に関するものである。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a single roll device that cools and solidifies molten magnetic metals, alloys, etc. and magnetically orients them in the thickness direction. The present invention relates to a single roll device for cooling a melt that is provided with a magnetic force source and applies a DC magnetic field perpendicularly to the roll surface.

が用いられている。[Conventional technology] It is used to rapidly cool molten metals, alloys, etc., and freeze their structure to produce amorphous (including phase states close to amorphous) ribbons, thin wires, etc. A cooling roll device is used.

成であり、片面冷却方式の単ロール装置と両面冷却方式
の双ロール装置とがある。This type of melt cooling roll device melts raw materials such as metals and alloys in an electric furnace or high-frequency furnace, and then squirts the melt from the tip hole of a crucible using gas pressure, and rotates at high speed. It has a structure in which it is brought into contact with the surface of a roll to solidify, and there are two types: a single-roll device with a single-sided cooling method and a double-roll device with a double-sided cooling method.

。In any case, such a roll device is said to be preferable from a practical point of view because it can form continuous ribbons or thin wires of uniform shape, and large-scale manufacturing devices have also been developed.
［発明が解決しようとする問題点］

。[Problems to be Solved by the Invention] However, the purpose of conventional roll devices for cooling melt was simply to rapidly cool (cool) the melt as it passed through the rolls, regardless of the material. . Therefore, even when a magnetic metal or a magnetic alloy is used as the material, the continuous ribbon obtained is isotropic and has the disadvantage that high magnetic properties cannot be obtained.

制御は極めて面倒となる。If the material is a magnetic material, it is possible to give it magnetic anisotropy by once forming a continuous ribbon and then heat-treating it again while applying a magnetic field. There are holes that crystallize when heated, and the manufacturing equipment is complicated because it requires two steps: amorphous production and heat treatment, and the operations and controls to produce a continuous ribbon with uniform properties are difficult. It becomes extremely troublesome.
本発明の目的は、上記のような従来技術の欠点を解消し

融液冷却用の単ロール装置を提供することにある。The purpose of the present invention is to solve the above-mentioned drawbacks of the prior art, and to achieve melt cooling that not only cools and solidifies the material as it passes through the rolls, but also magnetically aligns the material in the thickness direction at the same time as cooling. The purpose of the present invention is to provide a single roll device for use in manufacturing.

路を具備している融液冷却用の単ロール装置である。[Means for Solving the Problems] The present invention, which can achieve the above objects, includes a single roll having a roll surface that receives the melt and rapidly cools it, and a single roll having a magnetomotive force source that cools the melt. This is a single roll device for cooling melt, which is equipped with a magnetic circuit that applies a DC magnetic field in the radial direction of the roll perpendicular to the roll surface in the vicinity of the spouting part.

ように設置する。As the magnetomotive force source, not only electromagnets but also permanent magnets can be used. Further, if necessary, an annular magnetic body or a permanent magnet is arranged on the inner peripheral side of the roll, so that the roll structure is such that the magnetic field is aligned in the radial direction of the roll. The position where the magnetic field is applied is
It is installed so that it includes a position where the melt cools and passes near the Curie point.

非晶質であっても同様である。Therefore, the molten magnetic metal or alloy ejected onto the roll surface is cooled by the roll, and at the same time, under appropriate conditions, is solidified while being magnetically oriented in the thickness direction by the magnetic field created by the magnetic circuit in a certain direction. . As long as the melt is a magnetic material, the same applies whether the obtained product contains crystalline material or is completely amorphous.

金の連続薄帯を容易に製造することができる。Thereby, a continuous ribbon of magnetic metal or alloy having high magnetic properties can be easily produced.
