above example and attached drawing are merely to illustrate the technology of the utility model
Scheme is not the limitation to the utility model, and the utility model is described in detail with reference to preferred embodiment, this
Field it is to be appreciated by one skilled in the art that those skilled in the art institute in the essential scope of the utility model
For the variations, modifications, additions or substitutions made without departure from the objective of the utility model, the right that should also belong to the utility model will
Seek protection domain.
