FEEDING DEVICE FOR ELECTRICAL SHAFT FURNACES WITH AN ELECTRODE-RECEIVING CENTRAL TUBE

摘要

Disclosed is a feeding device for closed shaft furnaces that are attached to a gas extracting device, more particularly low shaft furnaces for melting steel scraps, with a conveyor device leading to the head of the upper tank of the furnace, which is at least integrated in part to the atmosphere in the furnace and a distribution device for distributing the charge. A carrousel (31) receiving the charge carried by a conveyor device (21) is mounted in the head of the furnace (13). Said carrousel is guided in the head of the furnace (13) on a guide path (65) fixed on the jacket (18) of the upper tank of the furnace (12) above the gas extracting device (17) in such a way that it can rotate and comprises shutter elements (41) attached to the actuators (41).
