Abstract For the investigation of a series of problems in connection with the behaviour of fluorine inblast-furnace smelting,an experimental blast-furnace of an effective volume of about 1 m~3 wasbuilt at our Institute by November 1955 together with the necessary auxiliary equipment.Pao-Tou iron ore,which contains fluorite as one of its chief gangues,was smelted in our experimentalblast-furnace with and without previous sintering,and the planned experiments were completed intwo campaigns which lasted for 22 and 36 days respectively.The smelting characteristics ofour experimental blast-furnace are herewith reported together with data on material balance of allthe constituents including fluorine.It was found that nearly all the fluorine went into the slag,while the fluorine content of tht blast-furnace gas was exceedingly low despite the rather highpercentage of fluorite in the charge.
