| 摘要 |
An apparatus for vitrifying blast furnace slag, which comprises: an endless conveyor belt formed by endlessly connecting a plurality of rectangular cooling metal members, each of said cooling metal members having a plurality of narrow and deep cooling grooves on the outer surface thereof for rapidly cooling and solidifying a molten blast furnace slag into a vitreous blast furnace slag; a driving means for travelling said endless conveyor belt; a molten slag container, arranged above the upstream of the upper forwarding position of said endless conveyor belt, for pouring a molten blast furnace slag into said cooling grooves; a stripper arranged, in the upstream of the lower returning position of said endless conveyor belt, at a prescribed position adjacent to the back surface of said endless conveyor belt, for taking out a cooled and solidified vitreous blast furnace slag in said cooling grooves; and, a cooling means arranged at a prescribed position in the lower returning position of said endless conveyor belt, for sequentially cooling said cooling metal members heated by the high-temperature molten blast furnace slag poured into said cooling grooves.
