一、前言第十四冶炼厂1号电炉自投入生产以来,处理的炉料均系经回转窑干燥后含水份3～5％的粉矿。1964年11月,1号隧道窑建成生产后,才开始处理部分粒矿。尽管电炉处理粒矿的时间很短,但已显示了它的显著优越性。炉料经制粒干燥后,物理化学性质均得到一定改善,在同样负荷下,电炉生产能力较处理粉矿时提高15～18％,单位电耗相应降低18～19％;由于粒矿的透气性较好,能在炉内形成比较稳定的料
I. Foreword The fourteenth smelter No. 1 electric furnace since put into production, the processing of the charge are the rotary kiln drying moisture content of 3 to 5% of the ore. In November 1964, No. 1 tunnel kiln was completed and put into production before it began to deal with some of the pellets. Although the EAF has a very short processing time, it has shown its outstanding advantages. After the pellets were dried, the physical and chemical properties were all improved. Under the same load, the EAF production capacity was increased by 15-18% and the unit power consumption was reduced by 18-19% when the powder ore was processed. Due to the permeability of the pellets Better, in the furnace to form a more stable material
