The invention discloses a preparation method for graphite cylinders and relates to preparation methods for the graphite cylinders. The preparation method is used for solving the problems in the existing graphite cylinder preparation processes that materials are wasted, the preparation period is long, the preparation cost is high, the energy consumption of preparation is high, and the stability of prepared graphite cylinders is poor. The preparation method comprises the steps: (1) weighing raw materials: weighing the raw materials: 74% to 78% (by mass) of dry matter and the balance of asphalt; (2) carrying out blank forming: carrying out vibration forming in a mold; (3) roasting graphite cylinder blanks in a roasting furnace; and (4) carrying out graphitization on the graphite cylinder blanks. According to the preparation method, the prepared graphite cylinders are reasonable in material structure design and dependable in quality, roasting time, the raw materials, burned coal, labor hours and binding resin can be saved compared with those of the traditional production processes, and thus the preparation method has the effects of energy saving and environment-friendliness; and by adopting a vibration forming technology, the graphite cylinders are compact in structure, high in thermal stability and good in chemical stability. The preparation method is applicable to the preparation of the graphite cylinders.
