Abstract
The utility model belongs to the improvement, especially a package be built by contract argon blowing device in middle of continuous slab casting of package be built by contract protection pouring device structure in the middle of the steel mill continuous casting, including that it is installing the be built by contract to wrap the cooperation the continuous casting in the middle of, setting up on the be built by contract and fill in excellent hole and orifice, setting up the through -hole of two symmetries on the be built by contract between excellent hole of stopper and orifice, connecting argon blowing device on the through -hole, horizontal pipe constitution T venturi tube is being connected for the port that blows the argon and be responsible for to argon blowing device's structure, is connecting the standpipe of bending on the port of transversely managing both ends respectively downwards, and two standpipes are connected with two through -holes of be built by contract respectively. The utility model discloses rational in infrastructure, molten steel surface covering one deck the argon protection layer in the middle of can making in the package, effectual isolated molten steel and air, in the middle of reducing in the package molten steel can be improved continuous casting pouring process by the degree of oxidation, improve the continuous casting billet quality.
Description
Technical field
This utility model belongs to the improvement of steel plant continuous casting tundish cover molding casting apparatus structure, particularly a kind of slab CC tundish clad argon-blowing device.
Background technology
Tundish, as steel making working procedure, last contains the container of liquid molten steel, how to play its metallurgical function to greatest extent, is always up continuous casting worker's concern. Tundish molding casting is divided into ladle covering agent protection, ladle long nozzle protection (preventing and treating secondary oxidation), middle covering agent molding casting (absorption is mingled with), middle bag submersed nozzle protection (preventing and treating secondary oxidation), crystallizer protecting residue protection etc.
The tundish originally used is only capable of playing the effect of pushing off the slag, but owing to there is gap between tundish and clad, and the stopper hole on tundish cover, thermometer hole etc., therefore in tundish, liquid steel level directly and air contact, very easily causes the oxidation of molten steel, cause increasing of molten steel subscale field trash, not only continuous casting is poured into a mould and is adversely affected by formation dross phenomenon smoothly, and causes the rising of continuous casting billet inner clamps foreign material, affects continuous casting billet quality.
The subject matter that tradition tundish exists is as follows:
1, owing to there is gap between tundish and clad, and the stopper hole on tundish cover, thermometer hole etc., therefore in tundish, liquid steel level directly and air contact, very easily causes the oxidation of molten steel, causes increasing of molten steel subscale field trash.
2, the field trash that in molten steel, content is higher forms dross phenomenon, and dross thing is enriched in middle water containing opening constantly to be piled up, and causes that aperture, the mouth of a river is plugged, continuous casting is poured into a mould smoothly and adversely affects.
3, the constantly oxidation of Tundish during Continuous Casting causes the rising of continuous casting billet inner clamps foreign material, affects continuous casting billet quality.
Utility model content
The purpose of this utility model is in that to provide a kind of slab CC tundish clad argon-blowing device; it is rational in infrastructure; the molten steel surface in tundish can be made to cover lid layer argon shield; effective isolation molten steel and air; reduce the degree that in tundish, molten steel is oxidized; continuous casting process can be improved, improve continuous casting billet quality.
The purpose of this utility model is achieved in that a kind of slab CC tundish clad argon-blowing device, including coordinating on continuous casting production, clad is installed, clad arranges stopper hole and orifice, clad between stopper hole and orifice arranges two symmetrical through holes, through hole is connected to argon-blowing device, the port that the structure of argon-blowing device is Argon supervisor is connected to transverse pipe composition T-shaped pipe, respectively connected the vertical tube of downward bending on the port at transverse pipe two ends, two vertical tubes are connected with two through holes of clad respectively.
It is as follows that this utility model mainly improves content:
1, pre-buried Argon pipeline on tundish cover, molten steel passes into argon in now the tundish process, at Metal in Tundish liquid level overlying lid layer argon, owing to argon is noble gas, therefore the effect of air-isolation can be played, it is prevented that molten steel is aoxidized by air secondary.
Main improvement effect:
1, the continuous Argon of MOLTEN STEEL FLOW process in tundish, molten steel passes into argon in now the tundish process, at Metal in Tundish liquid level overlying lid layer argon, plays the effect of isolation air, it is prevented that molten steel is aoxidized by air secondary.
2, the degree that the molten steel that can be substantially reduced in tundish after improving is aoxidized by air secondary, reduces the high-melting-point field trash in molten steel in the enrichment of middle water containing opening, contributes to continuous casting and be smoothed out.
3, prevent the secondary oxidation of Tundish during Continuous Casting, reduce the quantity of continuous casting billet inner clamps foreign material, it is ensured that continuous casting billet quality.
4, argon-blowing device is easy for installation, installs with tundish cover, and handling, personnel only need to install argon-blowing device pipe joint, it is possible to decrease the labor intensity of staff.
This utility model is rational in infrastructure, it is achieved that makes the molten steel surface in tundish cover lid layer argon shield, has effectively completely cut off molten steel and air, reduce the degree that molten steel in tundish is oxidized, improves continuous casting process, improve continuous casting billet quality.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model being further described, Fig. 1 is this utility model perspective view.
Detailed description of the invention
A kind of slab CC tundish clad argon-blowing device, as shown in Figure 1, including coordinating on continuous casting production 1, clad 2 is installed, clad 2 arranges stopper hole 4 and orifice 3, clad 2 between stopper hole 4 and orifice 3 arranges two symmetrical through holes, through hole is connected to argon-blowing device, the port that the structure of argon-blowing device is Argon supervisor 6 is connected to transverse pipe 5 and constitutes T-shaped pipe, respectively connected the vertical tube of downward bending on the port at transverse pipe 5 two ends, two vertical tubes are connected with two through holes of clad 2 respectively.
