High-purity graphite isostatic pressing forming process
The invention discloses a high-purity graphite isostatic pressing forming technology. The technology comprises the following steps that S1, raw materials are subjected to crushing treatment and burdening; s2, stirring, mixing and kneading the carbonaceous particle material, the powder material and a binder; s3, carrying out plastic deformation on the mixed and kneaded carbonaceous paste in forming equipment; s4, roasting; s5, graphitizing the carbon material. Before the step S1, carrying out intermediate crushing, grinding, screening and batching treatment on large calcined petroleum coke and needle coke; the isostatic pressing graphite produced through the high-purity graphite isostatic pressing forming technology has the advantages of being compact in organization structure, high in hardness, resistant to oxidation, not prone to cracking under the rapid cooling and rapid heating working condition, stable in overall performance and capable of meeting the use requirement.
本发明公开一种高纯石墨等静压成型工艺，包括如下步骤：S1：原料的破碎处理和配料；S2：将碳质颗粒料和粉料与粘结剂搅拌混捏；S3：将混捏后的碳质糊料在成型设备内塑性变形；S4：焙烧；S5：碳材料石墨化，所述步骤S1之前还包括对大块煅后石油焦和针状焦进行中碎、磨粉、筛分、配料处理；该高纯石墨等静压成型工艺生产出的等静压石墨具有组织结构致密、硬度高和抗氧化性能，且在急冷急热工况条件下也不易开裂，整体性能稳定，满足使用需求。
