Adopt above -mentioned structure combined type long -life tapping oral siphon brick, have very excellent thermal shock stability and anti erodeing nature of molten steel, after the improvement, reduced the reaming speed of managing the brick hole by a wide margin for tapping time stablizes within the scope of steel factory requirement always, and makes the life of tapping hole lengthen 45~60%, meanwhile, has effectively avoided traditional tapping oral siphon brick afterbody to loose and has flowed the phenomenon.
Description
Technical field
This utility model relates to technical field of refractory materials, in particular to a kind of combined type long-life steel-tapping hole tube brick.
Background technology
Converter is the capital equipment of steel-making at present, and tapping hole is poured into the necessary channel of ladle as molten steel by converter, and its working condition is quite severe, is often subject to molten steel, the friction damage of slag, mechanical erosion destruction, high-temperature slag chemical erosion etc. effect.In use, traditional steel-tapping hole tube brick there will be internal diameter and expands the phenomenon that speed is too fast, this phenomenon can bring following problem to steel mill's steel-making: 1) steel-tapping hole tube brick in use aperture constantly expands, the steel force and velocity of a current must increase, the tapping time shortens therewith, steel mill is in order to ensure to smelt normally rhythm, the tapping time must control within the specific limits, go beyond the scope, steel-tapping hole tube brick must be changed and can be only achieved technological requirement, this is accomplished by increasing hot repair number of times, virtually reduces steelmaking operations rate, adds smelting cost；2) when steel-tapping hole tube brick uses latter stage, its afterbody reaming seriously also results in there is molten steel diffusing phenomenon, so not only makes part molten steel again be oxidized, and reduces recovery rate, and the quality of molten steel can be affected, increase extra smelting cost to techniques such as the refine in downstream, continuous castings.
Summary of the invention
The purpose of this utility model seeks to provide that a kind of flushing resistance is good, internal diameter reaming speed is low, high life, avoid molten steel the combined type long-life steel-tapping hole tube brick of diffusing phenomenon occur.
For achieving the above object, combined type long-life steel-tapping hole tube brick designed by this utility model, including being the pipe brick body section of hollow structure, pipe brick top section and pipe brick end segment, it is characterized in that the top of described pipe brick body section is connected with pipe brick top section and pipe brick end segment respectively through card slot type structure with bottom, and its contact portion is by high-temperature flame-proof glue bond；Described pipe brick top section and pipe brick end segment inwall are also equipped with zirconium ring；
Preferably one:
Described pipe brick body section is the monolithic construction adopting isostatic pressing structure.The curved circulus of top inner wall of described zirconium ring.The height of described pipe brick top section is identical with the height of pipe brick end segment and be H, meets following mathematical relationship: 2/3H≤h≤3/4H between the height h and described height H of described zirconium ring.Described zirconium ring outer wall is inversed taper platform structure, and bottom it, outer diameter D 1 is less than its top outer diameter D2.Described pipe brick top section and pipe brick end segment are mechanical pressing structure.
Preferably two:
Described pipe brick body section is segment type structure, and described segment type structure is mechanical pressing structure.It is connected by card slot type structure between described each articulated structure, and its contact portion is by high-temperature flame-proof glue bond.The height of described pipe brick top section is identical with the height of pipe brick end segment and be H, meets following mathematical relationship: 2/3H≤h≤3/4H between the height h and described height H of described zirconium ring.Described zirconium ring outer wall is inversed taper platform structure, and bottom it, outer diameter D 1 is less than its top outer diameter D2.Described pipe brick top section and pipe brick end segment are mechanical pressing structure.
The utility model has the advantage of: adopt said structure combined type long-life steel-tapping hole tube brick, there is very excellent thermal shock resistance and anti-molten steel erosion, after improvement, considerably reduce the reaming speed of pipe brick endoporus, make the tapping time always stable within the scope that steel mill requires, and make extend 45～60% the service life of tapping hole, meanwhile, effectively prevent tradition steel-tapping hole tube brick afterbody diffusing phenomenon.

Fig. 2 is the structure for amplifying schematic diagram of zirconium ring in Fig. 1.
Fig. 3 is the structural representation of another kind of combined type long-life steel-tapping hole tube brick.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1:
Combined type long-life steel-tapping hole tube brick as shown in Fig. 1～2, including being the pipe brick body section 1 of hollow structure, pipe brick top section 3 and pipe brick end segment 4, the top of pipe brick body section 1 is connected with pipe brick top section 3 and pipe brick end segment 4 respectively through card slot type structure with bottom, and its contact portion is by high-temperature flame-proof glue bond；In the present embodiment, pipe brick body section 1 adopts the monolithic construction of isostatic pressing；Pipe brick top section 3 and pipe brick end segment 4 are mechanical pressing structure.
Pipe brick top section 3 and pipe brick end segment 4 inwall are also equipped with zirconium ring 5, and zirconium ring 5 outer wall is inversed taper platform structure, and bottom it, outer diameter D 1 is less than its top outer diameter D2.The top inner wall of zirconium ring 5 is cambered surface circulus.The height of pipe brick top section 3 is identical with the height of pipe brick end segment 4 and be H, meets following mathematical relationship: 2/3H≤h≤3/4H between the height h and height H of zirconium ring 5.
Embodiment 2:
Another kind of combined type long-life steel-tapping hole tube brick as shown in Figure 3, its population structure is substantially the same manner as Example 1, and simply in the present embodiment, pipe brick body section 1 is in segment type structure, and segment type structure is mechanical pressing structure；It is connected by card slot type structure between each articulated structure, and its contact portion is by high-temperature flame-proof glue bond.
Combined type long-life steel-tapping hole tube brick designed by this utility model adds zirconium ring 5 at pipe brick top section 3 and pipe brick end segment 4 so that it is have very excellent thermal shock resistance and anti-molten steel erosion.Prove through using, considerably reduce the reaming speed of pipe brick endoporus so that the tapping time is always stable within the scope that steel mill requires, and makes improve 50～60% the service life of tapping hole, meanwhile, effectively prevent pipe brick end segment 4 diffusing phenomenon.Used by this utility model, zirconium ring 5 endoporus upper design is arc shape.In use for some time, when this position directly contacts with molten steel, this curved portions potential energy has effectively cushioned the impulsive force of molten steel, it is to avoid the possibility that phase zirconium ring is washed out after a procedure.Meanwhile, zirconium ring 5 design bottom external diameter is less than its top outer diameter so that zirconium ring 5 is fixed by pipe brick end segment 4 well, further avoid the possibility that phase zirconium ring 5 is washed out after a procedure.
