摘要:
The invention relates to metallurgy, in particular to production of metal shot from a molten metal or alloy by casting. According to the claimed method for producing shot, melt fragments, as obtained by passing a melt through a die which passages consist of two successive sections, are cooled by a spilling flow of an air-droplet mixture and are placed into a cooling liquid. Another aspect of this invention is the device for producing shot from a molten metal or alloy for carrying out the claimed method. Yet another aspect of this invention is a device for cooling melt fragments of a molten metal or alloy, as produced by passing a melt through a die, which comprises one or more nozzles for supplying a sprayed cooling air-droplet mixture as a spilling flow to a space under the crucible. Still another aspect of this invention is a die for producing shot from a molten metal or alloy, which is arranged in the crucible bottom and which passages consist of two sections performing the functions of a dosing passage and an isothermal chamber. The technical effect of the claimed invention is production of shot with a high degree of sphericity and fractional composition.
摘要(中):
本发明涉及冶金学,特别涉及通过铸造从熔融金属或合金制造金属丸。 根据所要求的用于制造熔融碎片的方法,通过将熔体通过模具获得,熔融物通过由两个连续部分组成的管道,通过空气 - 液滴混合物的溢出流被冷却并放置在冷却液体中。 本发明的另一方面是用于实施所要求保护的方法的用于从熔融金属或合金制造射丸的装置。 本发明的另一方面是一种用于冷却熔融金属或合金的熔融碎片的装置,其通过使熔体通过模头而产生,该模具包括一个或多个喷嘴,用于将溅射的冷却空气 - 液滴混合物作为溢出流 在坩埚下的一个空间。 本发明的另一方面是一种用于从熔融金属或合金制造射丸的模具,其设置在坩埚底部,并且通道由执行给料通道和等温室的功能的两部分组成。 所要求保护的发明的技术效果是产生具有高度球形度和分数组成的射击。
