为了研究包头铁矿的冶炼特性及由于矿石含氟所引起的一系列问题起见,我所于1955年11月筹建了有效容积约为1米~3的实验高炉一座及全部附属设备。1955年11月30日至12月8日及12月20日至12月24日进行了二次试炉。经过设备上的改进后,于1956年1月20日至2月11日及4月23日至5月29日进行了二次冶炼试验,获得设计上所要求的的主要数据后停炉。在实验高炉冶炼试验期间并进行了4次物质平衡的试验。结果发现绝大部分的氟进入炉渣中,进入炉尘中的氟石多,而高炉煤气中的氟极低.
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.
