Description
Technical field
This utility model relates to a kind of preventing the device of Metal in Tundish secondary oxidation during continuous casting is opened and watered, and belongs to even
Casting tundish apparatus technical field.
Background technology
In STEELMAKING PRODUCTION, continuous casting is the process that molten steel solidification becomes strand.During continuous casting, first ladle is rested upon revolution
On platform, then rotating to tundish side, package big bag long nozzle, open slide plate, molten steel flows into tundish along big bag long nozzle
In, through the shunting action of tundish, make molten steel flow in crystallizer along submersed nozzle.In the process, molten steel and air
Contact can occur the secondary oxidation of molten steel, and molten steel is made the inclusion content in molten steel raise by air secondary oxidation, thus leads
Cause middle water containing opening wadding stream, even cause conticaster to stop watering.
The mechanism of molten steel generation secondary oxidation is: during continuous casting the first stove is opened and watered, after molten steel enters tundish, right
Tundish carries out Argon, to empty the air of tundish, uses coverture to cover liquid steel level simultaneously, prevents molten steel oxidation.For
Coverture is prevented to be involved in molten steel, it is necessary to when tundish molten steel face height reaches 400mm, operator could be to centre
Coverture is added in bag.Tundish owing to coordinating eight machine eight strand casting machine to use is longer, only by carrying out tundish both sides
Blowing argon gas empty, the air in tundish centre can not be replaced discharge completely, thus from unwrap greatly water to coverture complete
In this period of time of all standing molten steel face, middle part molten steel is in naked state in tundish, and molten steel easily and air contact, causes
Secondary oxidation of steel.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of device preventing Metal in Tundish secondary oxidation, this
Plant device and in continuous casting early stage, tundish can be carried out Argon emptying, molten steel is implemented argon envelope protection, to reduce tundish
Open the secondary oxidation of molten steel during watering, reach the purpose of cast of stable casting machine initial stage effect.
The technical scheme solving above-mentioned technical problem is:
A kind of device preventing Metal in Tundish secondary oxidation, it is by argon delivery lines, metal hose, oxygen lance, argon
Valve forms, and argon delivery lines is long metal tube, and argon delivery lines lies in a horizontal plane on tundish cover, the rear end of metal hose
Being connected on the body of rod of argon delivery lines, the front end of metal hose is connected with oxygen lance, and the forward vertical of oxygen lance is turned under
Folding, the front end of oxygen lance extend in tundish, and the rear end of argon delivery lines is connected with argon pipeline, argon delivery lines and argon
The connection end of feed channel is provided with argon valve.
The above-mentioned device preventing Metal in Tundish secondary oxidation, described metal hose and oxygen lance are the most multiple, multiple
Metal hose is uniform along the length direction of argon delivery lines, and multiple metal hoses are connected with multiple oxygen lances coupling respectively.
The beneficial effects of the utility model are:
This utility model in use argon is respectively enterd in each metal hose by argon delivery lines, finally leads to
Cross oxygen lance to enter in tundish, owing to oxygen lance is dispersed in each position of tundish, open water early stage can be the most right
In tundish, air carries out displacement emptying, before liquid level is completely covered by, big covering agent stable in tundish molten steel face, can in
Between Baogang ullage form one layer of argon gas blanketing, air is isolated with molten steel, is effectively prevented secondary oxidation of steel, thus carries
High Molten Steel Cleanliness, reduces inclusion content of steel and opens and water the risk stopping watering, ensureing that continuous casting is the most normally opened and water.This practicality is new
Type simple in construction, can be rapidly assembled and disassembled, and facilitates operator to use.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present utility model；
Fig. 2 is the right view of Fig. 1.
In figure, labelling is as follows: tundish 1, argon delivery lines 2, metal hose 3, oxygen lance 4, argon valve 5, argon pipeline

Detailed description of the invention
This utility model is made up of argon delivery lines 2, metal hose 3, oxygen lance 4, argon valve 5.
Showing in figure, argon delivery lines 2 is long metal tube, and argon delivery lines 2 lies in a horizontal plane on tundish 1 clad.Argon
The rear end of letter shoot 2 is connected with argon pipeline 6, and argon delivery lines 2 is provided with argon valve with the connection end of argon pipeline 6
5.Argon valve 5 controls to carry argon in argon delivery lines 2.
In figure show, the rear end of metal hose 3 is connected on the body of rod of argon delivery lines 2, the front end of metal hose 3 with blow
Oxygen pipe 4 is connected.Metal hose 3 and oxygen lance 4 are the most multiple, and multiple metal hoses 3 are along the length side of argon delivery lines 2
To uniform, multiple metal hoses 3 are connected with multiple oxygen lances 4 coupling respectively.
Showing in figure, the forward vertical of oxygen lance 4 bends downwards, and the front end of oxygen lance 4 extend in tundish 1, argon
Respectively enterd in each metal hose 3 by argon delivery lines 2, enter in tundish 1 finally by oxygen lance 4.
Showing in figure, above-mentioned argon delivery lines 2, metal hose 3, oxygen lance 4, argon valve 5 are two sets, are individually positioned in
The both sides of tundish 1.Owing to multiple oxygen lances 4 are dispersed in each position of tundish 1, open water early stage can centering effectively
Between wrap air in 1 and carry out displacement emptying, create an atmosphere of inert gases for tundish 1.After molten steel enters tundish 1, cover
Agent is not completely covered in face of molten steel, and argon forms one layer of argon envelope in molten steel face, is effectively prevented secondary oxidation of steel, reduces
Inclusion content of steel waters, with opening, the risk stopping watering.
Use process of the present utility model is as follows:
Continuous casting machine debugging is complete, and tundish 1 is opened to working position, is put by the argon delivery lines 2 being connected to metal hose 3
It is placed on tundish 1 clad, operator the oxygen lance 4 after bending is connected with metal hose 3, then by oxygen lance 4 edge
Stopper inserts in tundish 1.Afterwards argon delivery lines 2 is connected with argon pipeline 6, opens argon valve 5, in tundish 1
It is passed through argon and carries out displacement emptying.
Ladle goes to open slide plate after working position installs protection sleeve pipe and unwraps greatly and water, and molten steel flows in tundish 1, molten steel
Enter after tundish 1 and reach the requirement degree of depth, lift stopper tundish 1 and open and water.Owing to argon is distributed in tundish 1 regional,
Can preferably prevent molten steel and air contact, thus reduce the secondary oxidation of molten steel.When steel level reach a certain height, to
Add coverture in tundish 1, after tundish 1 molten steel face is covered by be covered dose completely, close argon valve 5, pull up oxygen blast
Pipe 4, unloads argon delivery lines 2.
