Abstract

Изобретение относится к металлургии, в частности к производству металлической дроби из расплава металла или сплава методом литья. В заявляемом способе получения дроби фрагменты расплава, полученные пропусканием расплава через фильеру, каналы которой состоят из двух последовательно расположенных участков, охлаждаются ниспадающим потоком воздушно-капельной смеси и размещаются в охлаждающей жидкости. Другим аспектом настоящего изобретения является устройство для получения дроби из расплава металла или сплава для осуществления заявляемого способа. Еще одним аспектом настоящего изобретения является устройство охлаждения фрагментов расплава металла или сплава, полученных пропусканием расплава через фильеру, включающее одну или несколько форсунок для подачи в подтигельное пространство распыленной охлаждающей воздушно-капельной смеси ниспадающим потоком. Еще одним аспектом настоящего изобретения является фильера для получения дроби из расплава металла или сплава, устанавливаемая в днище тигля, каналы которой из двух участков, выполняющих функции дозирующего канала и изотермической камеры. Техническим результатом заявляемого изобретения является получение дроби с высокой степенью сферичности и фракционного состава.The invention relates to metallurgy, in particular to the production of metal shot from a molten metal or alloy by casting. In the inventive method for producing shot, fragments of the melt obtained by passing the melt through a die, the channels of which consist of two successively located sections, are cooled by a falling flow of an air-droplet mixture and placed in a cooling liquid. Another aspect of the present invention is a device for producing shot from a molten metal or alloy for implementing the inventive method. Another aspect of the present invention is a device for cooling fragments of a melt of metal or alloy obtained by passing the melt through a die, including one or more nozzles for supplying a sprayed cooling air-droplet mixture in a falling flow into the sub-crucible space. Another aspect of the present invention is a die for producing shot from a molten metal or alloy, installed in the bottom of the crucible, the channels of which are from two sections that act as a metering channel and an isothermal chamber. The technical result of the claimed invention is to obtain a shot with a high degree of sphericity and fractional composition.
