The present invention relates to a heat insulating device of a nozzle to spray molten metal installed in a bottom of a tundish to receive molten metal to prevent a decrease a temperature of a nozzle and to prevent the molten metal from coagulating by improving the heat insulating and reserving properties of the nozzle; thereby preventing a decrease in the temperature of the nozzle for spraying molten metal. The heat insulating device of the nozzle to spray molten metal comprises: a heating pipe arranged on an outer side of the nozzle, applying heat to the nozzle; and a supply part connected to the heating pipe supplying high-temperature heat media inside the heating pipe.

The present invention provides an apparatus to manufacture amorphous materials to minimize an inflow of air flowing with a rotation of a cooling wheel into a nozzle without hindering an overall process flow. The apparatus to manufacture the amorphous materials comprises: a crucible to store a molten steel inside the tundish; the nozzle installed under the tundish outside the tundish to inject the molten steel stored in the crucible; a cooling wheel arranged at a distance from a bottom of the nozzle to rapidly cool the molten steel injected from the nozzle to manufacture a strip; and a blocking part to block an inflow of air flowing through the cooling wheel into the nozzle when the cooling wheel rotates at high speeds. The blocking part comprises a decompression plate arranged at a distance from the nozzle, is extended in an axial direction of the cooling wheel, and is separated from the outer circumference of the cooling wheel at a distance.
