摘要
以钛白粉为原料,采用铝热还原法制备Ti-Al中间合金的冶炼工艺。采用单因素试验,得到最佳工艺参数:配铝系数为1.7,单位热效应为2850 kJ/kg,配石灰系数为0.9。该工艺条件下,冶炼效果较好,合金收率较高。对所得Ti-Al中间合金进行了XRD衍射,结果表明:Ti-Al中间合金的主要物相组成为Ti3.3Al。
Taking titanium pigment as raw material, experiments were conducted to prepare Ti-AI master alloy by aluminothermic reduction. Through single factor experiments, the optimum result was obtained with aluminum adding coefficient of 1.7, unit thermal effect of 2850 kJ/kg and lime adding coefficient of 0.9. Under this process condition, good smelting results and high yield of alloy were achieved. Analyzed by XRD diffraction, the phase compositions of the Ti-A1 master alloy mainly consisted of Tia.3A1.
