Spray belt bag

Abstract

The invention relates to a spray belt bag component, which comprises a spray belt bag, a spray nozzle, a graphite strip and a crystallization roller, wherein the spray belt bag is used for accommodating molten metal, the spray nozzle is communicated with the spray belt bag, the molten metal in the spray belt bag is sprayed out through the spray nozzle, the graphite strip is connected with the spray belt bag and is arranged around the spray nozzle, when the spray nozzle sprays the molten metal, the graphite strip prevents the molten metal from being oxidized, and simultaneously, air is prevented from being blown to the molten metal to generate air bubbles, the crystallization roller is arranged under the spray nozzle and the graphite strip, and the molten metal sprayed by the spray nozzle forms amorphous alloy belts on the crystallization roller. The spray belt bag component provided by the embodiment of the invention has the advantages that the graphite strip is arranged around the spray nozzle, the spray nozzle is surrounded by the graphite strip, and the stable environment is created for the molten metal spraying by the spray nozzle, so the air bubble number of the cooling surface is reduced, and the surface toughness of the amorphous alloy belts is improved; and in the high-temperature environment, the graphite strip is oxidized to generate reducing gas so that the molten metal at the melting pool part cannot be oxidized.

Description

technical field [0001] The embodiments of the present invention relate to the field of preparation of amorphous alloy strips, in particular to a spray tape package. Background technique [0002] The traditional method of preparing amorphous thin strips is to smelt the metal into a liquid through an intermediate frequency induction furnace, pour the molten metal into the tundish, pour the bottom into the belt spray bag, and spray the molten metal through the nozzle to the high-speed rotating crystallization roller It is instantly solidified into an amorphous alloy strip with a thickness of 25-30 microns. However, it is very difficult to cast a smooth amorphous alloy strip with traditional equipment, because, on the one hand, during the cooling process, the air will cause air pockets on the cooling surface (the surface where the metal solution contacts the crystallization roller) so that the amorphous alloy strip Defects are generated on the surface, and these defects affect ...

Problems solved by technology

[0004] The object of the present invention is to propose a spray belt package, which aims to solve the problem that the molten pool is exposed to the air during the cooling process, which will cause air pockets on the cooling surface, thereby causing defects on the surface of the amorphous alloy strip. The problem that the molten pool is easily oxidized when exposed to the air
