Preparation method of high-strength prebaked anode
The invention provides a preparation method of a high-strength prebaked anode. The preparation method mainly comprises the following steps: adding a certain proportion of high-softening-point asphalt to adjust the performance of a binder and improve the permeability and coking rate of the asphalt, and preparing a high-strength and high-density prebaked anode product through the procedures of kneading, profiling, roasting and the like. The prebaked anode has the advantages that the asphalt with a higher softening point has a higher coking value, so a bonded coke hole wall is firm, a fibrous structure is forme, and the prebaked anode has better graphitization easiness; and thus, the mechanical strength, the conductivity and the oxidation resistance of the prebaked anode are improved, and the comprehensive performance of the prebaked anode is improved to a new height.
本发明提供一种高强度预焙阳极的制备方法，主要工艺过程是添加一定比例的高软化点沥青来调节粘结剂的性能，提高沥青的渗透性和结焦率，经过混捏、压型、焙烧等工序得到高强度、高密度的预焙阳极制品。本发明的优势：较高软化点的沥青具有较高的结焦值，粘结焦孔壁结实，结构呈纤维状，具有较好的易石墨化性能，改善了预焙阳极的机械强度、导电性能和抗氧化性能，使预焙阳极的综合性能上升到一个新的高度。
