ようにした加熱鋳型式連続鋳造装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a continuous casting device using a heated mold, and more particularly, the present invention relates to a continuous casting device using a heated mold, and more specifically, the ingot that comes out of the heated mold has a uniform cross-sectional shape with a smooth and beautiful surface. The present invention relates to a heated mold type continuous casting device that exhibits the following properties.

In conventional general continuous metal casting equipment,
This has been done by using a hollow cooling mold, supplying molten metal from one end of the mold, solidifying the molten metal in contact with the inner wall of the mold, and continuously drawing it out as an ingot from the other end. However, when this device is used, a solidified shell of the ingot is formed in the deep part of the mold, so when the ingot is pulled out from the mold, the friction between the inner wall of the mold and the surface of the ingot causes scratches and cracks on the surface of the ingot. The disadvantage was that surface defects such as these were likely to occur. Therefore, conventionally, when subjecting such an ingot to plastic working such as rolling or forging,
The surface of the ingot had to be ground or scratched beforehand. Especially when surface cracks are deep,
It was impossible to subject the ingot to plastic working, and the ingot became a defective product.

鋳塊を得ることに成功した（特許第1049146号）。 One of the inventors of the present invention previously developed a continuous casting method using a heated mold in order to improve the above-mentioned drawbacks of this conventional general continuous casting method. This continuous casting method prevents the formation of a solidified shell along the side walls inside the mold by heating and maintaining the temperature of the inner wall of the mold at a temperature higher than the solidification temperature of the cast metal. Casting is performed by allowing the solidification of the cast metal to begin as a result of cooling, and through this process, it was possible to obtain a smooth and beautiful ingot with no surface defects (Patent No. 1049146).
しかしながら、この特許第1049146号の連続鋳

However, even with the continuous casting method of this patent No. 1049146, irregular uneven patterns may be formed on the surface of the ingot, cracks may occur, or breakout of the molten metal may occur.
It has been difficult to consistently obtain ingots with smooth and beautiful surfaces over a long period of time.

ずかしい。更に、鋳塊の不規則な振動や揺れが著
しく大きい場合は、溶湯が鋳型からブレークアウ
トする危険性すら生じる可能性がある。 According to the research conducted by the present inventors, the biggest cause of this is the vibration that occurs when the ingot comes into contact with the coolant, and the vibration that occurs when the ingot is pulled out of the mold using pinch rolls. It has been found that this is because the solidification of the unsolidified molten metal on the surface of the ingot directly outside the mold outlet is greatly affected. The effect of such irregular vibrations and shaking of the ingot is more likely to occur as the casting speed increases, especially when the ingot is thin plate-shaped or thin wire. It is difficult to obtain plates and wires of different thicknesses and diameters. Furthermore, if the irregular vibrations or shaking of the ingot are extremely large, there is a possibility that the molten metal may even break out from the mold.

ていることが望ましい。 FIG. 1 is a longitudinal sectional front view of the main part showing the case where the present invention is applied to a downward type continuous casting apparatus for obtaining a rod-shaped metal molded body. A heating mold is provided so as to open at the bottom to constitute a molten metal inlet, and the opening at the lower end is hollow with an arbitrary cross-sectional shape constituting an ingot outlet. In heating mold 1,
A heating element 2 made of an electrical resistance heating wire such as a nichrome wire or a kanthal wire is built-in. The heating element 2 is for heating the inner wall of the heating mold 1 to a temperature higher than the solidification temperature of the molten metal 3. In this configuration example, the heating mold 1 has the heating element 2 built-in, but it is an external heating method that heats from the outside. Of course, a heated mold may also be used. On the exit side of the heating mold 1, there is a cooling device 5, which includes a sprayer, etc., which injects cooling water or cooling air into the ingot 4 obtained by drawing it out from the heating mold 1, and cools the ingot 4. Pinch rolls 6 for drawers are arranged. A hollow guide mold 7 has one end connected to the outlet end of the heating mold 1, and is used to prevent the ingot 4 from vibrating at the mold outlet. The guide mold 7 is made of a hard refractory material such as silicon carbide, zirconia, or fused alumina that will not be worn out by friction when the ingot 4 is pulled out, so that it is difficult to cause scratches on the surface of the ingot. A refractory type with a mirror-finished inner wall surface, or a soft material such as graphite or boron nitride that wears away due to friction when the ingot is pulled out and does not easily cause scratches on the ingot surface. has been done. If a hard refractory having a rough inner wall is used as a guide mold, the ingot will be scratched. The guide mold 7 has an inner wall below the solidification temperature of the molten metal 3,
In order to prevent the formation of crystals on the inner wall surface thereof, it is desirable that the temperature is maintained at a temperature higher than that of the ingot 4 or the ingot dummy.

In this third embodiment, a heating mold 21 disposed substantially vertically has a heating element 22 built therein. In this case, heating mold 2
1 is mostly immersed in the molten metal 23, so
Since the inner wall surface of the immersed part of the heating mold 21 is heated by the heat held by the molten metal 23, current is supplied to the heating element 22 only when the inner wall surface is not heated above the solidification temperature of the molten metal 23. Therefore, it is only necessary to heat it to a predetermined temperature. Note that if the temperature of the molten metal into which the heating mold 21 is immersed is set to a sufficiently high temperature higher than the solidification temperature, the built-in heating element 22 may be omitted. The upper outlet end of the heating mold 21 located above the hot water level constitutes a guide mold 25 . That is, in the first and second embodiments described above, the guide molds 7 and 17 are provided separately from the heating molds 1 and 11, and are attached to the outlet end of the heating mold, but in the third embodiment, A guide mold 25 is integrally formed at the outlet end of the heating mold 21. As described above, the guide mold only needs to have a temperature distribution that is below the solidification temperature of the molten metal 23, so a heating element 22 is provided in the portion corresponding to the guide mold 25.
In order to obtain a predetermined temperature distribution, a predetermined temperature distribution is obtained. A cooling device 26 for the ingot 24 from which water or air is sprayed is located above the guide mold 25 via a shielding plate 28, similar to the cooling device 5 of the first embodiment. A pinch roll 27 similar to the pinch roll 6 of the first embodiment described above is located above the cooling device 26, and the cooled ingot 24 is pulled out. The temperature of the molten metal 23, the amount of coolant such as water and air supplied from the cooling device 26, and the amount of ingot lifting so that the tip of the ingot 24 solidifies below the surface of the holding furnace holding the molten metal. By adjusting the rotational speed of the pinch rolls 27, etc., the heating mold 2 of the ingot is heated.
A smooth and beautiful ingot without unevenness on the casting surface caused by vibration at the outlet end of step 1 can be obtained.

As described above, the heating mold type continuous casting apparatus of the present invention has a simple structure in which a hollow guide mold is provided at the outlet end of the heating mold to prevent vibration of the ingot. It is possible to continuously obtain smooth and beautiful cast ingots that always stably have a uniform cross-sectional shape without being affected by vibrations caused by pinch rolls or the like. If the surface of the ingot obtained by continuous casting is smooth and beautiful, it can be used directly as products such as wires, plates, rods, and tubes without surface finishing. Furthermore, the ability to cast castings with complex cross-sectional shapes, such as gears and turbine blades, by continuous casting, and then cut them into appropriate lengths and use them directly as products, eliminates the finishing process and saves energy. This invention is extremely desirable in terms of economy, and is extremely useful for continuous casting of such smooth and beautiful ingots.

The temperature distribution is such that only the exit end of the heated mold, which is maintained above the temperature and prevented from solidifying the surface layer of the ingot on the inner wall surface, is below the solidification temperature of the molten metal. By controlling the heating of the heating mold, the outlet end of the heating mold may be integrally configured as a guide mold.
