Description of the Related Art Recently, in continuous casting in the steel industry, a method of directly producing a thin steel sheet having a thickness of several tens of millimeters or less, which is close to the thickness of a final product, by a continuous casting method has been tried. According to this method, since it is possible to omit the conventional multi-step rolling process, it is possible to omit the process and equipment, and it is also possible to omit the heat treatment between each process, and an energy saving effect can be expected. There is a long-awaited industrialization.

特徴を有するものである。According to this type of twin belt system, there is no opening between the blocks at the upper end of the mold unlike the so-called block type continuous casting system disclosed in Japanese Patent Laid-Open No. 62-57744. Therefore, since it is not necessary to insert the nozzle into the deep part of the mold, the mold thickness can be made thin, and continuous casting of a thin steel plate is easy.

であった。However, the twin belt system described above has the following problems. That is, as shown in Japanese Patent Publication No. 57-61502, the belt is deformed. The deformation of the belt is such that the thin steel plate is cast at the central portion in the width direction of the belt, so that the thermal expansion of the central portion in the width direction of the belt is large, resulting in the deformation of the belt.
When the belt is deformed, not only it becomes difficult to cast a thin steel plate having a uniform thickness, but also the life of the belt is shortened. Therefore, in order to solve the above problems, the belt is preheated as shown in Japanese Patent Publication No. 57-61502, or as disclosed in Japanese Patent Laid-Open No. 62-77161. Like coating the belt,
Or, as shown in Japanese Utility Model Publication No. 59-58550,
It is necessary to reduce the temperature difference in the width direction of the belt by heating both ends in the width direction of the belt, or to adopt various additional methods and incidental equipment, but the effect is insufficient, and the manufacturing cost and equipment are also added. The high cost was unavoidable.

Moreover, there is a risk of steam explosion if the belt is melted or worn. The present invention provides a continuous casting apparatus for thin plates which does not have the above-mentioned problems and which can change the plate thickness and the plate width.

ある。The first feature of the present invention resides in the special structure of the endless belt for forming the long side of the mold, which is completely different from the conventional twin belt system or block system. That is, as a component of the endless belt, a flexible metal strip plate adopted as a conventional twin belt type endless metal belt is used, for example, with a plate thickness of 0.5 to 5 mm and a plate width of about 1 to 10 mm. A rectangular thin metal plate is used. In the present invention, a large number of the rectangular thin metal plates are provided on one surface of the flexible metal strip in the longitudinal direction of the strip at an evenly dense pitch, and the long side one end face side of each rectangular thin metal plate is the strip plate. It is fastened in the width direction and erected at an equal angle, and the flexible metal strips are connected to the inside to form an endless shape. This is laid over at least a pair of guide rolls to form a thin metal plate standing endless strip for forming the long side of the mold, and one set of these is opposed to form a thin mold between the facing surfaces.

能となるものである。Therefore, according to the above-mentioned endless strip of the thin metal plate for forming the long side of the mold of the present invention, the strip plate thickness, the thickness of the thin metal plate, the width, the standing pitch, the guide roll diameter, etc. are selected. By appropriately selecting these, even though the rectangular thin metal plate is erected on the flexible metal strip, the gap between the thin metal plates when the guide roll is rotated is substantially reduced. It is possible to make a minute gap (for example, 0.1 mm or less) in which molten steel does not enter. As a result, unlike the conventional block method, it is not necessary to insert the injection nozzle into the deep part of the mold formed by the straight parallel parts, and therefore the thickness of the mold can be arbitrarily reduced without being restricted by the injection nozzle. Therefore, the continuous casting of thin steel sheets can be easily performed as in the conventional twin belt method.

ある。Moreover, the thin metal plate standing endless strip for forming the long side of the mold according to the present invention has little thermal deformation. That is, the central part in the width direction of the thin metal plate standing endless strip for forming the long side of the mold is heated to a high temperature by casting, but the endless strip standing for the thin metal plate for forming the long side of the mold is a flexible metal strip. Since it is composed of a number of thin metal plates that are erected on one side of the plate at an equal density pitch, the thin metal plate for forming the long side of the mold is usually installed at the center of the back surface of an endless flexible metal strip. By cooling with the cooling means, it is possible to prevent the widthwise deformation of the standing endless strip of the thin metal plate for forming the long side of the mold. Further, the thermal expansion of the thin metal plate in the plate thickness direction can be effectively absorbed by the small gap between the facing surfaces of the thin metal plate that is erected by appropriately selecting the standing pitch of the thin metal plate. It is possible. Therefore, the thin metal plate for forming the long side of the mold of the present invention has a feature that thermal deformation of the standing endless strip is smaller than that of the conventional twin belt system, and is a thin steel plate that is stable for a long time and has excellent dimensional accuracy. Is obtained.

著しく長くなるものである。The thin metal plate standing endless strip for forming the long side of the mold of the present invention is smoothly wound by the guide rolls.
A thin metal plate with a width of about 1 to 10 mm can be used to form a thick metal plate for forming a long side of a thick mold, so that an endless strip can be constructed. It will be extremely long.

る。A second feature of the present invention is that a thin metal plate for forming a long side of a mold has a groove portion having a plate width and a plate thickness on one side of a flexible metal strip plate having substantially the same structure as the standing endless strip. A plurality of thin metal plates provided on one end surface of the rectangular thin metal plate at equal pitches in the longitudinal direction of the strip at the groove bottom surface side of each thin metal plate in the strip width direction and fixed at equal angles. The endless strip of the thin metal plate for forming the short side of the mold is made endless by connecting the flexible metal strip to the inside of the endless strip of the thin metal plate for forming the long side of the mold. It is wound around both ends and positioned on both sides of the endless strips of standing thin metal plates for forming long sides of the mold which face each other. Therefore, the change of the interval between the endless strips of the thin metal plates for forming the long sides of both molds does not hinder the endless strips of the thin metal plates for forming the short sides of the mold, and the intervals can be arbitrarily changed. The thickness of thin steel plate can be changed.

Move one or both of the endless strips standing on the thin metal plate for forming the short side of the mold wound around the strip appropriately in the axial direction of the guide roll (width direction of the endless strip standing on the thin metal plate for forming the long side of the mold).
