Claims

[Scope of utility model registration request]

A seal cylinder is provided on the top side wall of the furnace between the bell at the top of the blast furnace and the movable armor, and the rear end of the charging chute, whose tip is located away from the center of the furnace, is pivoted within the seal cylinder. The lower part of the fixed charging chute, which is vertically rotatable and communicates with the charge supply hopper outside the furnace, is connected through the seal cylinder to communicate with the rear end of the charging chute inside the furnace. A charging device for a blast furnace, further comprising: a driving device for rotationally driving the charging chute in the vertical direction, provided near the seal cylinder outside the furnace.
