The carbon-free brick comprises an overall carbon-free pipe brick (1) and an overall carbon-free seat brick (2), wherein cavities of the overall carbon-free pipe brick (1) and the overall carbon-free seat brick (2) are cylindrical holes; a port of the overall carbon-free pipe brick (1) is connected to a port of the overall carbon-free seat brick (2); clamping parts (3) are arranged at corresponding parts of the ports of the overall carbon-free pipe brick (1) and the overall carbon-free seat brick (2); the overall carbon-free seat brick (2) is the thick arch brick, and the upper surface (201) and the lower surface (202) of the overall carbon-free seat brick (2) are horizontal; the horizontal deflection angles alpha of the cylindrical holes of the overall carbon-free pipe brick (1) and the overall carbon-free seat brick (2) are 10 to 30 degrees. The carbon-free brick is simple in structure, long in service life, convenient to install and high in working efficiency.
Description
Technical field
The utility model belongs to converter taphole refractory part field, relates in particular to a kind of converter taphole without carbon brick.
Background technology
Converter taphole is that molten steel is entered unique passage of ladle by converter.During tapping, bear the friction of high-temperature molten steel, slag and wash away and oxidative attack, cause the tap hole life-span very low, need to constantly repair and change, thereby not only can affect the production cycle, and have influence on steel quality and production stability.
At present, the structure of converter taphole is nearly all to be formed by segmentation brick cup, filler, sectional pipe brick masonry both at home and abroad, particularly the converter tapping port part is laid bricks, often suffer washing away of high temperature melting steel, life-span is very short generally at 40～60 heats, therefore need to during stove labour, repeatedly repair even and change, making it cost increases.In addition, converter taphole adopts the technological line of segmentation brick cup, filler and sectional pipe brick to exist complicated operation, and inefficiency, to the certain restriction of production cycle existence of converter.
The utility model content
The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of simple in structure, long service life, and easy for installation, the converter taphole of high efficiency is without carbon brick.
For solving the problems of the technologies described above, the utility model is to realize like this.
Converter taphole is without carbon brick, and it comprises whole carbon-free pipe brick and whole carbon-free brick cup; The inner chamber of the carbon-free pipe brick of described integral body and whole carbon-free brick cup is cylindrical hole; The port of the carbon-free pipe brick of described integral body and the port of whole carbon-free brick cup join.
As a kind of preferred version, the port of the carbon-free pipe brick of integral body described in the utility model and the port corresponding position of whole carbon-free brick cup are provided with shackle member.
As another kind of preferred version, the carbon-free brick cup of integral body described in the utility model is thick wedge brick, its upper surface and lower surface level.
Further, the level angle a of the carbon-free pipe brick of integral body described in the utility model and whole carbon-free brick cup inner chamber cylindrical hole is 10～30 o.
The utility model is simple in structure, high efficiency.The utility model is the design of docking with whole carbon-free brick cup port by the whole carbon-free pipe brick port of employing, its installation process is convenient, reduced the frequency and labour intensity that tap hole refractory brick is repaired, alleviated the erosion of molten steel high temperature oxidation and mechanical erosion and destroyed, obviously extend work-ing life.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Protection domain of the present utility model not only is confined to the statement of following content.
Fig. 1 is the utility model overall appearance figure.

Fig. 3 is the utility model integral installation figure.
In figure: 1, whole carbon-free pipe brick; 2, whole carbon-free brick cup; 3, shackle member; 201, upper surface; 202, lower surface; 4, tap hole.
Embodiment
As shown in Figures 1 and 2, converter taphole is without carbon brick, and it comprises whole carbon-free pipe brick 1 and whole carbon-free brick cup 2; The carbon-free pipe brick 1 of described integral body is cylindrical hole with the inner chamber of whole carbon-free brick cup 2; The port of the carbon-free pipe brick 1 of described integral body and the port of whole carbon-free brick cup 2 join.
The port of the carbon-free pipe brick 1 of integral body described in the utility model and the port corresponding position of whole carbon-free brick cup 2 are provided with shackle member 3.The port of whole carbon-free pipe brick 1 is the port locking with whole carbon-free brick cup 2 through shackle member 3.
Shown in Figure 2, the carbon-free brick cup 2 of integral body described in the utility model is thick wedge brick, its upper surface 201 and lower surface 202 levels.The carbon-free brick cup 2 of the utility model can form integral body with brick wall layer around it, at stove labour phase, tap hole brick cup difficult drop-off.
Shown in Figure 2, the carbon-free pipe brick 1 of integral body described in the utility model is 15 o with the level angle a of whole carbon-free brick cup 2 inner chamber cylindrical holes.
The utility model converter taphole, without carbon brick, does not ooze steel, the high-temperature behavior excellence, and slag corrosion resistance is good, and carbon containing, can not avoid molten steel recarburization, is particularly suitable for smelting special steel grade, and it is high that it has intensity, antistripping, the characteristics such as long service life.
Be understandably, above about specific descriptions of the present utility model, only for the utility model is described, and not be limited to the described technical scheme of the utility model examples of implementation, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.
