Abstract

PURPOSE:To permit quick and safe repairing of a blast furnace without the complete stoppage of its operation even at the time of occurrence of accident by opening or closing the lower end of the opening of a slant flow chute. CONSTITUTION:The slewing arm 7 by which the seal flap 4 is always moved out of a path for charging raw materials during the operation is provided in proximity to a charging port and the expanded portion 10 by which the slewing arm 7 is allowed to move upwardly beyond the furnace head surface 1 is formed. The slewing shaft 8 is turned by the reciprocal action of the oil-pressure cylinder 12 through the slewing lever 11 and the seal flap 4 is moved between the closed position, as shown by the solid line, and the opened position, as shown by the broken line, by the slewing arm 7. The seal flap 4 is upwardly pushed with the roller 14 as a fulcrum and the diffusion of gas into the air is completely shutout in order to ensure the exact air- tight contact of the seal flap 4 with the seal lip 6.
