本発明は、薄帯の製造方法および製造装置、特に薄帯を
精度よく連続的に製造する場合に有用な製造方法および
その製造菱直に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for manufacturing a thin ribbon, and particularly to a manufacturing method useful for continuously manufacturing a thin ribbon with high precision, and a method for manufacturing the same.
最近、金属溶湯から直接金属薄帯を作成する技術が特に
注目されている。Recently, the technology of directly producing metal ribbons from molten metal has been attracting particular attention.
一つは高速回転する金属ローラー等の表面に落陽を噴出
させ、1び〜1ぴ/secの冷却速度で超急冷して、非
晶質化あるいは微結晶化させた金属合金薄帯を作成する
ものであり、その材料の新しい物性が注目されている。One method is to eject a rising sun onto the surface of a metal roller or the like that rotates at high speed, and then ultra-rapidly cool it at a cooling rate of 1 to 1 pi/sec to create an amorphous or microcrystalline metal alloy ribbon. The new physical properties of this material are attracting attention.
一方、他の一つは溶湯を直接圧延して金属薄板(この場
合、超急冷薄帯に比較してより厚い)に鋳造する方法で
ある。前者の方法は、一般に第1図イ,口に示すような
製造装置を用いて行なわれる。すなわち、加熱用ヒータ
3を埋め込んだ耐熱性の綾湯溜め4に入れた金属溶湯1
を長方形状のノズル口を有するノズル(例えば、幅7仇
岬の金属薄帯を得るのには長辺70肋、短辺0.6肋の

転体5の回転面上に噴出させることにより、金属溶湯を
回転面上で急袷,凝固し、金属薄帯2を製造するもので
あった。On the other hand, the other method is to directly roll the molten metal and cast it into a thin metal sheet (in this case, it is thicker than an ultra-quenched ribbon). The former method is generally carried out using a manufacturing apparatus as shown in FIG. That is, molten metal 1 is placed in a heat-resistant twill tank 4 in which a heating heater 3 is embedded.
A nozzle with a rectangular nozzle opening (for example, to obtain a metal ribbon with a width of 7 mm, use a rectangular/nozzle nozzle with 70 ribs on the long side and 0.6 ribs on the short side). By jetting the molten metal onto the rotating surface of the columnar rotating body 5, the molten metal is rapidly solidified on the rotating surface, and the metal ribbon 2 is manufactured.
しかしながら、これには次のような欠点があった。However, this had the following drawbacks.
‘li 超急冷法を用いて薄帯を製造する場合、溶湯を
正確に供給しないと均一な厚みの最尺物を得ることがで
きない。'li When manufacturing a ribbon using the ultra-quenching method, it is not possible to obtain a thin strip with a uniform thickness unless the molten metal is supplied accurately.
ところがノズル部の温度が溶湯の温度に比較して相当低
い(場合によっては300〜50ぴ0低い)ためノズル
部分で溶湯が冷却され、溶傷粘度の上昇、溶湯の固化,
ノズル口の短辺が1肋以下の狭口ノズルにおいては時に

ル口を通過する溶湯量は大きく変化し、回転する冷却体
への溶湯の供給が不均一となるため均一な厚みの長尺物
を得ることが困難となる。However, since the temperature of the nozzle part is considerably lower than the temperature of the molten metal (in some cases, 300 to 50 points lower), the molten metal is cooled at the nozzle part, resulting in an increase in melt viscosity, solidification of the molten metal, and
In narrow-mouth nozzles in which the short side of the nozzle opening is one rib or less, problems such as nozzle blockage sometimes occur. For this reason, the amount of molten metal passing through the nozzle opening varies greatly, and the supply of molten metal to the rotating cooling body becomes uneven, making it difficult to obtain a long object with a uniform thickness.
【2’溶湯温度が高くなると、ノズル口の構成材料が摩
耗、溶損し、ノズル口の形状が変化しやすくなる。[2' When the temperature of the molten metal becomes high, the constituent materials of the nozzle opening will wear out and melt, making the shape of the nozzle opening more likely to change.
これにより、冷却体に供V給する溶湯量も変化するため

物の麹帯を製造する方法を提供するものである。As a result, the amount of molten metal supplied to the cooling body also changes, making it difficult to obtain a uniform long object. The present invention eliminates such drawbacks, and uses a nozzle opening whose slit width can be changed, and the slit of the nozzle opening is widened only at the start of jetting, and the molten substance is jetted onto the cooling surface of a moving cooling body. The present invention provides a method for manufacturing a long koji belt with a uniform thickness by tying and solidifying the koji belt.

駆動装置11に装着されている。By removing the stopper 8, which is fitted into the hole 4a provided at the bottom of the molten metal reservoir 4, from the hole 4a, the molten metal 1 flows through the hole 4a to the fixed nozzle part 6a made of graphite, and then to the movable nozzle 10 made of graphite. From 80 rpm. p. The liquid is disposed so as to be ejected onto the rotating surface of a cylindrical copper roller 5 with a diameter of 50 m and a width of 15 m, which rotates in the direction of the arrow. Moreover, both 9a and gb are optical detection devices that detect that the molten metal has passed through the movable nozzle 10 and actuate the drive device 11 that moves the movable nozzle 103.10b held by the position fixing device 12. The movable nozzle 10 consists of a concave plate 10a and a rectangular plate 1ob that engages with the concave portion, as shown in the opening of FIG. is installed on.

る。The stopper 8 is removed from the molten metal reservoir 4, and the molten metal 1 obtained by heating and melting Fe8 and 6Si2 (numbers indicate atomic %) at 1,350°C with the heater 3 is guided to the fixed nozzle part 6a, and the nozzle opening 7 is inserted into the two sides. Optical detection devices 9a, 9 detect the passage of the molten metal 1 immediately after it is ejected onto the rotating surface of the copper roller 5 through the movable nozzle 10 adjusted to the ×100 side.
In step b, the drive device 11 is operated to move the plates 10a and 10b to a point where the nozzle opening 7 formed by the plates 10a and 10b is 0.55 mm x 10 mm, and then stopped.

By adjusting, it was possible to obtain an amorphous ribbon having a thickness of 35 m, a width of 100 m, and a length of 123 w. In addition, the ribbon obtained in this way has a thickness of about 2.5 at the beginning and at the end.
The thickness was 35 m±1 Am, and was uniform. This is due to the fact that the ribbon obtained using the conventional manufacturing equipment using a graphite nozzle had a length of approximately 16 mm, so the thickness was uniform except for the beginning and end portions of approximately 3.5 mm each. It was extremely good compared to

It was also greatly improved by about 96%. In addition, various thin strips were manufactured with the short side of the nozzle opening 7 ranging from 1 willow to 0.1 rib.
Good results were obtained in all cases. Next, another embodiment of the present invention will be described with reference to FIG. Figure 3A shows an apparatus for manufacturing a thin ribbon which is another embodiment of the present invention.

耐火性材料であれば良い。Further, a plate 10c made of Si02/ZrQ that engages with the lower end of the fixed nozzle 6b and can be used for fixing the position fixed odor 12.
The plate 10c is attached to a drive device 11 that moves the plate 10c via the plate 10c. By operating the drive device 11 and moving the plate 10c, the width of the gap formed by the fixed nozzle 6b and the plate 10c can be adjusted. A manufacturing apparatus was constructed by arranging the molten metal reservoir having the above-mentioned/slip section in close proximity to the rotating copper loaf, as in the previous embodiment. The thin strip obtained using this manufacturing bag has a thickness of 37 m and 0.0 m.
The yield was about 98% at 8rm. The length of the ribbon was also approximately twice that of the retainer. As an example of the present invention, an example in which the nozzle material is graphite or Z2.Si02 has been described, but any fire-resistant material such as Si3N4, carbon, or alumina carbon may be used.

Furthermore, a method using a double roller type, a belt type, or another type of moving cooling body may be used. As described above, according to the present invention, a molten substance is spouted onto the cooling surface of a moving cooling body by widening the slit in the nozzle opening only at the start of jetting, using a nozzle opening whose slit width is changed, and rapidly cooling the molten substance. By coagulating, it is possible to produce a thin strip of the longest thickness with a uniform thickness and a length of 7 to 1 needle compared to the conventional method.
