Preparation process of carbon-carbon crucible in continuous graphitization furnace
The invention discloses a preparation technology of a carbon-carbon crucible in a continuous graphitization furnace, and belongs to the technical field of carbon fiber composites.The preparation technology comprises the ten steps of prefabricating, pretreatment, CVI hardening, CVI densification, high-temperature heat treatment, rough turning, dipping-carbonization, finish machining, CVD and metal coating, the ash content of the carbon-carbon crucible finished product prepared through the technology ranges from 20 ppm to 50 ppm, the service life of the product is guaranteed, and the production cost is reduced. And the process improves the carbon yield, shortens the construction period, reduces the cost, and can resist the high temperature of 3000 DEG C.
本发明公开了一种连续式石墨化炉中碳碳坩埚的制备工艺，属于碳纤维复合材料技术领域，包括预制件、预处理、CVI硬化、CVI增密、高温热处理、粗车、浸渍‑碳化、精加工、CVD、金属涂层10个步骤，其工艺制备得到的碳碳坩埚成品灰分在20‑50ppm，保障了产品寿命，且该工艺提高了碳收率，缩短工期，降低成本，且可耐3000℃高温。
