Preparation method of graphite electrode
The invention discloses a preparation method of a graphite electrode, the graphite electrode comprises solid carbon and a binder, the solid carbon comprises graphite coke, needle coke, pitch coke, metallurgical coke, anthracite, natural graphite and graphite scraps; the binder comprises binding asphalt and synthetic resin, and some auxiliary materials including quartz sand, metallurgical coke particles, calcium oxide, ferric oxide and copper powder are also used in the production and processing process; meanwhile, an impregnant also needs to be prepared, and the impregnant comprises anthracene oil. According to the preparation method of the graphite electrode, calcium oxide, ferric oxide and copper powder are added, so that the strength of the finished graphite electrode can be effectively improved, and the graphite electrode has higher strength; after the graphite material is subjected to dipping treatment, the porosity of the surface of a material product is reduced, the density is improved, the compressive strength is increased, the resistivity of a finished product is reduced, ash powder does not fly during subsequent machining of raw materials, and a smooth product surface can be obtained.
本发明公开了一种石墨电极的制备方法,包括固体炭质和粘结剂,其中固体炭质包括石墨焦、针状焦、沥青焦、冶金焦、无烟煤、天然石墨和石墨碎;且粘结剂包括粘结沥青和合成树脂,并且在生产加工的过程中还使用到一些辅助物料,包括石英砂、冶金焦粒、氧化钙、三氧化二铁和铜粉;同时还需要准备浸渍剂,浸渍剂包括蒽油。该石墨电极的制备方法通过加入氧化钙、三氧化二铁和铜粉,从而能够有效提高成品石墨电极的强度,使其具有更高的强度;通过对石墨材料浸渍处理后,从而减少了材料产品表面的孔度,提高密度,增加抗压强度,降低成品电阻率,还能够使得在后续对原料进行机械加工时灰粉不致飞扬,并且能够得到较光滑的产品表面。
