Preparation method of graphite crucible
The invention relates to the technical field of graphite crucibles, and provides a graphite crucible preparation method, which comprises: a crushing and screening step: crushing and screening a graphitized coke raw material to obtain a particle material; a powder preparation step: grinding the graphitized coke raw material into powder to obtain first powder, wherein the first powder is powdery; a shaping step: shaping the first powder to remove edges and corners of the first powder to obtain second powder; a batching step: batching the granular material and the second powder material according to a preset proportion to obtain a graphitized coke ingredient; a mixing and kneading step: mixing the graphitized coke ingredient with asphalt to obtain a crucible paste material; and a forming step: preparing the crucible paste into the crucible. According to the embodiment of the invention, spheroidizing shaping can be carried out on the ground powder through the shaping step, so that the flowability of the powder can be improved, the compression density of the crucible is further improved, the mechanical property of the crucible is improved, the risk of damage to the crucible is reduced, and the cycle use frequency of the crucible is increased.
本发明涉及石墨坩埚技术领域，提供了一种石墨坩埚的制备方法，包括：破碎筛分步骤：对石墨化焦原料进行破碎、筛分得到颗粒料；制粉步骤：对石墨化焦原料进行磨粉得到第一粉料，所述第一粉料为粉末状；整形步骤：对所述第一粉料进行整形，以去除所述第一粉料的棱角，得到第二粉料；配料步骤：将所述颗粒料和所述第二粉料按照预设配比进行配料，得到石墨化焦配料；混捏步骤：将所述石墨化焦配料和沥青混合得到坩埚糊料；成型步骤：将所述坩埚糊料制备形成坩埚。本实施例通过整形步骤可以对磨粉后的粉料进行球化整形，可以提高粉料流动性，进而提升坩埚压型的密度，改善坩埚力学性能，从而降低坩埚破损的风险，提升坩埚的循环使用次数。
