介绍了一种高效使用钛渣电炉煤气的方法,为今后钛渣工艺的整体布局提供数据支撑.采用热力学计算方式,得到钛渣电炉产生煤气量与球团金属化率的关系,同时根据实际生产钛精矿预还原球团所需热量的需求,得到钛渣电炉生成煤气热量与实际生产钛精矿预还原球团所需热量之间的关系.结果表明,不同金属化率钛精矿预还原球团用来冶炼钛渣,球团的金属化率无论在什么水平,其生成电炉煤气热量都低于实际球团生产所需热量.若将回收电炉煤气用来生产钛精矿预还原球团需额外增加热源,并且随着球团金属化率升高,补加热量增多.
The paper introduced an efficient way to use electric furnace gas,provides data support for titanium slag process in future.Using thermodynamic calculation,relationship between pellet metallization rate and gas heat generated are obtained.According to the actual heat required in producing in metallized pellet,relationship between gas heat generated smelting in metallized pellet and required for pellet are accepted.The results show that no matter which level in pellet metallization rate,gas heat of generated smelting slag is lower than the actual required of metallized pellet.Thus,additional heat used to produced metallized pellet are required.Also with the increasing pellet metallization rate,the more heat the pellets produced.
