A ladle conveying system for conveying ladles, each of which receives a melted product from tap outlets (2a,2b,2c) of a calcium carbide producing furnace, between a product receiving region including the tap outlets (2a,2b,2c) and a product unloading region away from the furnace, comprising: a loop track for connecting the product receiving region and the product unloading region; a first ladle group comprising a plurality of ladles and a plurality of bogies, wherein each of the ladles is placed on each of the bogies, the bogies can run on the track, and adjacent bogies are linked to each other; a second ladle group, which is disposed opposite to the first ladle group on the track, comprising a plurality of ladles and a plurality of bogies, wherein each of the ladles is placed on each of the bogies, the bogies can run on the track, and adjacent bogies are linked to each other; a first wire linked to the leading bogie, in the clockwise direction on the loop track, of the first ladle group; a second wire linked to the leading bogie, in the counterclockwise direction, of the second ladle group; a linkage wire to tightly link the rearmost bogie, in the clockwise direction, of the first ladle group with the rearmost bogie, in the counterclockwise direction, of the second ladle group; a first winch to reel the first wire to move the first ladle group in the clockwise direction along the track from the product receiving region to the product unloading region; and a second winch to reel the second wire to move the second ladle group in the counterclockwise direction along the track from the product receiving region to the product unloading region, wherein, when the first ladle group is towed by the first wire to move on the track from the product receiving region to the product unloading region in the clockwise direction, the linkage wire tows the second ladle group to move from the product unloading region to the product receiving region in the clockwise direction, while when the second ladle group is towed by the second wire to move on the track from the product receiving region to the product unloading region in the counterclockwise direction, the linkage wire tows the first ladle group to move from the product unloading region to the product receiving region in the counterclockwise direction. a loop track for connecting the product receiving region and the product unloading region; a first ladle group comprising a plurality of ladles and a plurality of bogies, wherein each of the ladles is placed on each of the bogies, the bogies can run on the track, and adjacent bogies are linked to each other; a second ladle group, which is disposed opposite to the first ladle group on the track, comprising a plurality of ladles and a plurality of bogies, wherein each of the ladles is placed on each of the bogies, the bogies can run on the track, and adjacent bogies are linked to each other; a first wire linked to the leading bogie, in the clockwise direction on the loop track, of the first ladle group; a second wire linked to the leading bogie, in the counterclockwise direction, of the second ladle group; a linkage wire to tightly link the rearmost bogie, in the clockwise direction, of the first ladle group with the rearmost bogie, in the counterclockwise direction, of the second ladle group; a first winch to reel the first wire to move the first ladle group in the clockwise direction along the track from the product receiving region to the product unloading region; and a second winch to reel the second wire to move the second ladle group in the counterclockwise direction along the track from the product receiving region to the product unloading region, wherein, when the first ladle group is towed by the first wire to move on the track from the product receiving region to the product unloading region in the clockwise direction, the linkage wire tows the second ladle group to move from the product unloading region to the product receiving region in the clockwise direction, while when the second ladle group is towed by the second wire to move on the track from the product receiving region to the product unloading region in the counterclockwise direction, the linkage wire tows the first ladle group to move from the product unloading region to the product receiving region in the counterclockwise direction.
