The invention relates to metallurgy, in particular to a production of metal shots from a molten metal or an alloy by a 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 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. |
