摘　　要：通过对预焙阳极炭块空气渗透率影响因素的实验研究,从配料角度,假设原料、工艺、设备技术参数保持不变,增加生坯粉料配入量、提高粉料纯度,以及根据沥青配比确定焙烧升温曲线等途径降低空气渗透率;实验证明增加粉子用量、提高粉子纯度,以及适宜生坯沥青含量对应的焙烧升温速率,是降低阳极空渗率的关键因素。Through the experimental study on the influencing factors for air permeability of prebaked anode carbon block,from the angle of batching,assuming that the raw material,process and equipment technical parameters remain unchanged,the air permeability is reduced by increasing the amount of green powder,improving the purity of powder and determining the baking temperature curve based on the asphalt ratio.The experiments show that the key factors to reducing the anode air permeability are to increase the amount of powder,increase the purity of powder and the baking temperature rising rate corresponding to the content of green asphalt.
