A modified continuous casting protection pouring sleeve pipe, protection pouring sleeve pipe life after the improvement improves, reduces the staff and changes the frequency of protection pouring sleeve pipe main part, has reduced personnel's intensity of labour for pouring process molten steel strikes lessly, has reduced oxygenation, nitrogen and inclusion phenomenon of pouring process, helps improving the continuous casting billet quality, guarantees that the middle package liquid level is stable, and life improves, but reduction in production cost brings better use prospect.
Description
Technical Field
The utility model relates to a ferrous metallurgy technical field, in particular to modified continuous casting protection pouring sleeve pipe.
Background
An improved continuous casting protective casting sleeve is a sleeve for reducing the impact of molten steel injection flow in the continuous casting process and stabilizing the liquid level of a tundish impact area, and along with the change of times of technology, the requirements of people on the continuous casting protective casting sleeve are higher and higher.
The existing continuous casting protection casting sleeve has certain defects when in use, firstly, molten steel is poured to flow to have the maximum impact depth, the pouring process has great impact stirring to a tundish impact area molten pool, the operation is not stable, and certain adverse effects are realized.
SUMMERY OF THE UTILITY MODEL
A primary object of the present invention is to provide a casting sleeve for continuous casting, which can effectively solve the problems of the prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a modified continuous casting protection pouring sleeve pipe, includes protection pouring sleeve pipe main part, the upper end outer fixed surface of protection pouring sleeve pipe main part is connected with sleeve pipe head piece, the upper end surface of sleeve pipe head piece is provided with the pouring notch, the internal surface of protection pouring sleeve pipe main part is provided with stabilizes the pouring groove, the both sides surface of protection pouring sleeve pipe main part all is provided with the pouring side opening.
Preferably, the casting slot is located on the inner surface of the upper end of the protective casing body.
Preferably, a tapered groove is formed between the protective pouring sleeve main body and the stable pouring groove, and the outer surface of the lower end of the protective pouring sleeve main body is fixedly connected with the outer surface of the upper end of the stable pouring groove through the tapered groove.
Preferably, the outer surface of the lower end of the main body of the protective pouring sleeve is sealed.
Preferably, the pouring side holes and the bottom surface of the main body of the protective pouring sleeve are obliquely arranged.
Compared with the prior art, the utility model discloses following beneficial effect has: this modified continuous casting protection pouring sleeve pipe, the protection pouring sleeve pipe that has the side opening is changed into to the lower part export with former continuous casting protection pouring sleeve pipe by straight cylinder type, molten steel can not get into the pouring basket perpendicularly during the pouring, but in getting into the pouring basket from the side opening of sleeve pipe both sides, reduce the impact of pouring process molten steel, protection pouring sleeve pipe life after the improvement improves, personnel's intensity of labour has been reduced, pouring process molten steel strikes lessly, the oxygenation of pouring process has been reduced, nitrogen and inclusion phenomenon, help improving the continuous casting billet quality, the pouring basket liquid level is stable, long service life improves, can effectual reduction in production cost, be favorable to people's use, whole modified continuous casting protection pouring sleeve pipe simple structure, high durability and convenient operation, the effect of use is better for traditional mode.

Fig. 2 is a cross-sectional view of an improved continuous casting protective pouring sleeve of the present invention.
In the figure: 1. protecting the casting sleeve main body; 2. a casting notch; 3. a casing head block; 4. pouring side holes; 5. and (5) stabilizing the casting groove.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1-2, an improved continuous casting protective pouring sleeve comprises a protective pouring sleeve main body 1, a sleeve head block 3 is fixedly connected to the outer surface of the upper end of the protective pouring sleeve main body 1, a pouring notch 2 is formed in the outer surface of the upper end of the sleeve head block 3, a stable pouring groove 5 is formed in the inner surface of the protective pouring sleeve main body 1, and pouring side holes 4 are formed in the outer surfaces of the two sides of the protective pouring sleeve main body 1.
Further, a casting notch 2 is formed at an inner surface of an upper end of the protective casting sleeve body 1 so that people can easily pour molten steel into the inside.
Further, a conical groove is formed between the protective pouring sleeve main body 1 and the stable pouring groove 5, the outer surface of the lower end of the protective pouring sleeve main body 1 is fixedly connected with the outer surface of the upper end of the stable pouring groove 5 through the conical groove, the phenomena of oxygenation, nitrogen and impurities in the pouring process are reduced, and the improvement of the quality of a continuous casting billet is facilitated.
Furthermore, the outer surface of the lower end of the casting sleeve main body 1 is protected to be sealed, so that the molten steel is effectively prevented from directly falling, and larger impact is avoided.
Furthermore, the pouring side holes 4 and the bottom surface of the protective pouring sleeve main body 1 are obliquely arranged, so that the molten steel in the stable pouring groove 5 can be ensured to completely flow out, and the residue is reduced.
The utility model discloses theory of operation and use flow: when the protective pouring sleeve is used, the original continuous casting protective pouring sleeve is changed from a straight cylinder type into a protective pouring sleeve with pouring side holes 4 at the lower outlet, molten steel cannot vertically enter a tundish during pouring, but enters the tundish from the pouring side holes 4 at two sides of the sleeve, so that the impact of the molten steel in the pouring process is reduced, the service life of the protective pouring sleeve main body 1 can be effectively prolonged, the working frequency of workers for replacing the protective pouring sleeve main body 1 is reduced, the labor intensity of the workers is reduced, the molten steel impact in the pouring process can be smaller, the phenomena of oxygen increase, nitrogen and impurity inclusion in the pouring process are reduced, the quality of a continuous casting blank can be improved, the stability of the liquid level in the tundish can be ensured, the service life of the protective pouring sleeve is prolonged, the production cost is effectively reduced, and the use.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
