ABSTRACT:
A top closing device for shaft furnaces, particularly blast furnaces, including an inlet hopper with inlet pipe, a rotating, vertically non-adjustable chute carrier with rotary drive, a pivotable chute in the furnace interior with external drive means, and sealing members between the rotating and stationary components. The rotating chute carrier is mounted with a gear ring attached to a flange in a ball bearing slewing rim arranged on a catch basket. The rotary movement of the rotating chute carrier is effected outside of the furnace space by an electric motor drive with pinion. The catch basket is arranged on the furnace support ring of the gas seal hood. The pivoting or tilting movement of the chute relative to the furnace axis within the rotating chute carrier is effected by a hydraulic or electromechanical drive outside of the furnace space. An annular sealing member for sealing relative to the rotating chute carrier is mounted on the furnace support ring next to the flange of the catch basket. An annular sealing member for sealing relative to the stationary inlet pipe is mounted on the inner flange of the chute carrier.
