Abstract
PURPOSE: To decrease damage of tap hole and to improve dust conditions, by covering a tap hole and a cinder notch of a blast furnace air-tightly, and by opening or closing the molten material flow under press. control.
CONSTITUTION: A tap hole 8 of a blast furnace is covered with a main press. vessel 11, to which is connected a removable, separated press. vessel 12. A tap-opener 21 for opening the tap hole 8 is shown in the maib press. vessel 11. The opener 21 and a closer can be removed with a valve 19 closed and a valve 20 opened. In tapping molten iron, the vessels 11, 12 are integrated to one airtight system with a valve 16 closed and a valve 14 opened. Then the vessel 11 is pressurized by means of a press. controller 15 to a press. equal to that of the furnace. Successively, after the tap hole 8 is opened by an opener 21, the press. of the vessel 11 is removed so as to tap molten iron 3 tradually. When appropriate quantity of the molten iron is reserved in the vessel 12, it is poured into a ladle 10 with the valve 16 opened. In closing the tap hole, the vessel 11 is pressurized with the valve 16 closed, and the tap hole 8 is closed by means of an airtight operation case 18 and a closer. A cinder notch is operated in a similar way as with a tap hole.
