ABSTRACT:
Fe-B molten metal for producing amorphous alloys are produced in a low cost by using a vertical furnace wherein beds packed with a carbonaceous solid reducing agent are formed and two or three stages of tuyeres are provided in the lower portion of said furnace, feeding a preliminarily reduced powdery iron ore into the furnace through the upper stage of tuyeres together with hot air and feeding boron oxide or boric acid into the furnace through the lower stage of tuyeres together with hot air and, if necessary blowing hot air into the furnace through the lowest stage of tuyeres. In stead of the above described vertical furnace, a usual blast furnace provided with one or two stages of tuyeres at the lower portion of said furnace is used. In this case, sintered iron ore, pellet-formed iron ore or lump iron ore is fed from the top of the furnace and powdery boron oxide or boric acid is fed through the tuyeres.
