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。
An efficient method of using titanium slag electric furnace gas is introduced to provide data support for the overall layout of the titanium slag process in the future. The relationship between the amount of gas generated by the titanium slag electric furnace and the metallization rate of the pellets is obtained by the thermodynamic calculation method. At the same time, according to the demand of the heat required for the prereduction pellets of the titanium concentrate, the heat of the gas generated by the titanium slag electric furnace and the actual production of titanium dioxide The relationship between the calories required for the ore prereduction pellets. The results show that different metallization rates of titanium concentrate prereduced pellets are used to smelt titanium slag. No matter what the metallization rate of the pellets, the calorific value of electric furnace gas generation is lower than that of the actual pellet production. If the recovery of electric furnace gas used to produce titanium concentrate prereduction pellets need additional heat source, and with the pellet metallization rate, additional heat increased.
