CHARGING DEVICE FOR LOW BLAST FURNACES

摘要

The invention relates to a charging device for low blast furnaces, especially for arc furnaces used for producing scrap iron, which can be closed by a cover connected to a gas discharging unit and over which a charging device can be placed after removal of the cover from the furnace shaft. Said charging device (31) has an upper part (32) and a lower part (34). Said upper part (32) is designed as a charging container (32) having a gas permeable bottom (33) which can be opened. The lower part (33) is designed so that its opening (35) corresponds to the upper edge (19) of the upper vessel (13) of the furnace. A support (51) is provided outside the low blast furnace (11). The charging device (31) can be deposited on said support having a level which is substantially below the upper edge (19) of the upper vessel (13) of the furnace. Said support (51) has a connection means for being connected to the gas discharging unit (29). A lifting device (41) is also provided for depositing the charging device (41) on the support (51) and for lifting it slightly above the upper edge (19) of the upper vessel (13) of the furnace. A displacement device (42) is also provided for approaching or pulling away the charging device (31) from the low blast furnace (11).
