Abstract

Discharging device of a shaft furnace with the purpose of continuous and even discharge of charged material at high temperature, which material has been reduced in a high temperature atmosphere by means of reducing gas comprising as main components CO and H2 from lumpy iron ore, prepared in advance by pelletizing or granulation having cooling means in which a stationary table is provided at the lower end of the wall of the shaft furnace having a circular form in the horizontal cross-section with an annular clearance being formed between the wall and the stationary table through which the charged materials may pass. A rotary shaft extends through the stationary table which fixedly supports a rotor provided above the stationary table which rotor shape and diameter have a specific relation with the inside diameter of the furnace. Each of the stationary table, the rotor and the shielding wall of the furnace has hollow space formed therein so that it forms a jacket through which cooling fluid can be circulated. An inlet and an outlet pipe are arranged within the rotary shaft for supplying the cooling fluid to the jacket formed in the rotor.
