ABSTRACT:
A method and an apparatus for manufacturing a crystalline blast furnace slag, which comprises: endlessly connecting at prescribed intervals a plurality of rectangular metal cooling bodies each with a hollow for cooling water, to form a plurality of cooling grooves with a width at the top end thereof of from 40 to 80 mm corresponding to said prescribed intervals and a depth of from 100 to 300 mm and becoming narrower toward the depth thereof, each between two adjacent ones of said cooling bodies; continuously pouring a molten blast furnace slag sequentially into said plurality of cooling grooves in an atmosphere of an inert gas and/or a reducing gas, while moving said plurality of cooling bodies endlessly connected in circulation in the connecting direction thereof; and, circulating a cooling water through said hollows for cooling water of said plurality of cooling bodies during the pouring of said molten blast furnace slag into said plurality of cooling grooves, to cool said plurality of cooling bodies, thereby cooling and solidifying said molten blast furnace slag poured into said plurality of cooling grooves by the contact with mutually facing outer surfaces of two adjacent ones of said cooling bodies thus cooled, to manufacture a crystalline blast furnace slag.
