Manufacturing method of graphite in graphite boat
The invention discloses a graphite boat graphite manufacturing method, which comprises: material preparation: carrying out heat treatment on carbon raw materials comprising petroleum coke, needle coke and coal pitch at a high temperature of 1250-1350 DEG C, removing water and volatile components contained in the carbon raw materials, improving the physical and chemical properties of the raw materials, grinding, carrying out crushing treatment on the petroleum coke and the needle coke subjected to heat treatment, and carrying out heat treatment on the crushed petroleum coke and the crushed needle coke to obtain the graphite boat graphite. The preparation method comprises the following steps: preparing petroleum coke, screening the petroleum coke, kneading: fully mixing 10-20% by weight of petroleum coke powder and 60-90% by weight of coal pitch with the particle size of D85-D95 [mu] m for 50-100 minutes, and flaking: carrying out plastic deformation on the kneaded carbonaceous paste under the action of external acting force applied by forming equipment to prepare a green body; the mold has the advantages of being high in structural strength, uniform in structural forming, capable of improving the yield and reducing air holes and low in ash content.
本发明公开了一种石墨舟石墨的制造方法,包括以下步骤:备料:碳质原料包括有石油焦、针状焦与煤沥青,在高温下进行热处理,温度为:1250℃‑1350℃,排除所含水分和挥发分,提高原料理化性能,磨粉:热处理后的石油焦和针状焦进行粉碎处理工作,并对石油焦进行筛分处理,混捏:将重量为10%~20%石油焦粉与粒度为D85~D95μm的60%~90%煤沥青进行充分混合,粉料混合时间为50~100分钟,轧片:将混捏好的碳质糊料在成型设备施加外部作用力下产生塑性变形制成生坯;本发明具有结构强度高、结构成型均匀、提高成品率、减少气孔、灰分较低的优点。
