煅后无烟煤掺配比例对预焙阳极性能影响的研究

Study on Effect of Calcined Low Ash Anthracite Coal Blending Ratio on Performance of Prebaked Anode

针对目前铝用优质石油焦的供应紧张及我国无烟煤资源丰富的现状,在全面考虑无烟煤与石油焦特性差异的基础上进行研究。依据振实密度的正交实验,确定出不同煅后无烟煤掺配比例下的最佳配方。控制合理添加量在20%~30%的情况下,煅后无烟煤替代部分石油焦生产铝用预焙阳极是可行的。

After compared with the properties of anthracite and petroleum coke characteristics, carried out the following study. On he basis of the above analysis, the added principle of calcined anthracite was determined. It is feasible to add 20% to 30% calcined anthracite in petroleum coke to produce aluminum prebaked anode.
