摘　　要：在低碳MgO-C材料的结合剂酚醛树脂中加入自制的FeMo合金粉和FeNi合金粉,研究其对低碳MgO-C材料性能的影响。结果表明:添加FeMo合金粉和FeNi合金粉后,低碳MgO-C材料试样的致密度、常温力学性能和抗热震性能均提高,试样中晶态碳和镁铝尖晶石的量增多,碳纳米管的长径比和镁铝尖晶石的晶粒尺寸增大。添加FeNi合金粉的效果好于添加FeMo合金粉的。Self-synthesized FeMo and FeNi alloy powders were added into phenolic resin to investigate their effect on the properties of low carbon MgO-C refractories.The results show that after adding FeMo and FeNi alloy powders,the density,the cold mechanical properties,and the thermal shock resistance of the MgO-C refractories are improved,the amount of crystalline carbon and magnesium aluminate spinel increases,and the length to diameter ratio of carbon nanotubes and the grain size of magnesium aluminate spinel increase;moreover,FeNi alloy shows better effect than FeMo alloy.
