【摘要】 以冷固球团回转窑直接还原过程中产生的磁性粉为研究对象，采用添加HZ型复台粘结剂进行冷固成型，获得了高强度的团块，可供电炉炼钢，为综合利用冶金资源开辟了一条新的途径。更多还原

【Abstract】 The new technique of the cold-bonding formation of magnetic powders the direct reduction of iron ores was studied in this paper. The research showed that by means of the HZ-type composite binders the high physical strength of green briquettes were obtained. The briquettes could be sent to and electric furnace steelmaking didrectly. Therefore, the new method, the comprechensire utilization of this type ores, could be achieved.更多还原
