The invention discloses a preparation method of a crucible tray of a single crystal furnace. The preparation method comprises the following steps: cutting carbon fibers into short fibers by a cuttingmachine, dispersing the short fibers, uniformly mixing the cut and dispersed short fibers with phenolic resin powder, and performing hot pressing on the mixture by using a mold; demolding a product formed by pressing, and then carrying out a machining treatment; carrying out a surface density enhancement treatment on the machined crucible support; and carrying out a high-temperature purification treatment on the densified crucible support. The preparation method has the advantages that firstly, the prepared crucible support has the advantages of low cost, short preparation period and good mechanical property; secondly, compared with a carbon fiber woven prefabricated body post-carburization process, the cost of the scheme is lower, the mechanical property difference is small, and the preparation period is one third of the carbon fiber woven prefabricated body post-carburization process.
本发明公开了一种单晶炉坩埚托盘的制备方法，包括以下步骤：将碳纤维丝用裁剪机器裁剪成短纤维并进行分散处理；将裁剪好分散后的短纤维和酚醛树脂粉均匀混合，利用模具对其进行热压；将压制成型的产品脱模后进行机械加工处理；将机加完成后的埚托进行进行表面致密度增强处理；将增密完成的埚托进行高温提纯处理。本发明所述的一种单晶炉坩埚托盘的制备方法，首先，此方法制备出来的埚托具有成本低，制备周期短，力学性能好的优点，其次，与碳纤维编制预制体后渗碳工艺相比较，此方案的成本更低，且力学性能差距不大，制备周期为碳纤维编制预制体后渗碳工艺的三分之一。
