通过热力学计算,对转炉脱钛过程进行了研究。通过计算得出:转炉冶炼过程前期是去除钢中钛的有利阶段。在转炉冶炼后期,由于钢液温度升高,钢液脱钛所需的氧活度明显增加。通过采用转炉双渣法冶炼、适当提高转炉冶炼终点碳含量,可以达到降低钢中钛含量和避免钢液氧化严重、减轻转炉炉后操作负担的双重目的。 Through the thermodynamic calculation, the decarburization process of the converter was studied. Calculated: the pre-converter smelting process is to remove steel in the favorable phase of titanium. In the late stage of converter smelting, as the temperature of molten steel increases, the oxygen activity required for titration of molten steel increases obviously. Through the use of double-slag converter smelting, the appropriate increase in the carbon content of the end of the converter smelting can be achieved to reduce the titanium content in the steel and to avoid serious oxidation of molten steel to reduce the operational burden of the converter after the dual purpose.
