Abstract

The invention provides a rapid solidification metal strip production device and a method thereof. Mother alloy is smelted in a vacuum melting furnace, strip pressure spraying is carried out through a spray nozzle, strip spraying atmosphere protection is carried out at the spray nozzle, and a middle liquid-holding crucible is arranged in a jetting ladle and can compensate alloy solutions for a spray nozzle ladle crucible. Mother alloy smelting is finished in the vacuum melting furnace firstly, then the alloy solutions are poured into the liquid-holding crucible in the jetting ladle, and a gate valve between the vacuum melting furnace and a spray nozzle ladle is shut off. Then the mother alloy solutions are compensated for the spray nozzle ladle crucible from the middle liquid-holding crucible, protection gases are injected into the spray nozzle ladle, pressurization is carried out, and under the action of pressure, and the metal solutions are sprayed out from spray nozzle seams in the spray nozzle ladle to solidify so as to form a strip on the surface of a water-cooling copper roller rotating at a high speed. Protection is carried out through protective atmosphere at a smelting pit area where solidification occurs. The device has the advantages of being anti-oxidation and high in yield, products have high performance and the yield is much higher than that of a traditional full-vacuum strip casting mode.

Description

technical field [0001] The invention relates to the technical field of metal rapid solidification, and belongs to a metal rapid solidification strip production device and a method thereof, and is especially suitable for the production and use of an amorphous alloy strip. Background technique [0002] At present, the traditional production of metal rapid solidification thin strips, especially the production of amorphous alloy strips, mainly adopts the method of strip throwing in an atmospheric environment. The adjusted master alloy is melted in the melting furnace, and then the molten alloy is sprayed out from the narrow slit of the nozzle and solidified rapidly on the surface of the cooling copper roller rotating at high speed to form an amorphous strip. This way is easy to oxidize some metal elements during the production process. Affect the performance of the metal belt. There are also full-vacuum strips with a width of less than 50mm. The strip mechanism and the final f...
