Description
Technical field
The utility model belongs to the big jacket tube sealing device of steel plant continuous casting, especially a kind of big packet of continuous casting conveniently taken
Sleeve pipe sealing device.
Background technique
Molding casting of the casing for steel stream between Con casting ladle and tundish, steel stream in protection sleeve pipe internal flow,
It can prevent pouring molten steel process from absorbing oxygen, nitrogen etc. from surrounding air, to reduce or prevent secondary oxidation.Casing is through quiet
Molded aluminum-carbon refractory material protection pipe, product have many advantages, such as heat shock resistance, anti-etch.
The big canning tube top that original uses uses bell shape, and horn mouth is inserted in ladle nozzle when use, due to loudspeaker
Between mouth and ladle nozzle there are gap, casting process can suck air from this gap, therefore be easy to cause molten steel oxygenation, nitrogen
Deng, cause secondary oxidation of steel, make inclusion content in melting steel content increase, be unfavorable for continuous casting process quality control.
Main problem existing for traditional big canning tube is as follows:
1, casting process is easy to produce secondary oxidation, causes molten steel oxygenation, nitrogen etc., and is easy steel slag being involved in molten steel
In, it causes inclusion content to increase, is unfavorable for continuous casting billet quality control.
2, molten steel beam has great impact and aggressivity, and casting process there is greatly impact to stir casing bowl portion
It is dynamic, it causes refractory material to corrode in advance, influences service life, cause the resistance to material usage amount of continuous casting process to increase, influence to produce
Cost.
3, due to the percussion of beam, casing use process is easily caused to be broken, influences surrounding people's operation, is unfavorable for
Safety and stability operation.
Utility model content
The purpose of this utility model is to provide a kind of big jacket tube sealing device of continuous casting conveniently taken, structure is closed
Reason, conveniently takes, and can reduce continuous casting process molten steel beam washing away and corroding to casing bowl portion, improves casing and uses the longevity
Life guarantees safety operation, can prevent the oxygenation of pouring molten steel process, nitrogen, reduces secondary oxidation, controls the amount of inclusions, improves
The quality of continuous cast products.
Purpose of the utility model is realized as follows: a kind of big jacket tube sealing device of continuous casting conveniently taken, including
The ladle nozzle of Con casting ladle setting, the upper end of the big canning tube of continuous casting are arranged the casing seat of horn-like inner wall, ladle nozzle with
The casing seat of the big canning tube upper end of continuous casting matches, and peace is cooperated between ladle nozzle and the casing seat inner wall of the big canning tube of continuous casting
It is filled with fire resistant seal tapered sleeve, handle is set in the upper end of fire resistant seal tapered sleeve, takes the handle of clamp Yu fire resistant seal tapered sleeve
It matches, fire resistant seal tapered sleeve is matched with the horn-like inner wall of the big canning tube casing seat of continuous casting, and is higher by 20- than casing seat
40mm, fire resistant seal tapered sleeve 3 with a thickness of 2-6mm.
Main improvement content is as follows:
1, according to the shape in casing bowl portion, corundum based refractory materials is added using refractory fibre and make gasket, were poured
Gasket is first mounted on the bowl portion of casing by journey, is then connected again with ladle nozzle, using gasket sealing function, is prevented molten steel
Casting process sucks air, prevents secondary oxidation of steel.
Main improvement effect:
1, since the sealing function of Novel sealing cushion, continuous casting process sucking air phenomenon are greatly improved, two are alleviated
Secondary oxidation, molten steel nitrogen increased amount can control within 5ppm, be conducive to continuous casting billet quality control.
2, since molten steel and gasket directly contact, molten steel does not contact directly with casing bowl portion refractory material, therefore can be with
Mitigate the erosion to refractory material and wash away, refractory material service life can be improved, reduce casing usage quantity, reduces steel-making
Production cost.
3, the phenomenon that can eliminating the fracture of casing use process, stable operation can improve execute-in-place condition, be conducive to
Safety operation.
4, it conveniently takes, using clamp-replacing gasket, prevents personnel from scalding, guarantee operator's safety.
The utility model is structurally reasonable, conveniently takes, and reduces continuous casting process molten steel beam and rushes to casing bowl portion
Brush and erosion, improve Service Life of Casing, ensure that safety operation, it is therefore prevented that the oxygenation of pouring molten steel process, nitrogen are reduced secondary
Oxidation controls the amount of inclusions, improves the quality of continuous cast products.
Detailed description of the invention
The utility model is further described below in conjunction with attached drawing, Fig. 1 is the utility model use state structure
Schematic diagram, Fig. 2 are fire resistant seal tapered sleeve structural schematic diagram.
Specific embodiment
A kind of big jacket tube sealing device of continuous casting conveniently taken, as shown in Figure 1 and Figure 2, the steel including Con casting ladle setting
Water-coating port, the upper end of the big canning tube 1 of continuous casting are arranged the casing seat 2 of horn-like inner wall, on ladle nozzle and the big canning tube 1 of continuous casting
The casing seat 2 at end matches, and is coupled fire resistant seal between ladle nozzle and the casing seat inner wall of the big canning tube 1 of continuous casting
Handle 4 is arranged in the upper end of fire resistant seal tapered sleeve 3 in tapered sleeve 3, takes clamp 5 and matches with the handle 4 of fire resistant seal tapered sleeve 3,
Fire resistant seal tapered sleeve 3 is matched with the horn-like inner wall of the big canning tube casing seat 2 of continuous casting, and is higher by 20- than casing seat 2
40mm, fire resistant seal tapered sleeve 3 with a thickness of 2-6mm.Fire resistant seal tapered sleeve 3 is by the refractory fibre structure with corundum based refractory materials
At.
