摘要
预焙阳极约含50～65%石油焦、14～17%煤焦油沥青和15～30%残极返回料。众所周知,残极的数量和清洁度影响阳极的物理性能,如机械强度和空气渗透率,以及羟基反应性。最近的研究工作表明,残极的硬度对预焙阳极物理性能和空气反应性有很大影响。
Prebaked anodes contain about 50 to 65% petroleum coke, 14 to 17% coal tar pitch and 15 to 30% recycled anode butts. It is well known that the amount and cleanliness of the butts influence anode physical properties such as the mechanical strength and permeabiliy as well as the carboxy react- ivitybehaviour. Recent research work has shrwn a tremendous influence of butt's hardness on the physical propeties and air reactivity behaviour of prebakedanodes.
