摘要
在1800kVA敞口电炉上采用自焙电极和粉矿入炉方式,用冶金焦还原钛精矿获得TiO2为76.76%的酸溶钛渣。一半未配还原剂的钛矿在冶炼过程中逐渐加入,炉况顺行,无翻渣踏料现象。钛渣电耗为2200kWh/t,较以往钛渣试验降低500kWh/t渣,钛渣制造成本为1686元/t,较以往钛渣试验的制造成本下降500～700元/t,可被钛白生产商接受。
A kind of acidic titania slag which TiO_2 equals to 76.76% is obtained in the open furnace (1800kVA) which uses baked electrode.Its feature is entering half of titania ore slowly which is not mixed with reducer during smelting.The electricity use 2200kWh/t.slag,the total cost of titania slag equals to 203 US/t.slag which declines 26%.
