摘　　要：钼属于难变形材料,室温塑性差,制作大型薄壁坩埚困难较大。利用普通旋压加强力旋压的复合加工方式,在加热条件下成功制得了所需的钼坩埚。所得产品尺寸、表面质量满足要求。As molybdenum is the difficult deformation material, and its plasticity at room temperature is poor, the manufacturing large thin wall crucible is difficult. Under heating conditions, the molybdenum crucibles were produced by using combined processing method （conventional spinning and power spinning）. The dimension and surface quality of the product meet requirements.
