Short-flow preparation method for graphite
The invention discloses a short-flow preparation method for graphite, and relates to the technical field of graphite preparation. The invention aims to solve the problems of a relatively long graphite preparation process and high energy consumption. The method comprises the following steps: grinding raw materials: respectively grinding calcined petroleum coke and asphalt sheets into fine powder, and conducting screening; briquetting: preparing fine powder of the calcined petroleum coke and fine powder of the asphalt sheets according to a certain ratio according to a size fraction, conducting full and even mixing and performing briquetting; roasting-dipping: roasting a molded green body obtained after briquetting under the condition of isolating air, performing cooling to a certain temperature after roasting is finished, and directly dipping a roasted product in asphalt liquid; and graphitization: carrying out graphitization treatment on the dipped product. According to the preparation method, the traditional working procedures of kneading, flaking, secondary grinding, waste heat treatment before dipping, roasting after dipping and the like are omitted, so production efficiency is improved and energy consumption is reduced; and the prepared product still has excellent performance by optimizing the particle size composition of raw materials, roasting and a graphite heating curve.
本发明公开了一种短流程制备石墨的方法，涉及石墨制备技术领域，为解决石墨制备过程较长、能耗高的问题；本发明包括原料磨粉：分别将煅后石油焦和沥青片磨成细粉并筛分；压型：按粒级以一定比例配置煅后石油焦细粉、沥青片细粉物料，充分混匀后压型；焙烧‑浸渍：将压型后的成型生坯在隔绝空气下焙烧，焙烧结束后待冷却至一定温度，焙烧品直接在沥青液中浸渍；石墨化：对浸渍品石墨化处理；本发明省去了传统的混捏、轧片、二次磨粉、浸渍前余热和浸渍后焙烧等工序，提高了生产效率，降低了能耗，并通过优化原料粒度组成、焙烧和石墨升温曲线，使得所制产品仍具有优良的性能。
