The smelting furnace is provided with a first slag discharging port and a second slag discharging port, a bidirectional chute is arranged, the smelting furnace can not stop once slag discharging is started, and a slag ladle is required to be arranged at the first slag discharging port or the second slag discharging port for receiving slag. Before the slag ladle corresponding to the first slag discharging port is fully connected, the slag ladle corresponding to the second slag discharging port needs to wait to the second slag discharging port, so that the smelting furnace is ensured to continuously discharge slag outwards through the chute through the first slag discharging port or the second slag discharging port. The time for filling the empty ladle at one ladle outlet is generally about 15 minutes, which is defined as the period T. The application can avoid the problem of opposite movement congestion on a single track by arranging a unidirectional circulating track for each slag ladle cooling area (200), improves the speed of the track trolley, and ensures that the full slag ladle after the slag ladle is fully connected with the slag ladle is conveyed by the track trolley in the period T, and the empty slag ladle is immediately supplied for position compensation. Meanwhile, at least one slag ladle cooling area and at least one rotary turnout (130) are arranged, the slag ladle cooling areas and the rotary turnouts (130) are in one-to-one correspondence, slag ladles in each slag ladle cooling area can be independently circulated in each slag ladle cooling area, and the slag ladles return to a slag discharge port along a circulating track of a component of each rotary turnout (130).

More specifically, one of the slag ladles corresponding to the first slag discharging port or the second slag discharging port is filled with slag ladles to form full slag ladles, the track trolley moves the full slag ladles to the full slag ladles track (120), and as the first slag discharging port corresponds to the empty slag ladles track (110), the track trolley moves the full slag ladles to the full slag ladles track (120) through the second slag discharging port turnout (142), namely the moving direction of the track trolley on the second slag discharging port turnout (142) is the empty slag ladles track (110) to the full slag ladles track (120). After entering the full package track (120), the track trolley moves to a slag ladle cooling area in a direction away from the front end of the full package track (120), the full slag ladle is replaced by an empty slag ladle in the slag ladle cooling area, and then continues to move to a rotary turnout (130) in a direction away from the front end of the full package track (120), namely, the moving direction of the track trolley on the full package track (120) is away from the front end of the full package track (120). The track trolley then moves to the empty ladle track (110) with the empty ladle through the rotary turnout (130), namely the moving direction of the track trolley on the rotary turnout (130) is from the full ladle track (120) to the empty ladle track (110). After entering the empty package track (110), the track trolley moves to the first slag hole turnout (141) towards the direction close to the front end of the empty package track (110), namely, the moving direction of the track trolley on the empty package track (110) is close to the front end of the empty package track (110).
