Conventional continuous casting equipment generally uses a mold method, steel belt method, caterpillar method, roll method, or a combination of these methods. Because of the surface contact, there is a significant cooling rate difference between the molten metal contacting area with the metal plate and other areas, and the molten metal contacting area is cooled more rapidly than the other areas. Therefore, the products cast by the continuous casting equipment mentioned above may suffer from segregation, cracks, distortion, etc.
Bubbles are generated, leading to internal defects and surface defects. Conventionally, in order to solve these problems, the cross-sectional area of the casting was enlarged in advance using a casting machine, and then a forging process was performed on the cross-sectional area to produce the desired thin wire.

る。 Furthermore, Japanese Patent Laid-Open No. 134820/1983 discloses an invention in which a metal mesh, perforated plate, or uneven plate is used instead of the metal plate. This invention prevents internal defects in the product by eliminating surface contact with the molten metal using a net or the like and preventing rapid cooling of the molten metal. Moreover, this invention
By using a net, etc. to reduce the contact area with the molten metal and prevent rapid cooling, the molten metal is solidified into a nearly circular cross-section due to the cohesive force based on surface tension, eliminating the need for forging. .
然るに、上記金属板を用いた従来の装置では、
連続鋳造装置に鍛圧加工手段が必要であるから、
高価な鍛圧設備を要すると共に作業工数の増加に
よつて製造コストが著しく高くつくという欠点が
ある。
However, in the conventional device using the metal plate,
Since continuous casting equipment requires forging processing means,
This method has disadvantages in that it requires expensive forging equipment and increases the number of man-hours, which significantly increases manufacturing costs.
また、網等を用いた従来の発明では、上記鍛圧
加工手段は不要とすることができる。しかしなが

隙部位）にかみ込むので、金属線の下部で網目に
対応した微小な凹凸が不可避的に形成され、完全
な断面円形の金属線は得られないという問題があ
る。 Further, in the conventional invention using a net or the like, the forging means described above can be made unnecessary. However, in this invention, part of the molten metal that has flowed down onto the mesh is captured on the material of the mesh, and the other part is caught in the mesh (void area), so that microscopic particles corresponding to the mesh are formed at the bottom of the metal wire. There is a problem in that unevenness is inevitably formed and a metal wire with a perfectly circular cross section cannot be obtained.
更に、溶融金属における網素材に接触した部位

特に、網素材が銅等の金属である場合、網素材に

る金属線の組織は長手方向で均一にはならない。 Furthermore, there is a difference in the cooling rate between the part of the molten metal that comes into contact with the mesh material and the part that is caught in the mesh.
In particular, when the net material is a metal such as copper, the molten metal is rapidly cooled at the portions that come into contact with the net material, causing problems such as local segregation. If the net material is silica wool, etc., rapid cooling may be less likely to occur than in the case of metal, but even in that case, there will be some cooling at the part of the molten metal that comes into contact with the net material and the part that gets caught in the mesh. Due to the difference in speed, the structure of the manufactured metal wire is not uniform in the longitudinal direction.

In order to solve the above-mentioned problems, the continuous casting apparatus for thin wire of the present invention is a continuous casting apparatus for producing fine wire by flowing molten metal from the sprue of a crucible onto the upper surface of a movable metal receiving member. The hot water receiving member is formed into a substantially disk shape and is rotated within the same plane, and the hot water receiving member is formed by adding an inorganic binder to ceramic fibers or mineral fibers and silicic acid powder, and then firing. It is characterized by consisting of

According to the above configuration, the molten metal in the crucible is continuously poured from the sprue onto the upper surface of the metal receiver member, and is continuously cast and solidified on the metal receiver member that is rotated in the same plane. A thin line is formed.

ができる。 This hot water receiving member is made of ceramic fibers or mineral fibers, silicic acid powder, and an inorganic binder, which is molded and then fired, so it has high heat shielding properties and heat resistance. Therefore, the cooling rate of the molten metal that has flowed down to the top surface of the metal receiver is relatively slow, and the heat dissipation is almost even between the bottom surface that contacts the metal receiver and other parts, so that solidification is slow. Internal defects and surface defects can be completely prevented.

略断面円形状となることができる。 In addition, this hot water receiving member contains ceramic fiber or mineral fiber, which is a material with a weak affinity for molten metal, and silicic acid powder (diatomaceous earth silica, etc.), and is fired so that the surface is almost smooth. molten metal, it is possible to reduce wetting of the molten metal. Therefore, the molten metal exhibits sufficient cohesive force due to surface tension on the receiving member, and can have a more perfect substantially circular cross-sectional shape.

is attached. This hot water receiving disk 3 is made by mixing three types of materials: heat-resistant reinforcing fibers such as ceramic fibers or mineral fibers, silicic acid powder such as diatomaceous earth silica, and an inorganic binder, forming the mixture into a disk shape, and then firing it. For example, by heating at about 1000°C, it has heat resistance and heat shielding properties.

Furthermore, the hot water receiving disk 3 may be manufactured by adding an inorganic binder to calcium silicate produced from silicic acid powder and lime asbestos fibers and firing the mixture. Note that the above-mentioned fibers are materials for obtaining strength, heat shielding properties, and heat resistance, and the diameter of the fibers is, for example, about 2 to 6 μm, although it depends on the type. Further, the above-mentioned silicic acid powder is used to obtain heat shielding properties and heat resistance.

等に応じて設定される。 8 is disposed below the crucible 4, and
This is a sprue that receives molten metal flowing down from the pipe. The sprue 9 of the sprue 8 is provided along the upper surface of the saucer disc 3 at intervals, and is formed to have as small a diameter as possible depending on the flowability of the molten metal. Further, the crucible 4 is controlled so that a constant amount of molten metal always remains in the sprue 8 by opening and closing the hole 5 with the stopper rod 6. Therefore, a constant flow rate of molten metal is always supplied from the spout 9 of the sprue 8. The distance between the spout 9 and the tap belt 3 is set depending on the diameter of the fine wire to be cast.

Operate the motor to rotate the turntable 2,
is rotated at a steady speed in the same plane.

線材の形成が可能である。 Next, the stopper rod 6 of the crucible 4 is pulled up and the molten metal flows down into the sprue 8 through the feeding hole 5, and the molten metal filling the sprue 8 flows through the pouring spout 9 at its tip. Since the molten metal is continuously poured onto the receiving disk 3 in a fixed amount, the continuously poured molten metal is continuously cast and solidified on the rotating receiving disk 3. A continuous wire rod 10 is formed according to the shape of the spout 9 of the sprue 8. This wire rod 10 solidifies gradually and uniformly on the hot water receiving disk 3 due to its heat shielding properties, so that no internal defects or surface defects occur. In addition, since the molten metal wets less on the molten metal receiving disk 3 made of a material with poor affinity with the molten metal, the cohesive force based on surface tension is fully exerted, and a wire rod with a substantially perfect circular cross section can be obtained. It will be done. The wire diameter of the fine wire 10 is determined mainly by the opening area of the sprue 9 of the sprue 8 and the rotational speed of the saucer disk 3, and is influenced by the casting temperature, the surface tension of the molten metal, and the like. The diameter of the thin wire 10 decreases in proportion to the running speed of the hot water receiving disk 3, and the higher the melting point of the metal, the greater the surface tension in the molten state, so it is possible to form a wire rod with a perfectly circular cross section.
尚、前記湯口８の注湯口９の開口断面形状につ

面円形の線材が形成される。 The cross-sectional shape of the opening of the pouring spout 9 of the sprue 8 is hardly affected by the spout shape because the cross-sectional shape of the wire is formed into a circular shape by surface tension. Even if the wire rod is shaped like a section, a wire rod having a circular cross section is formed.
尚、本実施例では、全体に湾曲した細線１０が
形成されるが、図示しないガイドローラ等によつ
て任意に直線的に矯正し得るものである。 In this embodiment, the thin wire 10 is entirely curved, but it can be straightened arbitrarily into a straight line using a guide roller (not shown) or the like.

The surface conditions will be compared and explained.

る。 According to conventional casting equipment, the poured molten metal comes into contact with the metal plate, and the metal plate has almost no heat shielding properties, so the heat of the molten metal is absorbed by the metal plate and rapidly Cool and solidify. Therefore,
As shown in Figure 3, the columnar crystals grow larger toward the center, and the molten metal contacts the metal plate A at a
A significant temperature difference instantaneously occurs between the mold and the non-contact area b, which causes segregation, cracks, distortion, bubbles, etc. in the solidified state, and also creates gaps between the mold surface and the solidified mass. In such cases, sweating may occur, leading to internal and surface defects in the product. Such defects inevitably occur when molten metal is quenched from one direction to continuously cast the material.

Since the hot water receiving disk 3 itself has a heat shielding property, as shown in Fig. 2, although the columnar crystals grow toward the center, they are not very large, which is compatible with the cooling effect in the non-contact area b of the molten metal. As a result, the molten metal solidifies uniformly at a relatively slow cooling rate, with almost no temperature difference between the contact area a and the non-contact area b of the molten metal on the surface of the molten metal receiving disk 3. It does not cause segregation, cracks, distortion, bubbles, etc.
That is, since the heat of the molten metal is uniformly dissipated from the entire circumferential surface, a uniform fine structure can be obtained.

As described above, the thin wire continuous casting device of the present invention has the following features:
The hot water receiving member is formed into a substantially disk shape and is driven to rotate within the same plane, and the hot water receiving member is formed by adding an inorganic binder to ceramic fibers or mineral fibers and silicic acid powder, and then firing it. The structure is as follows.

るといつた効果を奏する。 As a result, since the molten metal receiving member has heat shielding properties, only the portion of the molten metal that comes into contact with the molten metal receiving member is not rapidly cooled, and the heat of the molten metal is distributed uniformly from the entire circumferential surface. , because it is gradually dissipated, it is possible to obtain fine wires without internal defects or surface defects. In addition, this method allows the molten metal to be cooled and cast in an as-cast state without the need for a forging process, which reduces the manufacturing process and eliminates the need for advanced measurement and control technology. This has the advantage that the device can be significantly simplified.

併せて奏する。 Furthermore, the receiving member is made of a material with low wettability to molten metal, and the surface is almost smooth by molding ceramic fibers or mineral fibers and silicic acid powder with an inorganic binder and then firing them. Therefore, unlike when using a net-shaped metal receiving member, the molten metal is not captured by the receiving member, and the cohesive force based on the surface tension of the molten metal is fully exerted. It also has the effect of being able to obtain a wire rod with a perfectly circular cross section.
