策が必要である。Glasses having a glass composition that is difficult to be vitrified through stress are vitrified and crushed by pouring them into water and rapidly cooling them. This method is generally called ``suikori'' or ``suigeri.''
However, the particle size of crushed glass is 0.1
It is distributed in the range of ~6■. For example, when pouring molten glass into an aquarium, methods such as applying a water stream or stirring may be used, but the particle size of glass that has been crushed to 21 μm is large (because it is non-uniform, it is difficult to vitrify it sufficiently). Another well-known method for forming glass spheres is to blow molten glass with high-pressure air to crush it and form glass spheres at 14:00, but this method is necessary because it generates dust. .

均一な状態を得ることは１越であった。Glasses that are easily crystallized, that is, those that have materials and compositions that are difficult to vitrify, are not sufficiently vitrified even by the water pulverization and are in a crystalline state or a mixture of vitrified products and crystals.
It will be a consignment. - In order to impart magnetic properties to curvature, vitrification is a necessary condition for glass, but it is impossible to obtain a uniform state of vitrification using conventional methods, that is, water pulverization. Ta.

である。Magnetic glass is required to have strong magnetism and uniform magnetism. Fine magnetic crystals with a uniform particle size are produced in the warehouse and used for the purpose, but the characteristics required for magnetic glass for such purposes are uniform vitrification. , and the particle size must be as small as possible since it will be ground into fine powder in the next step.

Magnetic glass with on-Ba040s composition (2)
It is melted at a high temperature of 1360 to 1500°C from the electric furnace (3). The glass raw material is continuously or intermittently supplied by a water-cooled screier feeder type raw material feeder (4). The molten magnetic glass is placed in a platinum crucible (

に容易に炉から流出させることができる。A platinum nozzle or a refractory nozzle is used for this outflow hole (5). Unlike ordinary glass, magnetic glass has an extremely low viscosity at high temperatures and can be easily flowed out of a furnace like molten metal.

方向へ９０〜１６０００角度、で噴射される。Next, the flow of magnetic glass (6) flowing out of the furnace is heated to a high temperature.
Cold water maintained in a low viscosity state and having a pressure of 6 V or more at room temperature or lower is injected from a nozzle (7) across this flow path to form a jet stream (8). This fountain stream (8) is injected downwardly at an angle of 90 to 120 degrees and upwardly at an angle of 90 to 16,000 degrees with respect to the magnetic glass stream (6).
この噴射角度が特に下方向６ζ対して９０”より大きく
なると、粉砕されたガラスの粒度が粗大化してしまう。If this injection angle is larger than 90'' especially in the downward direction 6ζ, the particle size of the crushed glass will become coarse.
冷水を噴射するノズル（８）は円筒形状が最も効率的で

合致する粒度のものである。The magnetic glass flowing into the fountain stream (8) is pulverized into pieces and at the same time is rapidly cooled and vitrified. This crushed glass is stored in a collection hopper (9) along with water and transported to the next process by a conveyor. The magnetic glass thus obtained is uniformly vitrified and has a particle size that matches the target number.
