The invention belongs to the technical field of graphite electrodes, and particularly relates to a high-temperature-resistant graphite electrode forming processing method which comprises the followingsteps: step 1, calcining raw materials: carrying out high-temperature calcining treatment on carbonaceous raw materials under the condition of isolating air to obtain a paste material; step 2, extrusion forming: specifically, enabling the paste material to pass through a cylindrical die nozzle under pressure, so that the paste material becomes a cylindrical blank; step 3, roasting the blank: roasting the blank under the condition of isolating air; step 4, blank dipping: dipping the roasted blank into engine oil for more than 10 hours to enable the engine oil to permeate into the blank; and step 5, machining: specifically, subjecting the impregnated blank to machining through turning, milling, drilling and grinding methods. In the roasting process of the graphite electrode, only a internalthread ring needs to be rotated when a cover plate is opened and closed, and the sealing effect is improved; when the graphite electrode is fed into a tank body, the graphite electrode is prevented from colliding with the side wall of a roasting cavity.
本发明属于石墨电极技术领域，具体涉及一种耐高温石墨电极成型加工方法，包括以下步骤：步骤一、原料煅烧：将碳质原料在隔绝空气的条件下进行高温煅烧处理，得到糊料；步骤二、挤压成型：在压力下使得糊料通过圆柱形的模嘴，糊料成为圆柱形的胚料；步骤三、胚料焙烧：将胚料在隔绝空气的条件下进行焙烧；步骤四、胚料浸渍：将焙烧过的胚料浸入机油内十个小时以上，使得机油渗入胚料内部；步骤五、机械加工：采用车削、铣削、钻削和磨削的方法对浸渍后的胚料进行加工即可。本发明对石墨电极进行焙烧过程中，打开和关闭盖板时只需转动内螺纹环，且提高了密封效果；本发明将石墨电极送入罐体内时，避免了石墨电极与焙烧腔侧壁发生碰撞。
