摘要
阐述了如何在电炉炉底排铅的方法,即让铅液通过砖体气孔及砖缝的渗透而汇集于集铅槽,然后从排铅口定期排放。对于排铅槽标高位置的确定,提出了一种比经验公式更为精确的方法:即利用多层平壁稳定态热传导公式和迭代试差法,以此确定出排铅槽位置和排铅温度,避免了因为排铅槽位置不合理带来的铅回收率不高的情况。借用高炉排铅的工程经验,设计出“双丰”字型的排铅槽结构。从理论上来看,这样的排铅槽结构更合理,能更大限度地利用炉底中心区来回收铅。
In this article, the method of how to discharge lead at the bottom of submerged arc furnace is introduced in smelting silicon-manganese. Namely , let the lead liquid pass the pore and aperture of brick to permeate to gather together in discharge lead grooves, then from the lead groove periodically discharge up to put. A kind of more accurate method than empirical formula was putted out for confirming the discharging lead slot elevation position, that is, which made use of the stabilizing hot conduction formula of multilayer even wall and iteration so that the temperature of the groove will be obtained exactly, lead can be reclaimed as more as possible. Based on the engineering experiences at blast furnace, the new form discharging-lead groove was designed, which is more reasonable, and the centre zone of submerged furnace's bottom can be used better for gathering lead.
