Abstract
Systems and methods are presented for producing shot from molten material, in which two or more sprays of inert gas, such as an upper or primary spray followed by one or more lower or secondary sprays, are used to break apart large molten droplets into shot as the molten material is dropped from a crucible orifice. The upper or primary gas feed in one application acts to initially break the stream or droplets into initial droplets of a lesser size or to flatten the droplets, with the second spray then breaking up the intermediate droplets into yet smaller shot particles to be cooled and collected.
Claims23
A system for producing shot from molten material, comprising:
- a container storing molten material, the container comprising an orifice located along a vertical axis, the orifice allowing initial droplets of the molten material to fall along the axis;
- and
- a multilevel gas feed apparatus below the container, the gas feed apparatus comprising:
- a first gas feed mechanism located below the container and having at least one gas outlet laterally spaced from the axis for directing gas flow toward the axis to impact the initial droplets at a first region to form secondary droplets of the molten material, and
- a second gas feed mechanism located below the first gas feed mechanism and having at least one gas outlet laterally spaced from the axis for directing gas flow toward the axis to impact the secondary droplets at a second region below the first region to form shot particles of the molten material.

- and
- the gas outlets of the first gas feed mechanism being oriented such that none of the gas outlets of the first gas feed mechanism are directly above any of the gas outlets of the second gas feed mechanism.
