Carbon-carbon crucible support and preparation method thereof
The invention provides a carbon-carbon crucible support and a preparation method thereof, and relates to the technical field of crucible supports. The preparation method comprises the following steps: carrying out profiling needling by using a carbon fiber net tire and carbon fiber cloth to prepare a crucible support prefabricated body which has the same radian as a carbon-carbon crucible support product and has no edges and corners on the surface; spraying resin on the surface of the crucible support preform, and then carrying out heating and compression molding to obtain a crucible support green body; and sequentially carrying out densification treatment and high-temperature treatment on the crucible holder blank, and then machining to obtain the carbon-carbon crucible holder product. The carbon-carbon crucible support provided by the invention is uniform in product density, stable in performance and low in cutting rate.
本申请提供了一种碳碳埚托及其制备方法，涉及埚托技术领域。制备方法包括：利用碳纤维网胎和碳纤维布进行仿形针刺，制得与所述碳碳埚托产品弧度相同但表面无棱角的埚托预制体；将所述埚托预制体表面喷涂树脂后进行加热模压成型，获得埚托坯体；对所述埚托坯体依次进行增密处理、高温处理后，再进行机加工，即得到所述的碳碳埚托产品。本申请提供的碳碳埚托的产品密度均匀，性能稳定且切削率低。
