So, using magnesia and calcia crucible in VIF respectively, the experiments on deep deoxidation by carbon and the phenomenon of oxygen contamination from crucible materials in the molten steel under some temperature and vacuity and oxygen content of the molten steel were made and it were found that properly low melting temperature and vacuity helped to lighten and even avoid oxygen contamination from crucible material and the refining effect of final oxygen content of 5×10-4% in the molten steel was achieved using calcia crucible with better resistance to thermal shock under higher vacuity.

为此，分别采用MgO炉衬与CaO炉衬，在真空感应炉中对钢液用碳进行深脱氧和炉衬供氧现象实验研究，发现：(1)在适当低的熔炼温度和真空度下，可以减轻甚至避免炉衬热分解向钢液供氧；(2)采用热稳定性优越的CaO炉衬，在较高的真空度下可达到钢液最终全氧含量低于5×10-4%的精炼效果。

By the OM and SEM observation of solidification microstructure, the interfacial reaction between TiAl alloy and Al2O3 crucible was serious, and a large number of α-Al2O3 inclusion formed in the solidification microstructure. The interfacial reaction between TiAl alloy and ZrO2 crucible occurred only on the sample surface, but the crucible was not stable at high temperature and a tack coating was formed, clinging tightly with TiAl alloy. C element in the graphite crucible changed the original solidification path of TiAl alloy, and club-shaped γ-TiAl phases formed.

通过用光学显微镜和扫描电镜对凝固组织观察发现，TiAl合金与氧化铝坩埚之间的界面反应较为严重，在凝固组织中形成了大量氧化铝夹杂；TiAl合金与氧化锆坩埚的界面反应仅发生在试样表面，但该坩埚在高温下不稳定，并在试棒表面形成一层无法剥离的粘结层；石墨坩埚中的C元素改变了原有TiAl合金的凝固路径，生成了棒状的γ-TiAl相。
