Conventionally, thin wires or ribbons of amorphous alloys or microcrystalline alloys have been produced by rapidly cooling an alloy prepared to a predetermined composition from a molten state. The nozzle that injects the alloy toward the cooling drum and cooling liquid used as a quenching device is made of heat-resistant ceramics with a melting point of 1500℃ or higher, such as alumina, zirconia, silicon nitride, and silicon carbide.

によつて形成されている。 Such conventional nozzles include those equipped with an injection hole H at the tip of the nozzle body N and an introduction part D for molten metal communicating with the injection hole H, as illustrated in FIG. As shown in FIG. 1, a nozzle body n has a slit-shaped injection hole h at its tip, and a molten metal introduction part d communicating with the injection hole h is used. The introduction portions D and d communicating with the injection holes H and h are formed with large diameter spaces in order to smoothly and stably guide the molten metal from the injection holes H and h.

However, in the above-mentioned nozzles N and n, when the molten metal passes through the introduction parts D and d, the pressure applied to the molten metal (molten metal), the viscosity of the molten metal itself, or the temperature of the molten metal are controlled to optimal values. However, it is extremely difficult to maintain these pressures and temperatures at optimum values, and as a result, turbulence occurs in the molten metal injected from the injection holes H, and the injection flow lacks stability. The fine wire obtained from this process has variations in wire diameter and kinks in the wire. Furthermore, when a thin ribbon is ejected from a slit-shaped injection hole h, there may be problems such as variations in the thickness of the manufactured ribbon or, in severe cases, the ribbon may be split. However, the performance of the thin ribbon was significantly deteriorated and the performance of the thin ribbon became non-uniform.

It is desirable that the porous member T is adhesively fixed to the nozzle body using a suitable adhesive or the like.

Even the material has a circular cross section,
A honeycomb structure is used in which a large number of triangular, hexagonal, etc. through holes t are arranged in the longitudinal direction. In this case, for the honeycomb structure, the optimum shape of the through holes t, i.e., the pore diameter, pore distribution, etc., are determined depending on the type of molten metal to be passed through, temperature, etc., and according to experiments, molten aluminum (700-750℃) Then 50-300 cells/
