【摘要】：研究了在两阶段氢气还原法生产钼粉的过程中还原温度、料层厚度等已达到设备极限的情况下,通过提高一段还原氢气露点以继续提高钼粉粒度的可行性。结果表明,露点从-20℃提高到20℃后,钼粉颗粒的微观形貌仍基本呈近球形,且团聚程度更低,小颗粒更少;激光粒度分布与费氏粒度结果均显示钼粉的粒度有明显提高。
[Abstract]:The feasibility of increasing the grain size of molybdenum powder by increasing the dew-point of one-stage reduction hydrogen was studied under the condition that the reduction temperature and the thickness of the layer reached the limit of the equipment in the process of producing molybdenum powder by two-stage hydrogen reduction method. The results show that when the dew point is increased from -20 鈩，
