From (3) to (3), the operating surface side lining of the bottom 3- (4) is made of an irregular refractory, and the operating surface side lining 4 of the side wall is constructed of brick. That is, until the life of the lining 4 on the working surface of the side wall portion constructed of the brick is completed, the drawn portion 3- (3) constructed of the refractory material is used.
Conventionally, it has been conventionally attempted to reduce the total cost of refractories by replenishing and repairing the lining of the working surface side of the bottom 3- (4) and repeatedly using it.

箇所の修復を行うことができる。During the processing of the residual metal 8 after the completion of the casting, the residual metal 8 may be caught by the dent-shaped worn portion, making it difficult to remove the metal. At this point, as shown in FIG. 2 (b), the core frame 6- (2) for irregular-shaped refractory construction is installed again, and the irregular-shaped refractory is added and repaired, thereby repairing a locally worn portion. be able to.
【０００９】しかしながら、この従来の方法には、以下
に示すような問題点があった。[0009] However, this conventional method has the following problems.

In the conventional embodiment, the refractory 3 on the working surface side of (4) is added and repaired at every 200 charge casting in the conventional embodiment. However, in order to improve the adhesion between the new and old layers, the slag or the deteriorated layer of the old layer is attached in advance. It was necessary to dismantle the surface and dismantle it with a hand breaker or a dismantling machine that can be operated remotely.

(3) and irregular shaped refractory 3 on the working surface side of the bottom 3- (4)
Sintering proceeds due to preheating before casting and heat received from molten steel during casting, and has a high strength that cannot be easily dismantled. For this reason, the time required to carry out the hanging of the surface required about five times as long as the time required for the conventional brick construction.

享受できないという問題もあった。Further, as described above, since the amorphous refractory 3 on the operating surface side of the drawn portion 3- (3) and the bottom portion 3- (4) has been advanced in sintering, only the adhered slag and altered layer on the surface are removed. Even if it is attempted to remove, it is inevitable that cracks extend to a deep part due to vibration during disassembly. For this reason, the final residual amount is about 1 compared with the time of new construction as shown in FIG.
There was also a problem that the merits of replenishment and repair could not be sufficiently enjoyed.

After curing, the core metal frame 6- (2) for the second-layer working surface side irregular-shaped refractory construction was removed. Thereafter, as the side wall operating surface side lining 4, a medium alumina brick having a thickness of 150 mm was applied, and then a surface coating material 5 was sprayed and applied to complete the final construction as shown in FIG.

％以上とした。The reason why the medium-alumina brick and the irregular-shaped refractory are used as the refractory for the working surface will be described below. When a magnesia-based material is used for the surface coating material 5, the silica content of the operating surface side refractory material needs to be 40% or less to prevent seizure between the operating surface side refractory material and the surface coating material 5. It is. As the refractory on the operating surface side of the tundish, it is common to use an alumina-silica refractory for reasons of durability and cost.

The dent-like wear depth became 70 mm or more, and when the residual metal was pushed down and removed, the clogging became remarkable.

せることができた。At this time, in order to replenish and repair the surface, the surface was suspended with a remotely controllable demolition machine, and only the irregular-shaped refractory 3- (2) on the second-layer working surface side had an edge 7 , And could be removed. This required time was about 2 hours, and was able to be shortened to about 1/5 as compared with the disassembly time of the conventional method disclosed in Japanese Utility Model Laid-Open No. 5-44359.

Irregular refractories were constructed. The construction amount at this time was 2 tons, which was 2/5 of the total amount of 3 tons of the first-layer working surface side irregular-shaped refractory 3- (1) and 5 tons.

It was discovered that sintering progressed to the back of the shaped refractory 3- (1), and countless cracks were generated. further,
Since the wear of the lining 4 on the side wall portion operating surface side also gradually progresses and the remaining thickness is less than half that of the newly constructed building, the first layer operating surface side irregular shaped refractory 3- (1) , And the brick of the lining 4 on the working surface of the side wall were also dismantled and newly constructed.

Was as small as about 1/3 to 1/4, but by the present invention, the remaining weight of the old material could be reliably increased to 3/5 or more. In addition, the time required for disassembly at this time could be reduced to about 1/5 as compared with the conventional method.

In some cases, the slack was not able to continue to be used after 200 charges. However, according to the present invention, the side wall working surface side lining 4 is almost surely continued to about 1000 charges until the good life of the lining 4 is completed. Can now be used.
