钒铁 钒和铁组成的铁合金,主要在炼钢中用作合金添加剂,高钒钒铁还用作有色合金的添加剂。常用的钒铁有含钒40%、60%和80%三种。中国钒铁生产的主要原料是钒钛磁铁矿,经选矿富集后,通过高炉炼出含钒生铁,在雾化炉或转炉吹炼过程中提取钒渣。钒渣经粉碎后配加钠盐(纯碱、食盐或无水芒硝)进行氧化钠化焙烧,使钒成为可溶的偏钒酸钠 (NaVO3),浸取净化后加硫酸铵沉淀出多钒酸铵 [(NH4)2V6O16],再经脱氨熔化,铸成片状五氧化二钒。要求成分为V2O597~99%,P<0.05%,S<0.05%,Na2O+K2O<1.5%。此外也从含钒铁精矿或含钒炭质页岩直接通过化学处理提取五氧化二钒。冶炼钒铁的主要方法为: 电硅热法 片状五氧化二钒用75%硅铁和少量铝作还原剂,在碱性电弧炉中,经还原、精炼两个阶段炼得合格产品。还原期将一炉的全部还原剂与占总量60~70%的片状五氧化二钒装入电炉,在高氧化钙炉渣下,进行硅热还原。当渣中V2O5小于0.35%时,放出炉渣(称为贫渣,可弃去或作建筑材料用),转入精炼期。此时,再加入片状五氧化二钒和石灰,以脱除合金液中过剩的硅、铝等,俟合金成分达到要求,即可出渣出铁合金。精炼后期放出的炉渣称为富渣(含V2O5达8~12%),在下一炉开始加料时,返回利用。合金液一般铸成圆柱形锭,经冷却、脱模、破碎和清渣后即为成品。此法一般用于含钒40~60%的钒铁冶炼。钒的回收率可达98%。炼制每吨钒铁耗电1600千瓦·时左右。 铝热法 用铝作还原剂,在碱性炉衬的炉筒中,采用下部点火法冶炼。先把小部分混合炉料装入反应器中,即行点火。反应开始后再陆续投加其余炉料。通常用于冶炼高钒铁(含钒60~80%),回收率较电硅热法略低,约90~95%。
