Abstract: A method and device for producing shots are provided where the yield is improved. In a space (5) for forming molten drops, which space is surrounded by water (1) in a tank (20), by a cover (3) to cover an area surrounding a disc (2) that is located above the water and rotates, and by a tundish (4) that penetrates through the cover, a gas is discharged though an opening (6) that is formed in the cover and the film (9) of the water is formed on the inner surface of the cover. The molten metal (10) flows through the hole (11) in the bottom of the tundish to be supplied onto the rotating disc. The molten drops are formed by centrifugal force from the molten metal that has been supplied to the disc. Then the molten drops are caused to collide with the film of the water on the inner surface of the cover, to be divided into the droplets that are smaller than the molten drops. The droplets are cooled and solidified.

Abstract: A melting work device and a melting work method by which work can be easily performed on a melting furnace without a worker approaching the melting furnace. A melting work device performs work on a melt obtained by melting a material in a melting furnace. The melting work device has a drive mechanism; and a plurality of work tools that are operated by the drive mechanism; wherein the drive mechanism is able to move the work tools in an arbitrary direction at an arbitrary location above the melting furnace.
